A new module is built from brand new components and materials. To make things easier when shopping for a replacement engine control module, here are some factors you should consider: ConditionД®ngine control modules come in either new or remanufactured condition. Things to Keep in Mind When Shopping For a Replacement Engine Control Module If you know what youвЂ™re doing, itвЂ™s possible to tweak the program to get the most out of performance parts in heavily-customized vehicles. Then it activates the ignition coils to transform the batteryвЂ™s voltage to the high amount needed to fire off the spark plugs and burn the fuel-air mix.ДЄside from making sure the engine parts work in the right way, the engine control module stores program instructions on the safest and most efficient way for the engine to run.

It uses the information to adjust the amount of fuel and air entering the engineвЂ™s cylinders to create the right mixture. For example, the module receives input from the oxygen sensors in the exhaust system that the current fuel-air mix didnвЂ™t burn properly. The ECM oversees the operation of various engine parts based on the information it gets from the various sensors in the engine and exhaust system. If it also controls the transmission, the module is considered a powertrain control module (PCM). Abbreviated as ECM, it also goes by other names like digital motor electronics (DME) and engine control unit (ECU). The engine control module is the electronic brain that operates the engine.
