Engine Control Units (ECU)

How to choose an engine control unit

The engine control unit (ECU) controls injection, ignition and the throttle based on sensor signals. A replacement is chosen by the electronics manufacturer's number and the OEM number on the label, because one car model can come with several ECU versions.
