If you mean is the engine managed by a computer (IE injection timing, firing timing, ratio of the air fuel mixture etc) then yes it is computer managed.

When people modify an engine and they say it is "chipped" then normally they are referring the engine management main chip (also sometimes called the engine mapping).

and strictly you could call it a CPU, but EMU fits better : Engine Management Unit

Overdrive ford focus


run the fault codes and see if there is a TCM related problem in the box. Use a code reader to reset the CPU program as removing the battery terminal all the time only corrupts an already corrupted program
