Chip tuning of VAZ (engine) 2114: we flash the brains with our own hands or at a service center

Recently, an increasing number of car enthusiasts are interested in such a subject as upgrading their car - and this is not surprising, because everyone wants to customize the car “for themselves”, to make it unique. One of the options for such changes is chip tuning for the VAZ 2114. It allows you not only to give individual features to the car, but also to make its driving characteristics much better than the factory ones. We’ll talk about what it is in today’s article.

Firmware for VAZ 2114

Firmware for VAZ cars with ECU Bosch M7.9.7 and Bosch M7.9.7+

Purpose:

The firmware set is intended for chip tuning of VAZ cars with ECU Bosch M7.9.7, Bosch M7.9.7+.

Description:

The firmware has significantly improved dynamics and elasticity. Smooth running and torque reserve at low speeds are ensured. Reduced fuel consumption. The fuel supply cutoff is shifted to a safe value.

There are modifications for any toxicity standards - Euro3, Euro2, Euro0.

Modification of standard BC AMK 2113 2114 2115

, datasheets collected, pinouts compiled

The AMK should use the MC33290 chip, but since this chip is impossible to get, you can use any of those that are at hand. In my case, this is L9637D, it is available for free sale, as well as in IMMO APS-6 and many fresh ECUs,

Then, after rummaging around (I can’t give a link to the source, because I don’t remember), we found the latest firmware for the microcontroller (PIC19F252) of AMK itself, namely PR57 (it was PR31). It’s easy to check the software version; you just need to hold down “+” and “-” with the ignition off and, without releasing the keys, turn on the ignition. There was no need to think about how and with what to flash this chip; long before this, a programmer for similar microcontrollers had been assembled (GTP-Lite theme from Radiocat), and an adapter from the SSOP28 - DIP28 case was also at hand. The microcircuit was soldered with a hair dryer and rolled into the adapter, stitched and then returned to its rightful place in the same way.

after all the manipulations we get the following - the T button remained the travel time, but + T air overboard was added (we didn’t even have to throw in an additional wire. It was already crimped into the block from the factory)

-it became possible to enter a correction coefficient for instantaneous fuel consumption (L/H) in %

— the voltmeter has now moved to the KM/H button next to the average and instantaneous speed

Firmware for VAZ cars with M73 ECU

Purpose:

The firmware set is intended for chip tuning of VAZ cars with M73 ECU, installed on the entire line of VAZ cars from model years 2008 to 2010 and meeting Euro-3 environmental standards. Firmware with all software identifiers is available, including those with modified hardware implementation.

Lada Priora (engine 21126)

Description:

In all modified firmware, the fuel assembly (fuel-air mixture) and ignition timing (ignition timing) are optimized in almost all engine operating modes. The Lada Priora firmware corrected factory errors in cold start calibrations, which made it impossible to do so at temperatures below -20 degrees Celsius. The system input to the IAC (forced idle) has been optimized and a factory error in calibrations has been eliminated, leading to the engine stopping when entering the idle mode after partial load mode. The injection phase and fuel cut-off speed have been changed. Fuel consumption is significantly reduced, with a significant increase in dynamics.

What is needed for electronic tuning

The main “tools and devices” that will be needed when performing firmware for the VAZ 2114 8 valves are:

Programmer.
Disk with the required firmware version.
PC or laptop.

ChipTuningPRO at work

If there are no problems with the last two points, then the programmer will need to be purchased. This can be done either in a car store (if not in stock, then order it) or via the Internet. It is worth considering that this device is far from cheap, and buying it for a single use is not at all profitable.

The best option would be to purchase it together with other car enthusiasts or contact a specialized workshop, where all reprogramming can be performed by professionals.

VAZ "Classic" (21067-1411020-47)

Description:

In the modified firmware, dynamics and elasticity are improved due to changes in the fuel assembly (fuel-air mixture) and ignition timing (ignition timing). Torque distribution has been optimized by changing the electronic throttle operating algorithm. The “softness” of engine operation in idle and low fill modes has been improved. The system operation algorithm in air conditioning mode has been improved. Changed the speed and fuel cut-off speed.

The firmware is presented in versions for Euro-2 and Euro-3 toxicity standards, as well as for Euro-0 conventional standards. In firmware for Euro-2 toxicity standards, the second oxygen sensors and control of the catalytic converter are completely disabled, which allows their complete removal from the system. Firmware for cars meeting Euro-2 emission standards comes in two versions: IMMO and IMMO OFF. The kit also includes firmware for working with gas equipment (gas equipment) of the 3rd and 4th generations.

Instructions for updating software on BC State

In this manual I want to show you the process of updating the software for BC State of any models!
My BC State 115 x42 RGB will be used as an example. What BC found out not long ago, and decided to reflash for itself. For this procedure, we need a USB adapter for BC State, which is sold at the office. website in Russia, and in Ukraine there are representatives and you can ask them about the availability of this device. But the package of this adapter does not provide a cable directly to the BC itself; it needs to be made. This is due to the fact that the adapter is universal and cannot provide all connectors. Well, making such a cable will not be difficult, everything is very simple, you just need straight hands, a soldering iron, terminals (can be bought at any radio market), a mother connector from the power supply to the PC (can be cut off from a non-working computer power supply) And so let's get started! To connect the wires to the adapter, I used a mother connector (flup power supply) from a broken computer power supply. I just cut it off along with the wires, but they were short and I decided to lengthen them, with wires from the same power supply. I also decided to swap the wires, for greater clarity: Red - 12v OUT Yellow - K-line (data) Black - Ground

And I also removed the unnecessary 4th wire, we will use only 3 wires.

We do everything carefully and solder everything, including the joints of the two wires, plus I cover the soldering joints with special insulation! So as not to short the thread. It looks good and will last longer)

Firmware for VAZ cars with M75 ECU

Purpose:

The firmware set is intended for chip tuning of Lada Priora 1.6L 16V cars with M75 ECU installed.

Lada Priora (21126-1411020-42)
Lada Priora (21126-1411020-47)

Description:

The firmware is presented in versions for all toxicity standards. Firmware for cars meeting Euro-2 emission standards comes in two versions: IMMO and IMMO OFF.

How to use?

We will briefly tell you how to use these programs and how the hacking procedure goes.

The program must be downloaded, activated and installed on the laptop;
Rent a programmer (or buy, but the device is not cheap);

Prepare the cords to connect to the car;
Connect the programmer to the laptop;
Next, connect it to the car (OBD 2 diagnostic connector);

Turn on the ignition;
Run the program to diagnose the car for errors;
If the latter come out, remove them;
Next, run the firmware file;
At the end of the process, turn off the ignition and wait 5 minutes;
Start the car and repeat the diagnostics until it shows no errors;
Ready.

This is roughly how the procedure for flashing a car via a laptop is carried out using special utilities. Is it even worth doing this? Think about it, it’s not for nothing that the manufacturer sets the average parameters in the ECU. This is the ideal ratio of the power it produces and the consumption of its resources. It turns out that by hacking the factory settings and installing your own, you are breaking this balance, the consequences of which will only appear in the foreseeable future. In short, we advise you to carefully evaluate all the pros and cons. And yes, before starting the procedure, carefully study the stages of the process, choose which program can change the firmware (do chip tuning yourself) of your car, download the software from trusted sites and take care of high-quality equipment. Good luck to you and have a great ride in a powerful car!
