So, the difference is that a ‘PCM’ controls both the engine and transmission system , whereas an ‘ECU/ECM’ or ‘TCM’ controls only one of these systems. The processing power of the PCM (or similar control unit above) allows for the control of a host of interlinked sub-systems in the vehicle providing optimal gear shift, engine performance, timing and fuel efficiency.
An ECU (Electronic Control Unit) or ECM (Electronic Control Module) are both terms to describe the ‘brain’ of an electronic engine. An ECU is a type of computer , which takes a variety of inputs from sensors on a diesel engine and uses the information to control unit injectors or the engine actuator .
