The Engine Control Module or the ECM is considered as one of the top-tier quality and most reliable, which is tasked to regulate the operations of the DeVille engine in a variety of Cadillac models. This is a more sophisticated ECM not only controls such parameters as engine speed, oxygen and throttle position but also controls parameters such as the air fuel mixture and engine's idle speed. Managing all the information about the Cadillac DeVille Engine, the Engine Control Module controls the quantity of fuel delivered and ignites the ignition coils for better combustion, thus making it efficient and safe. Cadillac has gradually moved from the first forms of integrated circuits to even microprocessors used in the vehicle's ECM for enhancing the control of such functions as variable valve timing or transmission operation. Such changes have entrenched Cadillac DeVille as a performance luxury car that continues to make evolutionary changes. Subsequent generations of the DeVille, particularly those of the new millennium, have had features like a night vision system and stability control among other things which make it easier to drive. A perfect example is the Engine Control Module that has created stigma in the market due to its versatile performance during handling of different driving situations and has not dragged the Cadillac brand from the production of luxurious cars that meet the market's demand for innovation. Thus being strongly connected with various models of Cadillac DeVille the ECM has a great responsibility to provide each Cadillac DeVille to be a representative of Cadillac's powerful, smooth and safe character which has been long known around the world.
