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 with the latest calibration from Toyota. This ECM will NOT need programming. Also, the immobilizer system has been reset to accept your car keys right away. It is ready to install and use right away!


We have noticed that most of our competitors are asking for a similar or greater price for this ECM models and the ECMs they sell are not tested, not updated and not even programmed, so if you buy from them, you will need to spend extra $$$ in most cases for making it work with your car.
