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 20+ years.

Other info: Whether you are looking for a replacement ECM or need a spare ECM for your LS1, LS6 or GEN III conversion we can help. All of our products are purchase out right. This means you will be able to keep your existing ECM and avoid any core charge. That’s right; there is no core charge with this listing, no extra return shipping charges, and no waiting for a credit. How can we do this when others can’t? It’s simple; we specialize in a very small segment of the total replacement ECM business. By doing this we can keep our cost down and pass the savings on to you. 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” 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. Buy it now and save. ******View our e-bay store for more ecm’s.
