ECM (Engine Control Module) controls the entire engine as if it were the soul of the engine.

Expanding information:

1. Under normal operating conditions, the engine is closed loop control, and when the throttle opening is too large, rapid acceleration and cold state, the engine will enter the open circuit state. Especially in the big foot throttle, the engine is not only in the open circuit state, but even enters the fuel injection thickening mode, so it must be more fuel-efficient.

2. The engine electronic control module (ECM) has the function of continuously monitoring and controlling the normal working of the engine. In modern engine management systems, ECM is the core control component. It can provide the best air-fuel ratio mixture and optimal ignition time to the engine according to different operating conditions of the engine, so that the engine is always in the best working condition, and the performance (dynamic, economical, and emission) of the engine reaches the maximum. good.

3, the engine control assembly fault code, ECM is also called ECU, it refers to the electronic control module on the car; such as the body computer is generally called BCM, the engine is called ECU, the gearbox is called TCU.
