ECU ECM ECU

ECU (Electronic Control Unit) and ECM (Engine Control Module) are integral components in modern vehicles and machinery, managing and optimizing various systems' performance. The ECU is a general term for any electronic control unit that manages specific functions such as engine control, transmission, and other critical systems. The ECM, a specific type of ECU, is primarily responsible for controlling the engine’s performance by regulating fuel injection, ignition timing, and air-to-fuel ratio. These modules ensure efficient engine operation, improve fuel efficiency, and reduce emissions by continuously monitoring and adjusting various parameters in real-time.
