Lada Priora is a worthy representative of the Russian automobile industry. It is on a par with foreign-made “classmates”, but compares favorably with them due to its attractive price. The operation of the Priora engine is controlled by an on-board computer, or ECU. He manages the fuel supply system and ensures the synchronous operation of all units.
Every car has hidden capabilities. Chip tuning allows you to take advantage of this potential. Reprogramming is carried out through the OBD diagnostic port. By adjusting the engine control program, you can change the air-fuel mixture supply mode, ignition timing and other engine operating characteristics.

A little about firmware
If you still decide to upgrade the ECU yourself, use only high-quality firmware. According to reviews from car enthusiasts, Paulus firmware is a good option, as they “correctly” change the settings of the electronic unit. Moreover, they should be downloaded from official sites, and not from third parties. Because you can run into a fake and spoil the characteristics of the car.
Therefore, be extremely careful when choosing new software, since the cost of an error is very high and there is a risk of damaging your car with low-quality software.
How to do chip tuning yourself
As already mentioned, the best option for tuning is to contact a car service center. There, specialists will be able to accurately change important settings of your ECU without damaging the operation of other vehicle systems.
Flashing the VAZ 2114 ECU
If you really want, you can try to flash the firmware yourself - to do this you will need to connect the PC to the ECU via a programmer and set the required settings in the working window of the screen (on different machines, electronic units can be programmed using different programs, each of which has its own operating features; according to For this reason, it won’t be possible to give any specific advice here on how to flash a VAZ 2114 step by step).
The only thing you should remember when performing independent chip tuning is the relationship between all operating parameters of the engine. So, by increasing its power to the maximum possible value, we will get a significant increase in fuel consumption, and along with it - increased toxicity.
It should be said once again that if you are completely ignorant of programming and have only basic PC knowledge, then doing chip tuning yourself is absolutely not worth it. After all, the result obtained can be not only zero, but also negative.
How to flash Bosch ECU 7.9.7+
Here I will tell you how you can flash the ECU of a VAZ 21703 Lada Priora, because I myself decided not to pay anyone the money and create it myself, everything worked out and works great, and those who say and scare that you won’t succeed They just want to take money out of you!
I won’t lie, you will still have to spend around 1000 rubles. to purchase an adapter and firmware, but it’s worth it, after which you can upload any firmware for yourself to your taste and create it for your friends for not a huge fee and money to return and drink beer.
For this we will need:
All-purpose adapter KL-Line BM9213 USB MASTER KIT for tuning a car with an injection engine, you won’t chip the carburetor with it,
You can read more about it and how to purchase it here. For the adapter, the virtual COM port driver for Win XP, Vista can be downloaded here, you can also use another adapter VAG COM USB KKL v409.1 which can be purchased from our partners, this one The KK-Line adapter only comes in a housing and costs funny money.
Next, for flashing the “chip” firmware, we will need ChipLoader 1.96; you can also use the latest version of ChipLoader 1.97.7, and the previous one works smoothly, so I don’t see the need to use the new one.
in the Help > Help tab you will find User Management, also go to options and uncheck all the boxes as shown in the figure above. In order for the block to start being sewn, it needs to be modified according to the annotation in the User Administration, everything is carefully described there.
The firmware will also be useful for you, if you just want to try chipping, then first you can try the free Tuned VAZ firmware, but I would recommend immediately flashing the normal VAZ commercial firmware, the difference is significant.
Also, almost all beginners ask the question, why does ChipLoader give an error after selecting a 260 kB firmware?
The answer is simple, ChipLoader supports firmware only in full-size format, i.e. “Decrypt” with a size of 832 KB (851,968 b) to decrypt the firmware we will need the SMS Enigma new v 1.10 program
First, you need to remove the ECU to read the inscription on the sticker, later you need to find its type, you can create it here, my sticker looked like this:
I created my own block, it’s Bosch 7.9.7+, in order to program it, it needs to be modified, it’s written how to create it here
Next we need to assemble a non-tricky circuit, I simply made it from thick wires so that they could fit onto the ECU pins.
I took 12 volt power from 8 1.5V batteries, you can use a power supply, but only a stabilized one, do not use pulsed ones from the computer from the one from which you will be sewing, units from Sega Dandy consoles and other Chinese equipment are not suitable, it is better to take power from battery straight from the machine, and sew on a laptop without connecting to the network, or use an uninterruptible power supply, in which case suddenly the light turns off
