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 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 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.   There is no core charge with this listing.   This is a great opportunity to own a spare ECM.** **\*\*\*\*\*\*View our e-bay store for more PCM's.** **Many different names have been given to the engine computer since its inception over 30 years ago.   Engine computers may be referred to as ECU (engine control unit), ECM (engine control module), PCM (power train control module), Brain Box, ECC (engine control computer), VPCM (vehicle control module), or Fuel Management System.   For clarification we refer to an engine control computer as an PCM.** **If you are looking for a different PCM / ECM / engine computer then please check out my other items.** **\*The picture is a representative of the 12576106.   The visual condition will be of like quality.**
