On all modern vehicles there is a computer that controls the way the engine operates, this computer is called Electronic Control Module, or ECM. The purpose of the ECM is to maintain the engine running within emissions limits and at top efficiency. With the very strict emission regulations of today, this is not an easy task to achieve. Precise and constant adjustments to match various conditions of the engine must be made by the ECM in regards to speed, load, engine temperature and others.
