OBDII type computers have the “chip” embedded 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 a 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 the computer purchased from us with your specific VIN number for the latest updated calibrations available for a stock calibration.This is important to ensure specific vehicle programming and to guarantee flawless performance in your vehicle.
