Is it worth changing the firmware (chip tuning) for Lada Largus cars?

Professional chip tuning capabilities

A car's engine control unit is an electronic device responsible for engine operation, generating the necessary commands for fuel supply, ignition, etc. based on data received from sensors on the number of revolutions, air flow, and shaft position.

Factory firmware is created by the manufacturer with the condition that the engine will last for a certain time even when using fuel and lubricants of insufficiently good quality. This aspect protects the car from breakdowns, however, it reduces power and increases fuel consumption.

After reprogramming your machine will have:

  • excellent acceleration dynamics;
  • increased maximum speed;
  • excellent elasticity, which will ensure a minimum number of downshifts;
  • reduced fuel consumption.

SVVMotorSpor specialists are ready to perform chip tuning of the VAZ 2114 with a guarantee of increasing power by up to 10%. This procedure involves replacing the factory chip with a new one with a guarantee of increased engine power.

To flash the firmware, the chip is removed from the controller and flashed individually or using a special connector; there is no need to remove it for this.

First, the company’s specialists must make sure that the engine system is in good working order, otherwise chip tuning of the VAZ 2107 will not bring any benefit.

You should not carry out chip tuning on your own VAZ; at best, the behavior of your car will not change at all. And in the worst case scenario, all factory settings will be lost, which will lead to complete malfunction of the machine. Restoring these settings will cost you a significant amount.

DIY chip tuning

The cost of updating the Lada Largus ECU software when contacting a specialized organization will be several thousand rubles. But car enthusiasts want to save money, so they are thinking about carrying out this procedure themselves. You can study the entire tuning process in detail, contact the experts, trust the chip box, or purchase all the necessary equipment and ready-made software from a specialized store.

Chip box

Installing a chip box is the simplest option that does not require time or large financial investments. The method is also suitable for beginners. It will be enough to figure out what type of engine is under the hood and buy the appropriate box. The device is inserted into the diagnostic connector, then all adjustments are made automatically. The procedure is fast, simple and straightforward. When the device is disconnected, the ECU returns to standard settings without any consequences.

Manual firmware

Compared to a chip box, which negatively affects the life of the internal combustion engine and other systems, flashing the chip is more effective. This is due to the fact that the process involves calibrating the operation of the controller, and does not replace signals to actuators. The controller firmware helps increase the power of the power unit and stabilizes idle speed when the air conditioner is running.

The maximum speed limit will be removed, the on-board network and devices will work more efficiently, since the standard firmware initially reduces all characteristics to increase the resource. Reflashing will not reduce the engine's capabilities, since all electronics will be used to the maximum. But installing new software yourself is more difficult. For this procedure, you need to know all the nuances and subtleties of the chip tuner, find and buy equipment and software.

The firmware process is the same for any type of engine, no matter whether it has 8 or 16 valves, the algorithm will be the same - the only difference is in the software that regulates the operation of the engine.

Execution of work

To reflash the engine control unit, you will need the following components:

  1. Firmware program. Official software is preferable. If an unofficial one is used, it must be of high quality and verified.
  2. A laptop with a set of programs that need to be downloaded first.
  3. Programmer. This device will flash the ECU. Due to its high cost, it is better to try to rent the device.
  4. A set of adapters for connecting to the diagnostic connector.

Before chip tuning on Largus, you need to make sure the engine is working properly. Otherwise, the consequences may be unpredictable, including engine failure. The workplace should be prepared in such a way that there is access to the electrical network nearby.

If during the flashing process the laptop battery is discharged before the device is turned off, the consequences will be unpleasant - in the best case, the engine will not start at all. To prevent this from happening, connect your computer to the power supply in advance. The laptop should already have the necessary software, drivers and a connected programmer installed.

After carrying out the preparatory procedures, the programmer is connected via an adapter to the diagnostic connector with the ignition off. Then the laptop turns on, followed by the ignition. Next, the algorithm of actions is as follows:

  • run the firmware program and find any ECU errors - they need to be deleted from memory;
  • run the file with the firmware, after which you just have to wait for the process to finish;
  • after completing the procedure, turn off the ignition and turn it on again after a few minutes - if the firmware program shows the same errors, the procedure will have to be repeated again;
  • if there are no errors, you can start the engine and evaluate changes in its operation, and if necessary, make a test drive;
  • If everything works fine, the firmware procedure can be considered complete.

Chiping a car with your own hands is both an opportunity to save money and a big risk. The savings in this case are conditional, since the equipment for such tuning is expensive. And it will take a lot of time to study the theoretical part. Unknowingly, you can choose the wrong firmware, especially when downloading various assemblies from third-party developers from the Internet. To correct the situation, you will have to contact specialists and pay more than the cost of the firmware.

How do engine characteristics change after chip tuning?

Car manufacturers must take into account the requirements of various countries in order to be able to sell their products there. In other words, there is one car, but the operating conditions are different. Despite the enormous resources and capabilities of car manufacturers, they cannot provide optimal ECU settings for a particular region. And, as a result, the control program sets values ​​for fuel supply and ignition control that are too gentle, too low, or one might say too reasonable. And this, in turn, leads to a decrease in such characteristics as power, torque, and fuel consumption increases. Those. after Chip tuning, the hidden potential of the engine is released, some of which is not realized by the too “tight” program.

Power units of the LADA Largus car

The LADA Largus and LADA Largus Cross cars are developed on the basis of the popular Renault (Dacia) Logan MCV station wagon and differ from the prototype in the suspension adapted for domestic roads. They are equipped with gasoline 4-cylinder French power units with a cylinder capacity of 1.6 liters:

  • 8-valve K7M with a power of 86 hp. With.;
  • 16-valve K4M, the power of which can range from 102 to 115 hp. With.

In addition, the LADA Largus is equipped with a 1.6-liter VAZ-11189 engine with a power of 87 hp. pp., which is a VAZ-11186 engine adapted to EURO-5 requirements.

Long-term operation of the LADA Largus and LADA Kross station wagons has shown that all the engines they are equipped with are somewhat weak. At the same time, the use of traditional methods of functional (mechanical) tuning, which boil down to making changes to the design of power units, does not produce significant results. The easiest way to eliminate this drawback without changing their design is to use modern chip tuning technologies.

What will you get out of it, do it or not?

A serviceable car, after reprogramming and under all equal operating conditions, will have:

  • Better acceleration dynamics.
  • It will become more “high-torque” with less pressure on the accelerator pedal - engine torque will increase and shift to lower speeds, and the maximum speed will increase.
  • Elasticity will improve, i.e. When driving, you will have to switch to lower gears less.
  • The engine will run more smoothly.
  • Fuel consumption will decrease (with a normal, calm driving style).

How much will be added?

By the way, what moves the car forward is not power, but TORQUE - the product of force and the arm of the lever to which it is applied. To be brief, it is the amount of torque that is important for accelerating a car, and the better it will accelerate, the greater the torque for the required engine speed. Power is a derivative of torque, and the higher it is in the end, the faster the car will be. In other words, for a car to accelerate quickly and be flexible, torque is needed, and for it to drive quickly, power is needed. So, I repeat, after programming, the torque increases and shifts to the region of lower speeds and at the same time, as a derivative of the torque, the power increases accordingly. In the end - in good working order! The car will have lower fuel consumption with increased torque and power. It will be more pleasant to operate the car, at lower costs. I think everyone strives for this.

And so, after pre-programming we get:

  • on naturally aspirated engines, torque and power increase by 8-10%.
  • on turbocharged engines, the increase in torque can reach 40% and power by 35%.

If your car with a naturally aspirated engine has a passport rating of 100 hp. and 140 Nm of torque, then after programming the car will have 110 hp. and 154Nm respectively. If the engine is turbocharged and has the same 150 hp. and 210 Nm, after reprogramming it will be about 190 hp. and 270 Nm.

How to do chip tuning correctly?

A prerequisite before reprogramming is to be sure that the car, its engine and its control system are in good condition. Those. Before carrying out chip tuning, diagnostics are required. In this case, everything that affects the operation of the engine should be checked. If after diagnostics there are no comments, only then reprogramming work is carried out. Chip tuning is not a means of repairing a car, but a means of improving its performance and driving characteristics.

Where and how can you perform chip tuning?

Theoretically, chip tuning of Largus can be done in any place convenient for the customer. First you need to connect the programmer to the diagnostic connector. If the equipment is licensed, then it is capable of flashing a large number of different cars through the diagnostic block.


Chip tuning is a popular type of car engine modification

After connection, the control unit is backed up, the data is saved, and chip tuning is performed (replacing the ECU software). After these actions, the owner receives a completely different car, which is capable of accelerating more quickly and has different power.

Lyrical digression

So you decided to do Chip tuning, you come to the service center and declare your desire... The master comes out, inserts the laptop plug into the connector, presses the buttons and after a few minutes announces - “... The car is ready, from you N-000 rubles, I’ve done everything... " Or another option - several owners of the same brand gather at the same time (to make it cheaper), call the specialist, he arrives at a certain meeting place with a laptop, 20 minutes in advance. “changes” 4-5 cars and, satisfied, how could it be otherwise, having received the money, he leaves. Now the question is - what will be fair to you, as the owner who spent the money? An example from life - a young man comes to 2115 with a desire to do Chip tuning, I outline the methodology, he says - “... I only need a Chip, I already did the diagnostics there yesterday, everything is fine with me...”. I answer, “... I must be sure that the car is in good condition, since I give a guarantee for my work...”, I check - I find a faulty air flow meter, spark plugs - I say that I need to go to the store, buy it and replace it, I won’t flash it without replacing it. His friends declare: “... You’re making money here, we’ll go somewhere, there’s a Master there, he’ll do everything cheaper and won’t change anything.” Agree that the actions of the guys are devoid of elementary logic, then what is the difference between the owners who gathered in a group and did Chip tuning in 5 minutes for touring artists from St. Petersburg, Moscow, etc.? Do they feel deceived?

Chip tuning in a car service

The chip tuning process in specialized organizations looks approximately the same. The car owner comes to the service center, where, using special equipment, the factory firmware is read from the control unit. It is then modified depending on the client’s wishes - to reduce fuel consumption, increase power, remove the speed limit. After this, the ECU is flashed with a modified program.

Often, such services already have a set of programs for different cars - in this case, the duration of the procedure is reduced. After installing the new software, the warranty period begins, during which you need to run the car in. During this time, the client may demand to correct one or another parameter that made the operation worse, or to return the money for “chipping” if the result is not satisfactory. In this case, the service is obliged to “roll back” the firmware to its factory state.

Program tuning is one of the most difficult chip tuning procedures. The complexity depends on the wishes of the driver and the system that controls the engine. Tuning consists of making changes to the existing calibrations, after which checksums are calculated. If there are already similar calibrations in the database, they will be exported to the program. These procedures are carried out without the participation of the car owner. On average, chip tuning of a Lada Largus will cost about 4-5 thousand rubles.
