The electronic control unit (ECU) is designed to control the operation of all systems of the internal combustion engine. The software included in it by the manufacturer determines the moment of the spark discharge in the working cylinder, the amount of fuel supplied to the injector nozzles, regulates the crankshaft speed in idle mode of the engine, and also changes the ignition timing. All parameters are calculated based on signals received from various sensors.
It is necessary
- - a computer,
- - adapter.
Instructions
Step 1
To make changes to the parameters of the motor, you need to change the software algorithm. As a rule, this is done in the course of a sports car tuning.
Step 2
Flashing is done in several ways, including: replacing the ROM chip in the ECU, installing new software using a personal computer or laptop, which are equipped with the necessary adapter for connecting to the vehicle's diagnostic connector, installing an additional electronic unit at the ECU input that changes the parameters of signals transmitted ECU sensors of engine systems, etc.
Step 3
There is no need to remind car owners that the implementation of the firmware of the electronic control unit can only be trusted by highly qualified specialists. Making changes on your own to the operating parameters of the systems is fraught with very serious consequences, up to the failure of the vehicle's power plant.
