the computer is programmed for each specific motor after I think 1994. Any time you switch out it needs to be sent oout and reprogrammed. Just like if you order a chip you need to send that out as well and egt it programmed for your specific vehicle. Just like if your computer craps out you need to order a new one and send the old one so they can transfer everything over. Not too sure why or how it works but I remember on another forum I am on that they are programmed. So might be something to check into. If your trying to use your old computer with a new engine I am not positive it will fire up. Its just how the new computer crap is setup.
