Hidden inside every modern car is an advanced computer that constantly orchestrates the operation of the entire powertrain. We are talking about the engine control unit, commonly known as the ECU (Engine Control Unit) or ECM (Engine Control Module). This specific module decides on the fuel injection dose, ignition timing, boost pressure, and communication with other systems in the vehicle.
