Engine controllers without secrets
We know intuitively that car engine controllers play an important role in the correct operation of all vehicle mechanisms, but we are not always fully aware of what their operation is all about. So we explain what are and what are the engine controls, how affects them currently very popular chip tuning and what conditions must be met to be able to undertake repairs and modifications on this device.
The role of the engine controller in the operation of the vehicle
The electronic module that controls the work of the combustion engine, based on data stored in the computer memory (e.g. maps, tables) plays a very important role, consisting in:
gathering,
…comparing,
coordinating the information coming from different vehicle sensors,
selection of ejaculation time and volume and appropriate ignition time.
Therefore, it is a common point, connecting individual mechanisms, which make up the proper operation of the car. The data that the controller synchronizes with itself comes from the inlet channel (more precisely from the throttle and air flow meter), from the engine block (i.e. from the knock sensor), from the cooling system (from the temperature indication sensor), from the exhaust system (from the lambda probe) and from the ESP and ASR sensors.
Car engine chips
Chip tuning is becoming an increasingly popular method of increasing engine power, which is decided by the drivers. It consists mainly in extracting the hidden capabilities of the vehicle already in the production process and significantly increases the comfort of traveling, giving the smoothness of driving and improving its dynamics by optimizing the operating parameters of the drive device.
The process of engine modification requires changes in the factory software of the engine control computer. In order to be effectively carried out, it should be preceded by a specialist examination of the technical condition of the vehicle and carried out by experienced professionals, who after the completion of all activities meticulously check their impact on the functioning of the car, and thus the safety of its users.

Requirements for repair and modification of engine controls
Due to the fact that all procedures performed on the engine controllers are a significant interference in the operation of coordinated mechanisms, they should take place:
with the use of modern tools and equipment (e.g. dynamometer),
under the supervision of specialists whose knowledge and experience allow for proper diagnosis of the problem and selection of corrective actions,
sufficiently early, since only regular maintenance of the vehicle will allow both minor and major defects to be remedied in good time,
by actions performed reliably and accurately by professionals who scrupulously perform preliminary discernment, and then skillfully confirm or exclude hypotheses to properly deal with the repair of the demanding mechanical part of the car.
We also recommend the article entitled “Is chip tuning safe for the engine?
Independently undertaking any interference in the computer controlling the engine is not only difficult, but also dangerous, because it can lead to very costly, and sometimes even irreversible irregularities in its operation.
Knowledge of the importance of engine drivers for the operation of the vehicle, the procedures to increase its power and the conditions required to repair or modify this mechanism is very valuable. A conscious driver makes an initial diagnosis of problems easier, treats the engine wisely and entrusts all activities eliminating defects to specialists. Thanks to this, it increases the life span of the car, its functionality and its own safety.
