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 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.
