ECU is usually an Electronic Control Unit. Some OME's name one of there ECU's, Engine Control Unit to make stuff more complex. Not app manufacturers have Engine Control Unit or a Body Control Module. The electronic architecture of a Volkwagen, GM, Volvo or Tesla is very different. Hardly any of the ECU's have the same name.

It looks like Wikipedia agrees with me and in addition, the Engine Control Unit article state that they are usually called the Engine Control Module (ECM) to lower confusion. https://en.wikipedia.org/wiki/Electronic_control_unit https://en.wikipedia.org/wiki/Engine_control_unit

Different OEMs vary in architecture and naming. Making it a bit of a hassle working in a teir-1 with multiple customers.

Or PCM (powertrain control module, since the transmission and engine typically work as one unit) which has been used by Ford (and Mazda) since ODB-2 was standardized in the 90s.
