I recently chased down a decent 302/T5 out of a scrapped '92 at local junkyard. Unfortunately, someone had already nabbed the computer out of the donor car, so I don't know which one I need. I have the VIN off the donor car if that is at all useful. Thanks for any help you can give me!

The Mass Air computers from 89-93 are interchangeable with a few exceptions. Just be sure you use the MAF & MAF sensor from the same series computer. The auto transmission computers use a different start circuit than the manual computers. You can use an auto trans computer in a 5 speed car with no problems or changes.I have done it in my original 89 Mustang GT, and I know it works OK. I have no positive input or comments on using a 5 speed computer in an auto trans car. I personally would not do it.


The odd duck is the 93 Cobra computer, labled X3Z which is interally calibrated for 24 lb injectors. Try and avoid it if you can.
