An Engine Control Module (ECM) in a car is a computer that manages the engine's operation. It receives input from sensors, processes the data, and controls fuel injection, ignition timing, and emission systems to optimize performance and efficiency. It ensures the engine runs smoothly, improves fuel economy, and reduces emissions. #EngineControlModule #ECM #CarTechnology #AutomotiveEngineering #EngineManagement #VehiclePerformance #FuelEfficiency #CarMaintenance #AutoRepair #EngineOptimization #
