We sell Pre-programmed used, new & remanufactured engine computers that are programmed using your VIN so that you no longer have to go to a dealership or auto repair shop to replace your engine computer.

To find the correct engine computer for your vehicle it is best to use the "service number". This number is on the I.D. label on the computer itself. It might be abbreviated like "service no." or "serv. no.". You can put this number in the search bar and the computer for your vehicle should come up. You can also search using the year and model vehicle. Using this method you might find that several choices come up. This is because several different service numbers may have been used for the same vehicle.

The service number applies only to GM vehicles. It is referred to as the “part number” on Chrysler vehicles. Many Chrysler vehicles have had a software update at some point. If that has happened another I.D. sticker will be put on the computer that says “software update” and then a part number. The software update number will supercede the original part number and is the number to be used for reference.

We will always need your VIN (17 digit vehicle identification number) so we can reprogram the computer before we ship it to you. This number can be found at the lower left of the front windshield or on a label inside the drivers door area. It will also be on your title or registration. Please look for a confirming message from us that the VIN is good. It is not uncommon that there is an error with the VIN. Only the correct VIN can be used.
