OEM Engine Control Modules (ECM & ECU)

Shop replacement OEM Engine Control Modules (ECMs) and Engine Control Units (ECUs) at Swan Auto ECM. We offer automotive computer modules for a variety of vehicle makes and models.

An engine control module helps manage important engine functions, including fuel delivery, ignition timing, and emissions systems. A failing ECM or ECU may cause starting problems, engine performance issues, or diagnostic trouble codes.

Find the Right ECM for Your Vehicle

Browse our inventory using your vehicle's year, make, model, or OEM part number. Always verify the part number and compatibility before purchasing, as similar-looking modules may not be interchangeable.

Some replacement ECMs require programming or vehicle-specific setup before installation. Check the individual product listing for available details.
