You will be purchasing a high quality used ECM. You get free Flash programming with every OBDII GM computer purchased. OBDII type computers have the “chip” embedded into the ECM and it is not removable. The calibration file per the application is “Flashed”, or reprogrammed using a software package and a pass through device. The “chip” is no longer removed for programming. Proper programming is essential when replacing an ECM whether it is a used ECM or a remanufactured ECM. A used GM computer will have the software installed that pertains to the original vehicle that it was removed from. In some cases GM OBDII type computers will interchange with many different vehicles including those with different engine and transmission configurations. However, unless the computer is programmed with the correct software it won’t function properly upon installation. We will flash reprogram any OBDII computer purchased from us with your specific VIN number for the latest updated calibrations straight from GM for a stock calibration. This is important to ensure specific vehicle programming and to guarantee flawless performance in your vehicle. At the end of the listing you will need to provide us with your VIN number. The core charge alone for the 12589463 PCM from a GM Dealer will cost you more then our total purchase price. There is no core charge with this listing. This is a great opportunity to own a spare ECM. Bid now and save. ******View our e-bay store for more ecm’s.
