How Does the Engine Control Module (ECM) Function and how to Remove and Install on BMW Z3?

The Engine Control Module (ECM) is the computer control module. The engine control module uses the Mass Air Flow to take care of fuel delivery and ignition time of the vehicle's engine. The ECM boosts the fuel mixture by adjusting the opening and closing time of the fuel injectors and when removing the ECM, let the E30 and E36 models reach normal temperature before you change the ECM to prevent poor performance.
