The engine control module basically controls the intersection of the engine 's necessary ingredients to make energy -- fuel, air and spark. That sounds simple, kind of in the same way an engine itself sounds simple if you break it down into really basic terms.

In a modern vehicle, the Engine Control Unit (ECU) is a small computer that controls the way the engine works. It maximizes the efficiency and performance of a vehicle by adjusting the fuel-air mixture and ignition timing. This guide will explain why a modern ECU is so important, look into its history, and describe how it functions.
The emission control system in modern cars consists of a catalytic converter, a collection of sensors and actuators, and a computer to monitor and adjust everything. For example, the catalytic converter uses a catalyst and oxygen to burn off any unused fuel and certain other chemicals in the exhaust.
