How to turn on the turbo timer on Starline

To program the turbo timer in the Starline A91 alarm system, you must follow the steps:

1. Operate the key marked with an asterisk icon. The driver holds the button until the buzzer gives a double signal, and then presses the button again (briefly).
2. A combined press of the button turns on the flashing mode of the icon on the display (with the image of a clock). Then the driver briefly presses the button with the star icon to move the cursor to the icon with the text “turbo”.
3. To confirm switching on, you need to briefly press the key marked with a locked padlock icon. The external lamps on the car will turn on, the key fob will sound a double signal with a buzzer, and then play a melody. The icon with the text “turbo” remains active on the display.

To activate the mode on the A93 alarm, you need to move the cursor to the icon with the text “turbo”, and then confirm the choice by pressing the button equipped with a red rubber cover.

After the buzzer sounds, the programmed operating time is displayed on the display, which allows you to adjust the value.

Once the mode is activated, the turbo timer is automatically turned on when the parking brake lever is lifted and the key is removed from the lock. After locking the door, the operating time is displayed on the remote control display; after activating the security mode, an icon in the form of a cloud of exhaust gases is shown on the screen.

How to setup

To program the engine operating time in turbo timer mode on the A91 alarm system, you must enter the complex setup mode by pressing the special button 6 times. After activating the ignition support circuits, the siren will sound 6 times, indicating that the alarm is ready for configuration. The driver selects the function by pressing the setting button once. After the siren gives a signal and the control diode flashes, the value of the motor operating time is selected, the programmed parameter is shown on the display.

The Starline A93 turbo timer is configured immediately after turning on the “turbo” icon; short presses on the red key allow you to change the operating time in a circle. Once the desired parameter has been configured, the value must be written to memory. The process ends automatically if the owner does not operate the buttons for 4 seconds. Forced recording is allowed by holding down the round button on the remote control. After the beep sounds, the key is released.

How to disable

The car owner turns off the turbo mode by selecting the mode icon on the display using the cursor method. After the turbo timer on the alarm is turned off, the icon with the inscription “turbo” goes off on the screen. The programmed time is stored in the memory of the central unit of the complex, allowing the function to be used when the mode is reactivated. It is impossible to completely remove the turbo timer from the Starline security system.

Principle of operation

How to turn off the turbo timer on Starline A93
The turbo timer provides support for the operation of a gasoline or diesel car engine at idle speed after removing the key from the lock. The reduced rotation speed ensures a smooth decrease in the temperature of the turbine housing and exhaust manifold, increasing the service life of the unit. Additional cooling is provided by circulating liquid. The owner of the car sets the operating time of the power plant during setup. After the timer is reset, the engine is turned off, and the ignition support circuits are included in the security zone.

Advantages and disadvantages of the mode

Advantages of using a turbo timer:

• provides cooling of the supercharger without the presence of the driver;
• increases the service life of the turbine rotor;
• provides protection for the vehicle when the power unit is running.

Design disadvantages include possible conflicts between the standard security system and additional electronic units. To ensure the operation of the power unit, it is necessary to install immobilizer bypasses. Changes in the vehicle's electrical circuits cause the vehicle to be removed from warranty service.

Varieties

There are 2 modifications of the device mounted on cars:

• Self-contained unit equipped with a separate microprocessor. The product is connected via additional channels to a previously installed alarm system or integrated into a standard security system.
• A device implemented in software in a security system. A control panel with a display is used for setup and control.

Operation logic

The turbo timer allows the engine to continue idling after the key has been removed from the ignition. The device is used in internal combustion engines equipped with turbocharging. It does not matter whether gasoline or diesel is used as fuel. Under heavy loads and prolonged operation at high speeds, the turbocharger becomes very hot. During operation, engine oil is used for cooling, and in some turbines, coolant is used. Once the engine is stopped, oil circulation stops. Therefore, if the temperature in the channels is too high, the oil burns, which leads to the formation of carbon deposits. When the turbine resumes operation, the burnt oil will act as an abrasive, grinding down the surfaces of the rubbing parts. In addition, deposits reduce the cross-section of the oil channels, thereby impairing the supply of lubricant. The logic of the turbo timer is to let the engine run for a few more minutes after stopping in order to cool the turbine. At the same time, you can safely lock your car and go about your business. The engine will stop after the programmed time.

Feasibility of installation

A turbo timer is most often installed on a diesel engine only due to the more frequent use of turbochargers in conjunction with. In what cases is it advisable to install this accessory:

But even in this case, strong arguments can be made against installing a turbo timer:

• a diesel or gasoline engine is used for measured city driving with infrequent loads. Even if from time to time you have to actively pedal, then a quiet ride at up to 2000 rpm, even 1 minute before stopping, is enough to cool the turbocharger of a modern car. It would be useful to remind you of the high requirements for motor oil, which should be poured into turbocharged engines;
• The car has an alarm system with a turbo timer function. In this case, installing a separate device will be a waste of money. The alarm functionality can be viewed on the official website of the security system.

DIY installation

Please note that installing a turbo timer on a car equipped with a standard alarm system, with control over the main components via a CAN bus, and also equipped with a modern security system, will be an extremely difficult task. You will need skills in reading electrical diagrams, as well as understanding the logic of the operation of the main electronic systems of a car.

If you make an unqualified connection yourself, there is a high risk of a conflict between the systems, which can lead to the appearance of various “glitches,” the Check Engine coming on, and a weakening of the level of protection of your car against theft.

For the design of the device, it does not matter whether the turbo timer is installed on a diesel or gasoline engine. The difference in connection will largely concern only the power supply for the service functions of the device. The connection logic will differ depending on the specific car model and turbo timer. When purchasing a device from reputable manufacturers (HKS, Apexi, Greddy, TT, Blitz, TTX), in most cases you receive:

• Control block;
• module with a screen for demonstrating time reporting and other service functions;
• wires and connectors for connection;
• instructions.

Installation

To install the kit on your car, you will need:

• pliers that can be used to cut the wire and crimp the terminals;
• male-female terminals. You will also need a bolt terminal for ground, if one is not provided in the kit;
• heat shrink for reliable insulation of joints;
• clamps for fixing wires;
• screwdrivers and other tools necessary for assembling/disassembling the interior.

Do-it-yourself installation begins with de-energizing the on-board network (disconnect the negative terminal of the battery). You need to remove the interior plastic blocking access to the ignition switch contact group. To install a turbo timer on diesel/gasoline, you need to “cut” into the wires coming from the ignition switch. The module, which is often supplied with double-sided tape, can be secured in a convenient place near the device. The same method is suitable for mounting the control unit, which can be located inside the dashboard. If possible, it is better to additionally secure the block and wires with ties to avoid further extraneous noise when driving over uneven surfaces.

Alarm with built-in turbo timer and its selection

Esud: what is it in a car

The function of a timer that keeps the engine running can be performed by a car alarm. Therefore, now, in 2021, few people purchase a turbo timer made as a separate device. Let’s say the instructions supplied with the equipment contain the following diagram:

Wiring the main connector of a car alarm

As you can see, there is a diode inside the main module. This means that it is included in the ignition circuit wire break. We are talking about a variant of the circuit designated by the letter “A” in chapter “1”.

In the manual for the equipment of another model, everything looks different. Here is shown the wiring of a connector equipped with 6 terminals:

Power 6-pin alarm connector

The wire in green insulation allows current to pass, bypassing the lock terminals. At the same time it is a “control entrance”. The wire indicated in the diagram is connected in a T-shape, and the breaking points, if you do not take into account the presence of “blocking”, are completely absent here. None of the schemes presented in the first chapter can be implemented with such a signaling. It’s good if in this case they suggest using a “semi-automatic”, otherwise you will have to be content with the option discussed in “Chapter 3”.

Technical side of the issue

Whether or not it’s worth installing this device on your car is up to you to decide, of course! However, there are a number of pros and cons to installing a turbo timer. So, the technical side of the question is why everything is worth installing.

The thing is that turbines, which operate on the energy of exhaust gases, become very hot during operation. Especially if you drove at high speeds - then the flow and temperature of the gases is very high. In this case, temperature has a negative effect on the impeller bearings - because if you suddenly stop working, they are no longer lubricated by engine oil, and oil residues can burn at the points of contact. Which leads to “coking” of the oil outlets from the turbine - and costly repairs are not far away. It is because of this that the oil in a turbocharged engine should be changed more often.

Installing a turbo timer prevents the engine from stopping abruptly; it runs for another 3–5 minutes before stopping, at low speeds. The temperature drops significantly (or, as many people write, cools) to an acceptable temperature - the oil no longer burns at the points of contact, and the “impellers” are much cooler (so to speak).

That is, to summarize, the turbo timer first of all prolongs the life of the turbine itself, as well as the engine oil. It’s worth thinking about, in principle, the gadget is necessary.

But on the other hand, if you don’t drive very hard, and don’t turn the engine up to 5 – 7000 rpm, drive at 2000 – 3000, then you may not need such a device.

Also, many manufacturers have now changed the design of the turbine - the exhaust gas chamber does not greatly affect temperature fluctuations in the bearings, as well as in the oil-conducting tubes.

YES, and it’s not very convenient - when you just drove the car into the garage or drove it from one place to another in the parking lot, and it still works for a few minutes. There is also a slight excess fuel consumption here.

That is, it’s as if you don’t need to install it. In any case, it's up to you to decide. I recommend surfing the forums for your brand, and also asking questions at the dealership.

Pros and cons of a turbo timer

Gas equipment for diesel: how realistic is it?

This small electronic car gadget has a number of undoubted advantages. The most significant of them include the fact that he:

• Avoids overheating of the turbine;
• It is relatively inexpensive;
• Installs easily and simply;

As you know, an automobile turbine is a rather complex and expensive unit. If its bearings fail (which very often happens with constant overheating), then they themselves and their replacement cost quite a substantial amount. If the turbine turns out to be beyond repair, then the costs become even more significant. A turbo timer costs a much more modest amount. As for the installation of this device, it is quite possible to do it yourself, although it is better to entrust this matter to professionals.

However, turbo timers have one significant drawback. It lies in the fact that they quite often conflict with standard car alarm systems. As practice shows, in most cases this problem turns out to be completely removable if professionals get down to business.

Recommended option for cars with one ignition circuit

Two schemes have been considered, and now another one will appear. It shows how to connect a semi-automatic timer:

Connecting a semi-automatic timer

The relay shown in the diagram can be placed by the manufacturer together with the turbo timer electronics in the same housing. Then the connection diagram will look simpler (Fig. on the right). The switch that switches the “zero potential” is a micro-button for the handbrake or a separate button in the cabin. Its presence is mandatory.

Let's consider the algorithm of operation of semi-automatic timers:

• As soon as the key is turned to the IGN position, the relay is activated and the corresponding indicator on the console lights up;
• To open the relay contacts, you need to activate the countdown. This action is performed by closing the microbutton contacts.

Let's imagine a non-standard situation: the handbrake is applied, the driver turns the key to the IGN position and then turns off the ignition again. Then, after the time preset in the settings has elapsed, the relay contacts should open. In general, during the operation of the “semi-automatic”, no situations will arise that lead to unexpected consequences. But it is recommended to remain attentive.

Typical turbo timer connection diagrams

Imagine that the driver stops the car, turns the key to the OFF position, and the engine does not stall, continuing to run for several more minutes. Here we consider the actions performed when operating automatic turbo timers. In fact, there are still “semi-automatic” machines. They are somewhat more difficult to operate: when the car is not moving, you need to remove the key from the lock, and then you need to activate the handbrake. If this is not done, the engine will not stop until the fuel runs out. Simply, the “semi-automatic” must receive a command to start counting the time, and this is done by closing the handbrake microbutton.

A method that is best not used in practice

It would seem that the role of a turbo timer can be played by a certain module connected to terminals “30” and “15” by a pair of wires. As soon as the voltage is lost at pin “15”, the relay built into the module will close the two wires together, and the current in the circuit will be restored. The switch that activates the countdown start is not used here. The current in the circuit disappears for a short time, and then it appears again.

Not every engine is designed to have the main ignition circuit open periodically. In reality, this is what you can see:

• A turbo timer designed according to the principle discussed here works as expected in 30-50% of cases;
• In other cases, the relay also works reliably. But the motor, not designed for the loss of a spark, manages to stall before the timer contacts begin to pass current.

Draw conclusions.

Understanding the ignition switch terminals

It would seem that if you can implement an automatic timer option, then why talk about “semi-automatic machines” at all? In fact, a semi-automatic timer can be easily connected to any car, but the same cannot be said about an “automatic” one. Look at the diagrams below:

Connecting a turbo timer in different cars

Here we show you exactly how to connect an automatic timer. Let's say that the presence of two ignition circuits (IGN and IGN2) is not provided for in the car circuit. Then you can’t do without installing a diode. The diode itself, shown in diagram “A,” must pass a significant amount of current, while the voltage drop across it should preferably be kept to a minimum. In practice, selecting such a part is not easy.

The ignition switch terminals are usually designated as follows:

• 30 – contact to which voltage is applied all the time;
• 2 – terminal connected to pin “30” when the key is in the ACC or IGN position. Through terminal “2” the current flows into the power supply circuit of the accessories;
• 50 – starter contact, receiving the potential “+12 Volts” when the key is brought to the START mark;
• 15 – terminal of the main ignition circuit. It closes with contact 30 when the key is turned to the following marks: IGN, START;
• 15/2 – terminal of the second ignition circuit. The positive potential is located on it when the key is turned to the IGN mark, but not START.

Everything should be clear here.

Simple DIY turbo timer - DIY Community on DRIVE2

There was nothing to do, and my friend asked everyone to help him with the manufacture of a simple turbo timer for a VAZ with a turbine. It’s clear that you can buy the whole thing, but a friend wanted a version that is invisible, so that nothing hangs on the dashboard). Yes, I needed to do it myself a long time ago, and I adhere to exactly the same philosophy - nothing superfluous on the dashboard). Once the thoughts come together, it means it needs to be done.

It was decided to do it on the STM8S003F3P6

. Why not ask at ATTINY13? It’s simple, because STM8S is cheaper this time, more memory means two, more outputs/inputs means three, and I bought a lot of them, so that’s four)))

Relay used HLS-T78-DC12

. The maximum switched current is 10 Amperes, which is enough to operate the ignition circuit IGN1 (15\1).

Work algorithm

very simple and tied to a handbrake. We arrived, raised the handbrake, the timer was activated after 3 seconds and the turbo timer relay turned on. To set the operating time, there is a separate input to which you can connect a momentary button that is connected to ground. Or you can not connect anything, but once set how much we want the motor to work and that’s it. So, we raised the handbrake, the timer activated, and took the key out of the ignition. That's it, after the set period of time has passed, the ignition will turn off and with it the device - the turbo timer - will be completely de-energized. If we allow the car to be released from the handbrake while the engine is running on the turbo timer, the engine will immediately stall.

The time intervals specified during setup are 30 seconds, 1 minute, 1.5 minutes, 2 minutes, 3 minutes.

That's the whole description. I am attaching files to the article for review. Don't forget to indicate authorship and share with people too)

PS\ Yes, all this can be bought in China, but if someone likes to assemble something with their own hands, then why not... And the price tag for the list of radio components for this project is 10 times lower than the cost of the Chinese one) As they say - to each his own!

Starline with a turbo timer: how to set up, enable and disable the turbo timer on an alarm system

Manufacturers of modern cars, in order to increase engine power and reduce emissions of combustion products into the atmosphere, are increasingly using turbocharging technology. The main disadvantage of the development is the clogging of gases and oils in the turbine as a result of its overheating during operation. Connecting a turbo timer helps to avoid costly repairs.

A turbo timer is understood as a certain device or function as part of a car alarm that keeps a turbocharged engine running at idle speed after the car's ignition is turned off.

When the optimum temperature is reached, the engine automatically stops.

However, this function is not supported by all alarm manufacturers.

The leading brand is Starline with a turbo timer already built into the alarm unit, which does not require the installation of additional elements.

The need for a turbo timer

The operation of a turbocharged engine is based on turbocharging, which, during intensive use of the vehicle, can increase the temperature of the exhaust system elements to 800°C.

During movement, the role of coolant is played by engine oil circulating through the engine components.

This is why it is important to leave the engine running for a few minutes after stopping it.

In order not to forget about this small but important part for the proper operation of the car, it is recommended to install a turbo timer

Types of turbo timer

The turbo timer can act as an independent element, which is a unit installed under the torpedo with a connection to the ignition switch. Or maybe as part of the Starline car alarm system. The latter option is considered the most convenient, since it does not require synchronization of the alarm and turbo timer, minimizing the risk of security system failure.

One of the first alarm systems released that included a turbo timer, Starline A9, became an indispensable assistant for car enthusiasts for a whole decade. Later, new, improved models began to appear - Starline B9, B6, C6, A 62 and A 92.

All of the company's lines also provide additional functions. For example, the Starline alarm system with turbo timer and auto start is available in modern models E 90, A 91, A 94, B 94 and D 94. This combination helps not only to reduce the cost of installing individual systems, but also to make life easier for motorists in the winter.

Setting up the turbo timer

After installation work, it is recommended to check the serviceability of the function and make the necessary settings. The turbo timer is configured according to two parameters:

1. depending on the desired engine idling time;
2. depending on the temperature of the turbine assembly.

Despite the uniform principle of operation, there are some nuances in how to set up the turbo timer. Even models from the same line may have differences in settings.

For example, programming a turbo timer on an early model Starline a61 key fob does not require a self-set time parameter. After a certain algorithm of actions, the turbo timer operates in automatic mode for the period specified by the specialist. The turbo timer on the Starline A91 alarm key fob is programmed in the same way.

Later models of the A line are equipped with the ability to independently select the engine operating time after removing the key from the ignition. Thus, programming Starline A93 using the service buttons of the key fob allows you to configure the turbo timer mode for a period of 1 minute. And the settings of the Starline A63 car alarm allow you to start the turbo timer for up to 4 minutes.

Activating the turbo timer

After the settings have been made, it is possible to activate the turbo timer in three different scenarios:

1. automatically after applying the parking brake and turning off the ignition;
2. using the key fob after applying the parking brake, locking the doors and turning on the security mode;
3. after applying the parking brake.

A car enthusiast can choose how to turn on the turbo timer on Starline, based on the preferences and degree of convenience of each option.

For example, on older generation alarm systems, like the Starline A94, there is no way to independently program the duration of the turbo timer, so it would be more convenient to remove the key from the ignition and activate the security mode.

Often the instructions do not indicate how to disable the turbo timer. It is assumed that disabling a mode is similar to activating it, but in reverse order.

If the function is not needed, it is enough to deactivate the icon indicating the turbo timer using the service buttons of the key fob.

Disadvantages of using a turbo timer

How to disable the turbo timer on the starline a93 alarm system
If you have an irresistible desire to install such a controller, then you should first prepare for several possible problems, and one follows from the other. If you install a turbo timer, it turns out that after the car owner leaves the car and goes about his business, the engine controlled by the sensor will remain active for some time. If an attacker notices this feature of the vehicle, he can take advantage of these few minutes and get into the car without any problems.

This leads to the next problem - you need to configure the device so that it interacts harmoniously with the car alarm. If we are talking about the simplest security system, then it is assumed that as soon as the car goes into security mode, the engine should stall. Therefore, you will have to either completely replace the alarm module (and everyone knows that this is not an easy matter) or purchase additional devices in order to “make friends” of the turbo timer with the system.

And here the third problem appears - warranty service. If the car owner independently decides to “redesign” the security system, then he thereby violates all the conditions for using the equipment. Therefore, if he connects something incorrectly and disables the entire unit, he can easily be denied free repairs or maintenance. The same applies to owners of cars under warranty, which provide the ability to connect a turbo timer. In this case, the installation of the device should only be carried out in a service center that has been certified by the car manufacturer itself. Otherwise you will have to blame yourself.

If all warranty periods have long expired, and there is an urgent need to install such a module, then you can try to install it yourself.

How to turn on the turbo timer?

The countdown timer on an automatic or manual transmission can be activated automatically or by command.

Starline A9

Activation is done as follows:

1. The car engine turns off.
2. Button 1 on the remote control is pressed. This control is held until the hazard warning system beeps three times and the communicator sounds a melody.
3. The Turbo icon will appear on the key fob display, as well as the timer operating time.
4. The car engine will run for a few minutes and then turn off.

Starline B9, A91

The turbo timer on these models is activated as follows:

1. The parking brake is activated.
2. The key is removed from the ignition switch, after which the driver must leave the car and close all doors.
3. The LED indicator of the car will start to light constantly, the side lights will flash once. The key fob will emit a melodic signal, and an icon in the form of “r01”, “r02”, “r03” or “r04” icons will be displayed on the screen.
4. The first button on the key fob is pressed. The vehicle will beep once and the side lights will flash once. The ignition zone protection, shock sensor, and additional controllers will be turned off. If the locks are connected to the alarm, all doors will close.
5. The key fob should emit a short beep. Icons will appear on the communicator screen, symbolizing the armed mode and the running engine.

It is important to know

As long as the TURBO icon is displayed on the screen, the turbo timer function will be activated automatically.

Starline A92, A93, A94, E91

On these models, the method for activating the function will differ depending on the selected ignition support method:

1. Auto. To enable the function, you need to lift the handbrake lever on the car and set the gear to neutral. If the vehicle is equipped with an automatic transmission, you must select parking mode P, after which the engine stops.
2. From the remote control. In this case, you need to close all the doors, and then press the second button on the key fob.
3. Using the parking brake. The option is activated by raising the handbrake.

It is important to know

When setting the turbo timer, make sure that the car is in neutral gear. All actions to configure the function must be carried out with the engine running.

After the settings, the engine operating time before stopping will appear on the communicator screen. You need to remove the key from the lock and activate the vehicle protection mode.

Starline A61

In cars with a Starline A61 alarm system, the turbo timer is turned on as follows:

1. The parking brake on the car is raised. The diode indicator should work, and the engine operating time after shutdown will appear on the remote control screen.
2. Within 30 seconds, the user removes the key from the lock and leaves the vehicle.
3. All doors are closed, as well as the hood and trunk of the car.
4. The first button on the remote control is pressed. The communicator should sound a melodic signal, and the car's alarm system will blink once.
5. The protective function is activated, the car doors are locked and locked.
6. After a few minutes the engine will stop running.

Video: setting up the Starline A93 timer

The Gizma channel in its video talked about the nuances of activating and controlling the turbo timer function on cars with a Starline A93 alarm system.

Disadvantages of installing a turbo timer on a diesel engine

In addition to all the advantages for car owners from installing a turbo timer, there is also a downside to the coin. The fact is that it is almost impossible to correctly combine this device with a standard car alarm, since when you remove the key from the ignition, the engine stalls by default. For its further operation, another channel is required, which is available only on the additional alarm system. So the car owner will have to purchase not only a turbo timer, but also a new anti-theft system.

But by installing a non-standard alarm system, the car can be retrofitted with an autostart system. This is a very convenient thing for those who are used to saving time, since, upon leaving the house, you can get into a car that has already been warmed up.

Another difficulty for those who want to install a turbo timer on their new diesel car may be the position of the car dealership where the car is under warranty. The fact is that most automakers categorically do not recommend installing a turbo timer, because it is not one of the original spare parts. Therefore, after installing this device, the car may simply be removed from warranty.

Device selection

Before starting installation, you need to decide on the manufacturer of the turbo timer. The following performed best on the market:

The equipment is also important. For example, by purchasing an alarm system with a Starline or Magicar turbo timer, a car owner can expect to receive:

• Control block;
• a display that displays the time before the engine turns off and helps to configure the turbo timer;

Most turbo timers are installed under the dashboard. This is done not only for aesthetic purposes, but also to hide the device from prying eyes, since it has an alarm function. If there is a pre-installed security system, this criterion is not so relevant.

Feasibility of installation

It is most advisable to install a turbo timer in the following cases:

• A turbocharged diesel engine is installed in an all-terrain vehicle, primarily used in off-road applications. The operating mode is predominantly harsh. Often you have to drive with the maximum permissible load and with no cooling by the oncoming air flow;
• The decision to install a turbine on an atmospheric engine was made independently.

Installing a turbo timer seems less relevant in the following cases:

• Gasoline or diesel engines are used in a gentle mode. Movement occurs mainly around the city. The driving style is far from dynamic. Before stopping, the speed rarely exceeds 2000. The power plant uses high-quality oil;
• The car already has a car alarm with a turbo timer, for example, Starline. Installing an additional device will be unnecessary;
• The car is under warranty and installing additional equipment will lead to its loss. In this case, you need to get advice from a car dealership about the possibility of installing the device.

What is a turbo timer?

First, let's look at what a turbo timer is in the Starline a93 alarm system, let's try to explain it in simple words.

Imagine a running car engine. This is, for a moment, his most important unit.

Therefore, it is important to handle it as carefully as possible, without avoiding auxiliary options to prevent its rapid wear. This is exactly what turbo mode is.

When the engine is turned off, a sharp temperature jump occurs - from hot to cold. Not the most useful procedure. The turbo mode allows you to gradually cool the engine, maintaining its operation after turning off the ignition at idle (without load on the engine).

How it works?

• The driver parks and initiates the activation of the turbo timer on the Starline A93 using the key fob;
• Next, he turns off the engine and leaves the car;
• He puts the car on guard and calmly leaves;
• At this time, the engine continues to idle.
• Air will circulate inside the unit, which will ensure a smooth decrease in its temperature;
• After a set time interval, the system will stop the motor.

There are 2 types of turbo timers: autonomous and built into the signaling system.

1. Autonomous - separate modules that are installed near the main console of the car. They are connected to the alarm system through additional channels. Find out how to set them up and program them in the instructions for your security kit.
2. Built-in – logically, they are included in the alarm package and are one of its additional functions.

Installation of an autonomous turbo timer on Starline A93 takes place in a specialized service center

If you do not have high-quality knowledge and, importantly, do not have experience in the field of alarm installation, we do not recommend doing it yourself. You risk causing problems in the functioning of both the security kit and the electronic modes of the machine itself

For the stubborn, however, we will briefly explain how to install a turbo timer on a Starline A93 alarm system:

The turbo timer must be configured for the 2nd additional Starline channel. The red-yellow wire on block X3 of the signaling system unit is responsible for this channel. Connect it to the timer according to the diagram from the system instructions. We repeat, if you do not have at least minimal knowledge in the field of automotive electronics, it is better to entrust this work to professionals.

But it’s much easier to configure an already installed module yourself.

Let us remind you how to configure the turbo timer on the Starline A93, we told you at the very beginning of the article.

Turbo timer for diesel: to use or not?

Many must have noticed that recently more and more cars that run on diesel fuel have begun to appear on the roads.

The reason for this is simple - more optimal use of fuel, because its consumption, most often, in a diesel engine is noticeably less than in a gasoline engine.

But practice shows that diesel engines are usually inferior in power to their gasoline counterparts. That is why the turbo timer for diesel began to gain popularity - a fairly simple device that helps the engine continue to operate even at idle speed.

But is it needed at all? We will try to figure this out in our article.

Connection, configuration, disconnection

Let's consider the connection using the example of StarLine A93 - since this alarm is based on a common modular platform, in other modern models the functioning and settings of the turbo timer are similar.

To control the turbo timer, use flexible programmable channel 2 - yellow-red wire on connector X3. When the turbo timer is activated, a ground will appear on this wire, which turns on the ignition support relay or duplicates the signal of the Start-Stop button. If the work of the immobilizer crawler is necessary, it is connected to the terminal intended for this purpose (pink wire of connector X3).

After turning on the circuits, all that remains is to configure the alarm functions. They are configured via the main key fob:

1. Disarm the vehicle and quickly press the Valet service button five times.
2. Turn on the ignition.
3. The key fob screen will display AF (alarm settings).
4. Enter the AF menu by pressing button 3 long until the beep, then briefly.
5. Further presses on button 3 will move to function 14, which by default is set to 14-1.
6. By pressing button 1, set the new function value: 14-4. Channel 2 is now configured to control the turbo timer.
7. Long and short press button 3 again to exit to the main menu.
8. Press 3 to select the SF (autorun functions) menu.
9. Enter this menu by long and short pressing 3 again.
10. Go to function 1 and set it to 1-1. Otherwise, the turbo timer will not turn on.
11. Go to function 11 to set the principle of monitoring the operation of the engine (if, after turning on the turbo timer, the alarm does not detect that the engine is running, then the ignition duplication will stop). This only needs to be configured with an analog connection, if the alarm is not connected to the vehicle's CAN bus or does not read engine speed from it. Option 11-1 sets control by voltage in the on-board network and is available without additional connections, in options 11-2 and 11-3 connect to the signal output of the generator, 11-4 sets control by tacho signal (connection to an analog tachometer or to injectors).
12. Go to function 12 to set how the turbo timer is activated. In option 1, ignition interception occurs every time the driver pulls the handbrake and turns off the ignition. This method does not always work, since there is a short pause between turning off the ignition and turning on the turbo timer - the engine may stall before the turbo timer turns on. In this case, use option 12-3: ignition interception will occur immediately when the handbrake is pulled if the engine is running. In option 12-2, activate the turbo timer manually by pressing button 2 on the key fob until the engine is turned off. This is more convenient in winter - you don’t have to leave the car on the handbrake, risking it freezing. In option 12-4, ignition interception will be disabled and the turbo timer will not be operational.
13. If the turbo timer requires an immobilizer bypass to operate, go to function 13 and set it to option 13-3.
14. Turn off the ignition.

Turbo timer for diesel. Schematic diagram and principle of its operation

The circuit is implemented on a single transistor. The transistor KT 816B was chosen, I think any of this series will do. The turbo timer works according to the following algorithm. When the engine is running, transistor VT1 is closed by applying a positive potential from the ignition switch to the negative terminal of the capacitor, as well as to the base of the transistor through resistance R1. After turning off the ignition, the positive potential disappears accordingly. Current begins to flow in chains R2-R1-C1. This current is enough to open the transistor. In this case, the current passing through the transistor (emitter - collector) powers the relay winding, which immediately turns on. That is, when the power from the ignition switch is lost, the relay turns on. The transistor will remain open until the capacitor is charged. After the capacitor is charged, the current through resistance R1 will not be enough to open the transistor. Accordingly, the collector-emitter current will disappear and relay P1 will open. That is, the relay will work while the capacitor is charging. At the ratings indicated in the diagram, the delay time for turning off the engine will be about 50 seconds. By increasing the capacitance of capacitor C1, you can increase the delay time, decreasing it, and reduce it. The time can also be increased by increasing the value of resistor R2. You can increase the resistance to about 15 - 20 K; a further increase will weaken the current on the capacitor so much that it will close the transistor. A feature of the circuit is the fact that when the engine is restarted within 1 - 2 minutes, the capacitor will not have time to discharge through resistance R1, and accordingly the relay will not turn on again. If I may say so, the return to operation of the circuit occurs approximately 10 minutes after the engine is started.

Transistor used in the turbo timer circuit

Now I would like to talk a little about the modes taken when testing this turbo timer circuit for a diesel engine. They will be presented in the form of tables.

Table 1. Turbo timer supply current under various operating modes

When the current drops to 40 mA, the relay winding does not have enough magnetic field strength to hold the relay contacts and it opens. The table also shows that the current in standby mode will be about 7 mA, which will not affect the discharge of your battery.

Table 2 Relay delay time at different times from the moment of the last stop to the diesel engine start.

The table shows that the time to restore the circuit's functionality is about 10 minutes.

In some cases, when installing a turbo timer on a car, the following phenomenon was observed. Due to a voltage surge, that is, when it dropped due to the generator being turned off, from approximately 14 to 12 volts, the transistor opened again and the relay turned on accordingly. As a result, the engine managed to catch up and tried to start again. We can say that the effect of a pulse interruption of stopping the engine and its subsequent starting was observed. After installing the stabilizing microcircuit on the emitter of the transistor, by powering it through the KREN microcircuit. The scheme began to work stably. The connection diagram for the KREN microcircuit is given in our other article, “Voltage stabilizer in a car on a microcircuit.”
