Front bumper of the Daewoo Nexia N150 model: structural features and tuning

Chip tuning of the Daewoo Nexia is a change in the software (chip, firmware) of the electronic engine or transmission control unit to increase power, reduce fuel consumption, eliminate failures, and ensure stable operation of the engine control system.
All models with petrol, diesel and turbocharged engines are available for chip tuning. For tuning we use software from leading Russian developers: Paulus chip, ADACT, Ledokol.

The proposed chip tuning software is intended for use on ordinary (non-sports) cars without the goal of obtaining maximum power and torque, without reducing the service life of the units.

You'll get a well-balanced increase in power and torque not only at high rpm under full load, but also in the low and mid-range, without increasing emissions.

After installing the modified software, improved driving characteristics can satisfy even the most demanding car owners. Vibration disappears at idle, jerking when driving in traffic jams, excellent acceleration dynamics appear. When the air conditioner is turned on, the loss of engine power is significantly reduced.

The firmware is focused on driving comfort: elimination of factory software errors, flexibility, reliable starting at any temperature.

In addition, it is possible to eliminate errors due to non-functioning oxygen sensors (lambda probe), remove the software catalytic converter (catalyst), and also transfer the car to Euro 2 econorms.

The appearance of error codes P0130, P0131, P0132, P0133, P0134 and other errors associated with a faulty lambda probe, catalyst errors P0420, P0421, 0422, P0423, P0124, P0430 can be eliminated forever with the help of reprogramming and without compromising the driving characteristics of components and units. The warranty for the operation of the modified software extends to the entire service life of the vehicle, that is, indefinitely.

All work is done without interfering with the car's electrical wiring, without soldering in microcircuits and chips, only by replacing the software while maintaining the factory warranty. For each car, a certificate is issued with a unique authentication code, which can be verified on the software developer’s website.

Appearance

Many motorists begin tuning the Deo Nexia not with improving technical characteristics, but with transforming the exterior, which involves installing body kits, spoilers, tinting and other parts. Installing all this completely transforms the vehicle and slightly improves dynamics (by increasing aerodynamic performance).

All work on tuning the appearance of the car can be carried out in your garage, without giving money to the craftsmen in service centers. You just need to buy new bumpers, spoilers and side sills, and install them instead of standard body parts using a set of regular wrenches and screwdrivers.

Headlight tuning

Tuning standard Deo Nexia headlights is popular. For example, instead of them you can install lensed bi-xenon blocks, and move the side lights to turn signals. In this case, washers can be additionally installed in the bumper. The rear lights are tuned using the same principle. You can also use another tuning method, which involves tinting the rear light glasses using a special film or varnish.

Installation of deflectors

Deflectors on the hood and side windows give the car originality and make it more elegant. In addition, these accessories add practicality, since after installing them on the side windows, you can lower the windows in rain and snow, ventilating the interior and preventing fogging.

As for the so-called fly swatters (hood deflector), they do not affect the dynamics, but make the appearance of the Deo Nexia more aggressive. In addition, in this way you will protect the hood from small chips and other damage from stones and spikes flying out of the wheels of cars in front.

This is not JDM: tuning Daewoo Nexia

Standard introductions

Do you need a car that would be very inexpensive to buy, would not break down, and would cost a penny to maintain?
And so that at the same time it drives relatively dynamically and is quite comfortable for two people? “It doesn’t happen like that,” you say. "Happens!" – the hero of our today’s material is sure. However, there are a few “buts”: you will have to sacrifice pathos, the legendary status of the brand, high-quality Mexican jerboa leather in the cabin, iPhone support and a host of other fashionable gadgets and options that usually begin the description of almost any modern car. Ilya was guided by approximately these considerations in 2009, when the time came to change his means of transportation. It’s worth noting that he already had experience in motorsport (professional karting, Legends, RSKG), so I wanted driving a city car not to cause nausea and despondency, but to delight with drive.

Of course, with such requests, further improvements to the selected vehicle were also expected, but with all this, the purchase budget was quite modest. As a result, after looking at several options, Ilya settled not on an elderly Japanese car like the Mark II, as is often the case, but... on a Daewoo Nexia.

Since I immediately planned to begin modifications, I bought a new Nexia in the simplest configuration.
I had encountered this brand and model more than once before, and had a full understanding of its capabilities and shortcomings. I chose a copy without power steering, air conditioning and other joys of automobile life. She doesn’t need this - nothing should take away from the already modest engine power (80 hp), and this will only affect reliability for the better (the Nexia’s air conditioning and electric windows are known problem areas) Ilya

Seats

UNP Racer

First of all, the front seats went to the trash bin - their place was taken by civilian UNP Racer “buckets”. Moreover, for the passenger, the lower part of the “seat” was adjusted to make it convenient to get in and out of the car. Then came the turn of the suspension: Weitec springs (-40 mm), KYB AGX shock absorbers with adjustable stiffness, a larger-diameter front stabilizer and an upper strut were installed. Instead of standard wheels, they installed 15-inch VSMPO forged wheels with Yokohama AVS V 102 tires.

After that, it was the turn of the transmission. Instead of the standard gearbox, they introduced a box with a short main pair and other gear ratios - also from Nexia, only a different version. While looking for tuning options, Ilya even read somewhere that someone installed an Opel Calibra gearbox in a Daewoo, but the gear ratios were longer, so he didn’t see the point in this decision. But together with a different gearbox, a clutch of increased diameter was installed.

Brakes

front discs and pads

ATE

Having finished with the transmission, we inspected the brakes, selected ATE discs and pads (standard discs were prevented from overheating) and slightly modified the main brake cylinder. Considering that after restyling the Nexia is equipped with more powerful calipers, they were not touched. At the moment, the driver is generally satisfied with the brakes, although there are already plans to increase the performance of the rear ones.

Now about the engine. On occasion, Ilya received a sports camshaft from OKB Dynamics SmartCAMS, which was immediately introduced into the engine along with a modified throttle and minor modifications to the cylinder head. The standard exhaust went to the trash bin after the seats - its place was taken by a system from MG-Race (a spider, two resonators and a muffler), after which the engine was chip-tuned. The ECU remains standard, but it works with an individual program even after online configuration.

Not only fast, but also beautiful and convenient

The modifications made eventually led to the fact that we had to pay attention to the body, the rigidity of which, to put it mildly, raised questions. At the front, we simply installed a lower stiffener strut (without it, the strut cups would “walk around”). But at the back we had to do a little more difficult work...

Tires

semi-slick tires

TOYO R888 195/50/15

For normal operation, it was necessary to trim the inner edges of the rear wings and change the shape of the wheel arches. And all again because historically Daewoo Nexia is a deep modernization of the Daewoo Racer, a licensed copy of the Opel Kadett. Someone, while developing the Kadett, came up with the idea to make a very unique rear arch that covers part of the wheel and is made in such a way that it is very difficult to simply cut it out without damaging the body. And UzDaewoo continued the idea and made even tighter wheel arches. As a result, the rather narrow 195-mm tires on the new Nexia, during active driving, touched the inside of the wheel arch and the edge of the wing, forcing everything to be redone.

In addition to technical improvements, Ilya paid a little attention to the interior of the car. Instead of the uncomfortable steering wheel, I installed a Momo, and replaced the supposedly stock double-din Clarion with a regular JVC with Morel Tempo acoustics.

Personally, I find it very comfortable in the car.
The conditions of the “working space” are such that I can easily drive a Daewoo Nexia over long distances, about 1,000 kilometers, and not get tired at all. As a result of all the alterations, the result was a car that fully suits my driving style. After the KZ-2 series karts (with engines up to 125 cm³ and six gears), I am absolutely not surprised by the incredible acceleration to “hundreds”, and I am not chasing this. It is important to me that the car can drive and at the same time be stable in “combat” mode, that is, brake late and without horror, turn accurately and predictably on the verge of slipping where necessary, and accelerate normally. That’s why I made the suspension stiffer, introduced a “short” gearbox, installed Slik forged wheels with TOYO R888 semi-slick tires, and so on. I thought a lot about a limited slip differential, but ultimately abandoned the idea due to concerns about the life of the unit. Of course, in the city there are few places where I can use the potential of my Nexia, but I wanted to create just such a config Ilya

When Ilya ordered new rims, he wanted to make them bright, and he chose light green ones. At the same time, body defects such as a dent on the roof and traces of neighbors' parking were corrected for this purpose, the side mirrors were repainted to match the color of the wheels and light green stripes were made on the body. This, of course, immediately refreshed the car.

What is possible and what is needed

Yes, this Daewoo Nexia has little power - at best, about 120 hp. With. at 6,700 rpm, but this is compensated by other modifications. In principle, bringing the “herd” of forces to 190-200 is not difficult and not very expensive, but in the future this will require rebuilding the entire car in a circle in order to maintain balance. After all, you cannot strengthen one node without paying attention to other components.

In general, Ilya admits that it is not easy to make improvements to Nexia. The car is positioned as an excellent option for pensioners, summer residents and taxi drivers - accordingly, among the assortment of tuning stores, it is almost impossible to find anything interesting for it. There are simply no ready-made goods and there never will be. Any question that arises forces you to think creatively and dodge in every possible way - this is not JDM, where there are kilotons of tuning things and ready-made kits for almost any car. Some similarity between the model and the Opel Kadett helps a little, but not much: some parts may come from Opel, although this is rare. In this case, the installed springs and steering wheel were sold as parts for Opel.

What's next? As you know, tuning can only be paused, but not completed. The plans include searching for increased traction, thinking about the rear brakes, and there is also a desire to change the already tired acoustics. Well, given the unusual nature of Ilya’s choice of car for tuning, any surprises are possible!

Machine design update

These features of the car and its tuning in particular will be visible in the photo. Nowadays, many car enthusiasts are filming masterpieces made with their own hands on a mobile phone camera and posting them on social networks. Updating the design of the Uz-Daewoo Nexia n150 does not always look good in the photo (not because the car is bad, but because of the wrong approach to updating the design of the car), but some people really are geniuses at repainting a car.

An example of unsuccessful tuning of Nexia n150 (the headlights will not fully illuminate the road)

How to properly carry out this part of car tuning so that you have something to show off in the photo? To do this, follow these tips:

1. Don't go overboard with the amount of detail. Of course, you want to install a large number of LED patterns on the car, update the headlights, repaint it in colorful colors or install interesting stickers on the vehicle. But you should choose a few things from this list as suitable for this design solution. There is no need for the car to be colorful.
2. Listen to your intuition. Of course, it won’t give you a 100% guarantee that you will tune the Uz-Daewoo Nexia well, but updating the car’s design is a creative process. And this means that he is only intuitive.

These are the basic points characteristic of tuning the design of Uz-Daewoo Nexia. Now let's get down to certain elements of its design.

1. Disks. Updating the wheels on a car allows you to visually increase its value, which is important for Daewoo Nexia owners, since everyone knows that this car is inexpensive. Selecting the right disks is not an easy task, and the danger of being left with hardware instead of full-fledged disks also remains. Which disks should I choose? It all depends on your taste, but you need to take into account not only their beauty in itself, but also compatibility with the sharp details of the famous car from the Korean class=»aligncenter» width=»842″ height=»474″[/img] Alloy wheels on Nexia n150

2. Salon. This component of tuning may be invisible from the street, but for people getting into the car it can mean a lot. In principle, for passengers, the interior enhances the car more than external tuning. You probably shouldn't even spend money on changing the exterior. Interior tuning is a multi-faceted issue and includes many factors, such as seat upholstery, changing car inserts, and varnishing certain interior parts. In general, there is room to expand.

"Low-budget" option

The situation, of course, changes the availability of funds for such pleasure; here you can already approach the issue of tuning quite qualitatively. First, as a rule, sports body kits for the bumper or a completely finished sports design are purchased. The practicality of such sports versions is simply amazing, because cars at speeds above 150 km/h receive noticeable stability, and it’s all about the aerodynamic properties of such bumpers. The appearance also takes on quite noticeable aggression. After the bumper is replaced, installation of additional aerodynamic thresholds and spoilers usually begins.

Naturally, it is recommended to buy all these parts from one manufacturer so that they look in the same style, but these recommendations are not always used, because each person’s desires are unique.
