Shopping for Engine Control Module

Engine Control Module Shopping Info

What is an Engine Control Module?

The engine control module is the electronic brain that operates the engine. Abbreviated as ECM, it also goes by other names like digital motor electronics (DME) and engine control unit (ECU). If it also controls the transmission, the module is considered a powertrain control module (PCM).

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. For example, the module receives input from the oxygen sensors in the exhaust system that the current fuel-air mix didn’t burn properly. It uses the information to adjust the amount of fuel and air entering the engine’s cylinders to create the right mixture. Then it activates the ignition coils to transform the battery’s voltage to the high amount needed to fire off the spark plugs and burn the fuel-air mix.

Aside 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. If you know what you’re doing, it’s possible to tweak the program to get the most out of performance parts in heavily-customized vehicles.

Things to Keep in Mind When Shopping For a Replacement Engine Control Module

To make things easier when shopping for a replacement engine control module, here are some factors you should consider:

Condition

Engine control modules come in either new or remanufactured condition. A new module is built from brand new components and materials. Meanwhile, a remanufactured module is an older but perfectly usable computer that went through a thorough upgrade process to let it compete with more modern parts.

Remanufactured modules are just as good as newly-made counterparts, and they are a great budget-friendly option.

Product Fit

Most engine control modules are designed for a specific model. Installing a direct-fit part should be straightforward; it will fit in the same space as the old computer and use the existing connectors.

Universal fit ECMs are compatible with multiple vehicle models. Depending on the design of the module and vehicle, you may need to perform some modifications.

Whatever the product fit of the ECM product, always make sure it’s compatible with your vehicle.
