Based on collected data, it sets the position of the camshafts, throttle it sets up the ignition/injection timing. Modern engines are equipped with ECM modules that gather information from the intake, exhaust, cooling system and some other internal components to estimate the running condition of the engine. But as car electronics have learned, the function of the Engine Control Module has expanded to almost every phase of operation.
