wasn't aware that the computer were different. learn something new everyday.

The two most popular (abundant) in a Fox are the A9L (manual tranny) and the A9P (Auto).

All the Mass Air computers from 89-93 are interchangeable with a few exceptions.You can also use an auto computer in a manual... but not a manual comp in an auto. 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.
