Its functions include, but aren't limited to:
* Fuel injection: Controlling the amount and timing of fuel delivered to the engine.
* Ignition timing: Determining the precise moment the spark plugs fire.
* Air/fuel ratio: Monitoring and adjusting the mixture of air and fuel for optimal combustion.
* Emissions control: Managing systems like the catalytic converter and EGR valve to reduce pollutants.
* Throttle control: (Depending on the specific engine) Working with the throttle position sensor to regulate engine speed.
* Sensor inputs: Receiving data from various sensors (temperature, oxygen, crankshaft position, etc.) to make adjustments to the engine's operation.
Essentially, the ECM is the "brain" of the engine, constantly monitoring and adjusting various parameters to maintain optimal performance and efficiency.
