The Engine Control Unit (ECU) is a critical component of modern vehicles, responsible for controlling various engine functions. Key aspects managed by the ECU include fuel injection, ignition timing, idle speed, and emissions control. By continuously monitoring sensors and adjusting parameters, the ECU optimizes engine performance, fuel efficiency, and emissions. ECM: The ECM is similar to the PCM but may have a narrower focus on engine-related functions. It monitors and controls various engi...
