E-GAS or electronic gas pedal is installed on all Lada models (XRAY, Vesta, Largus, Granta, Kalina, Priora and Niva 4x4). Owner reviews about it are not reassuring; many complain that the e-gas pedal is “dumb” (less sensitive and informative than a conventional cable). Did you know that in some cases the electronic accelerator pedal can be adjusted to be more responsive and a little livelier?
We determine the model of the accelerator pedal; this can be done by the catalog number, which is glued to the side of the body. If you cannot access the sticker, you will have to remove the electronic gas pedal:
- Disconnect the block with wires next to the gas pedal;
- Unscrew three nuts using a 10mm wrench;
- Remove the housing and pedal assembly.
The manufacturer installs at least two types of electronic gas pedals on Lada cars (depending on the year of manufacture):
- Old model (catalog number: 11183-1108500);
- New sample (article: 11183-1108500-01).
Each block is modified differently. Attention! You do all further actions at your own peril and risk. In addition, you may lose your warranty.
Need for maintenance
The prophylaxis procedure should not be carried out in the absence of obvious reasons.
Before starting, you need to carefully evaluate the condition of the throttle valve. If there are no obvious signs of tar deposits and areas of coking, then the reason for unstable operation may lie elsewhere. Also consider the mileage of the car. Experts recommend resorting to flushing no earlier than after 100 thousand km. But on some cars, for example, a Ford Focus, it may be necessary to flush it after 30 thousand kilometers.
You should know how to clean your throttle body to achieve the desired result. This requires a special carburetor cleaning solution, for example, Abro Carb & Choke Cleaner or similar products. The assembly must be dismantled; only in this case can the maximum effect be achieved, otherwise carbon deposits will remain inside the tubes. Disconnect all pipes from the throttle valve to gain good access to the inlet part of the assembly.
Remove carbon deposits delicately using a clean rag or soft brush. Do not use excessive force; you may damage the valve. The internal elements are coated with a thin layer of molybdenum, which novice car enthusiasts mistake for harmful deposits.
The consequences of zealous cleaning can be different: the moving part of the damper will begin to bite, or vice versa, in the closed position it will begin to let air through. In this case, it will not be possible to do without repairing the throttle valve.

Throttle learning idle
After flushing the unit or reflashing the ECU, the throttle valve should be trained to idle. To do this, fulfill the following conditions:
- check the voltage on the battery with the engine off, it should be at least 12.9 V;
- the coolant temperature should be in the range from 70 to 100 degrees;
- the steering wheel must be in a neutral position;
- The gearbox oil must be warmed up;
- all electrical consumers are turned off;
- automatic transmission handle in position P.
New Lada: How much brake fluid is needed for a complete or partial replacement |
AVTOSTUK.RU Failure to comply with the above requirements will lead to incorrect operation of the engine, so they are mandatory. After warming up the engine, you must:
- turn off the ignition for 10 seconds;
- make sure that the accelerator pedal is in the up position;
- turn the key to the ON position for 3 seconds (do not start the engine);
- Press the gas pedal all the way 5 times within 5 seconds and release it for the last time;
- after 7 seconds, press the gas pedal all the way and wait until the “CHESK ENGINE” display lights up continuously;
- After pausing for 3 seconds, release the gas pedal.
Try to start the car, the attempt can be repeated several times. During stable operation, rev the throttle several times and the idle speed should return to the acceptable range.
The procedure for learning the throttle using a PC and car programs has its own specifics, depending on the brand of car, etc. Therefore, it makes no sense to describe the entire process in detail. But first you need to install special software on your PC, for example, VAG-COM for a VAG car group (or other) and drivers. The following is the standard connection order for all:
- turning on the ignition;
- connecting the PC to the car diagnostic connector with an information wire;
- launching software on a PC;
- conducting a test;
- receiving information about readiness for further work - the inscription: “The adapter is ready for work.”
Following a special algorithm, you will be able to coordinate the remote control and the ECU in the “throttle fully open/fully closed” modes for cars with both an electronic and mechanical gas pedal. In this case, the throttle valve training is carried out when the car is warm and the above requirements are met.
Chip tuning e gas
Hi all! Today is a great spring day, good weather and pre-holiday mood! The opening of the Paralympics is also an excellent and kind world event in the light of recent days!
I also had a small experience with my car, quite ordinary for many car enthusiasts, but for me this is my first experience with this car. Therefore, I decided to share the news with you, my colleagues in the industry and interests.
I won’t beat around the bush anymore and irritate you with unnecessary letters (God knows, I tried! :]), in short, I finally flashed my Priora!
Someone will think: “Well, what’s wrong with that, I’ve done this a hundred times!”
You can’t argue with this, every third, if not second, car enthusiast consciously (and sometimes not, as they say, as a tribute to fashion) goes to the service of skilled craftsmen for “magic” chip tuning. Why "magical"? Yes, because many believe that chip tuning will turn its swallow into a sports car and add at least a dozen horses.
But you shouldn’t expect good results on a stock engine with factory hardware; however, correct firmware will help to cope with many of the shortcomings and illnesses of the factory program.
Before this, I had already chipped my previous Priora, twice and on two different ECUs. But I was not happy with the result, because... In addition to a slight improvement in dynamic characteristics, both times I experienced detonation on a warm engine. Naturally, it was possible to correct the ignition timing angles, but I refused this, considering that “playing with angles” was the basis of these miracle firmwares, called chip tuning from Paulus. Therefore, to update the firmware of the current car, I decided to approach this issue in more detail and first found out where we have car chip workshops in Tula. Among the huge number of such companies, I singled out a few, called, searched and read reviews. I immediately dismissed those that offered Paulus firmware, because... There are no official representatives in Tula, and I didn’t want to stage who knows what for the third time.
The second problem for choosing a service was the ECU of my Priora. I was “lucky” because... I came across the M75 block, produced by Itelma and which is the latest development of AvtoVAZ. In this regard, not everyone undertakes to flash these brains, and the search circle has narrowed even further.
One of my friends advised me to go and get E-gas upgraded in Shchekino, a neighboring town in the Tula region. There is no problem getting there, it’s very close, but at first I wondered how it was that I couldn’t find a good craftsman in the regional center, but then a craftsman showed up in the region!
I started “making inquiries” again and came across links to this master on several forums, and on the website chiptuner.ru he was designated as a regional representative for chip tuning and car diagnostics (chiptuner.ru/content/asrv_46/). This site is quite large, one of the first such portals and has in its archives the most complete information on the diagnosis and repair of electronic car systems, including chip tuning. This, of course, flattered me, and I decided to call this master. The conversation turned out to be interesting, and this only confirmed my decision to go and see him.
This is how I met Valera. A few more days of “elections” and I headed to him. I asked to leave work for a couple of hours and went to Shchekino.
I arrived, service as service, nothing remarkable, there are thousands of them.
They removed my block, Valera went home with him and the laptop. The wait was long. This was alarming. He came out and said that he couldn’t connect to the unit. I think that’s it, I came to the master, it’s called! But Valera quickly recovered and called his friend from Tolyatti, and he emailed him the program for connecting to my unit and the firmware. It turned out that he was sewing my block for the first time, and before that he had to deal only with an analogue of my brains - Bosch ME 17.9.7.
Signs of throttle adaptation
The throttle valve in its modern form is one of the last components to undergo electronic modernization. Instead of mechanical rods, a compact electric motor is installed on it, which serves as an actuator.
The signal to it comes directly from the throttle sensor. Together, this system allows you to control the engine correctly, supplying the required volume of fuel mixture to the combustion chambers in a timely manner. There are several signs by which you should start adjusting the throttle position.
For example, when you suddenly release the gas pedal, the engine does not go to idle and stalls; the following can also happen:
- Unstable engine operation at idle;
- a significant “freezing” of revolutions around the 1.5 thousand mark;
- drops in speed when gaining power;
- the “CHECK ENGINE” indicator lights up on the dashboard;
- difficult start at ;
- lack of response when pressing the gas pedal.
New Lada: We remember the most unusual versions of the Lada Priora, which is being discontinued - Selector - Motor
Depending on the engine type, there may be a slight loss of power, for example with engines with a V8 configuration. Also, fuel consumption almost always increases. These signs appear especially often on cars with a mileage of 30 thousand km or more, equipped with turbocharging.
What happened
I tried all the described procedures and checked the result. I accelerated to 100 km per hour and timed it. The result was an acceleration time of 10.4 seconds, although it was almost the same before. What does this adaptation provide? The dips when the pedal is pressed hard have disappeared. The slight twitching of the car when driving slowly in 1st gear has also gone away. Therefore, adaptation of the gas pedal still needs to be done once every 5000 km.
Not too big changes were noticed. If anyone decides to make such an upgrade, I do not recommend moving the slider too much. It is enough to move it forward by 10%. This concludes the review, thanks to everyone who subscribes to the channel and supports! Write how you modified or repaired the electronic pedal, and what came of it.

Causes
The most common reason for an adaptation to be made is the consequences of throttle valve maintenance. As a result of operation, a large amount of deposits forms in this unit, therefore, after flushing, the position of the throttle valve changes, and the ECU continues to send signals about its condition until maintenance.
Over time, natural wear occurs on the resistive layer of the sensor potentiometer and the moving elements of the throttle valve; in this case, after adaptation, it will most often require replacement. It is necessary to conduct training if changes are made to the ECU settings (chip tuning), especially if operations have been performed to increase engine power.
The procedure is performed using special programs on computer equipment or without them (a strictly defined procedure, which will be discussed below) depending on the brand of car. Auto electricians must take into account the features of the model, year of manufacture, and type of ECU installed on the vehicle.
When and how to do it yourself
When to perform throttle valve zero adaptation and misfire diagnostic function adaptation:
- After replacing the ECU controller or resetting the controller using a scan tool.
- After replacing the throttle assembly.
Throttle valve zero adaptation procedure:
- When the car is stationary, you must turn on the ignition, wait 30 seconds, turn off the ignition, wait until the main relay turns off.
Adaptation will be interrupted if:
- the engine turns over;
- the car is moving;
- the accelerator pedal is pressed;
- engine temperature is below 5 °C or above 100 °C;
- Ambient temperature is below 5 °C.
Procedure for adapting the misfire diagnostic function:
- warm up the engine to operating temperature (parameter value “Coolant temperature” = 60...90 °C);
- accelerate the car in 2nd gear until higher crankshaft speeds are reached (parameter value “Engine crankshaft speed” = 4000 min-1) and perform engine braking (“Engine crankshaft speed” = 1000 min-1);
- Perform engine braking six times in one trip.
Adjustment
The adjustment process may vary on different car models, since different manufacturers use mechanisms of different designs. But the same principle can be applied for configuration. As for a specific model, it is better to find information on it in advance.
To begin the adjustment, the first step is to remove the pedal from the holding bracket. Next, loosen the screws securing the cover. One screw holds the cover in a certain position - it must be completely unscrewed. The cover is turned to the side clockwise until the end, then the screws are tightened again.

This adjustment will reduce pedal response time. Some car owners note that after such adjustments, the response speed can even be compared with a mechanical pedal. Adjustment allows you to improve engine performance and improve the start of movement from a standstill.
In cases where a pedal with low sensitivity is needed, it is necessary to rotate the cover in the opposite direction - counterclockwise. The machine begins to respond to presses not so quickly.
Sometimes you can come across harmful adjustment tips - drivers advise placing shims under the lever. This is the wrong approach. Sometimes the pads get caught under the contact pads in the potentiometer, and the machine may lose control as a result.
Replacing the gas pedal on Grant
The replacement procedure is quite simple and does not require special technical means. In order to dismantle the unit you will need: - A key for 10.
Sequential steps to replace the gas pedal of a Lada Granta:
1. The first step is to remove the negative terminal from the battery. 2. Next, you need to move to the driver’s side of the car. 3. Above the gas pedal, find and disconnect the contact chip that is connected to the sensor connector.
4. After that, take a 10mm wrench and unscrew the three fastening nuts. When there is insufficient internal space, it is most convenient to use a socket wrench.
5. Remove the pedal from the special mounting pins. Reinstallation is carried out in a mirror sequence.
