 ******GM installed this 12576106 PCM in all of the above applications.  This was possible because each of these models received their specific programming from the factory.  In other words, you can't simply swap a used PCM from one vehicle to the next.  We are a licensed user of the same GM software that a GM garage would use to reprogram and update your computer.  With your purchase we will reprogram the ECM, with the latest software updates available from GM, to your specific vehicle using your VIN (vehicle identification number).

 

 

******This computer is used and was removed from a running salvaged vehicle.  This ECM comes with a 1 year replacement guarantee.  We have been in the ECM business for 22+ years.  We are also a 22+ year eBay member with Outstanding positive feedback.

******All of our listings are of items that are on are shelves ready to ship.  There are no delays.

Why buy your spare ECM from us?  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” imbedded 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 auction you will need to provide us with your VIN number.

 

The core charge alone for the 12576106 PCM from a GM Dealer will cost you more then our total purchase price.  There is no core charge with this auction.  This is a great opportunity to own a spare ECM.  Bid now and save.

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 ECM.
