The engine controller, or more precisely the electronic module controlling the operation of the internal combustion engine, relies among other things on the data stored in the on-board computer (it displays maps or data tables based on which the engine controller can coordinate the operation of the engine). As you can see, it is a very important part of the whole motor vehicle, without which its correct operation is not possible.
This is because the engine controller collects, compares and also coordinates the data coming from all the sensors in the vehicle. From the intake channel (with an air mass sensor or throttle), from the engine block (here the data is collected from the knock sensor), from the exhaust system (the well-known lambda probe), from the cooling system (in this case, the temperature sensor is responsible for this), and from the ASP or ESP sensors.
What if the engine controller is damaged?
The engine controller is a very complex component the repair of which is very time-consuming and therefore also expensive. Therefore, in the vast majority of cases it is simply worth buying an engine controller on your own.

Therefore, it is worth buying the same device, but already used. Its price will be less than half, which should convince you to buy one.
In addition, you will be satisfied with the final result because you will receive a functioning and previously tested device that has undergone servicing and is available for sale.
