IMPORTANT: You probably have learned that “Used ECMs need programming“.  It’s true. When you buy a used ECM, you will also need to spare time and money to go to a shop or dealer for programming your ECM. Otherwise, the engine of your car will not start.

BUT,  WE’VE GOT YOU COVERED! This unit has been repaired, refurbished and pre-programmed. This ECM will NOT need programming. It is ready to install and use right away!

Most of our competitors are asking for a greater price for this ECM and the ECM is not even programmed, so if you buy from them, you will need to spend an extra $100 on programming for it to work in your car.

NOTE: Please, before ordering, make sure your actual ECM part number matches the part numbers offered in the list below.
