Why buy your spare PCMfrom us? You will be purchasing a high quality used PCM. You get free Flash programming with every OBDII GM computer purchased. OBDII type computers have the “chip” imbedded into the PCM 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 PCM whether it is a used PCM or a remanufactured PCM. 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 program your computerpurchased from us with your specific VIN number for the latest updated calibrations 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 auction you will need to provide us with your VIN number.


There is no core charge with this auction. This is a great opportunity to own a spare PCM. Bid now and save.
