5.0 EFI A9P & A3M1 Computers

[wraithracing]

I have a pair of A9P computers and 1 A3M1 computer. All are for 89-93 5.0 EFI cars. The P computer is the automatic computer version of the A9L for those that don't know. The A9P supposedly has a bit more aggressive ignition timing table at the lower RPMs due to the automatic, but otherwise is the same as the A9L. The information I have found says the A3M1 is a later version of the A9P used in the 92/93 cars.

All computers will work with a 5 speed setup as well as the automatic. There are some recommended wiring changes or alterations if using these in the 87-93 cars due to how the 02 harness grounds. Nothing major, but it can cause issues. Just giving everyone the heads up. Obviously these can be used in any car that has been converted to EFI or an 86 that has been converted to Mass Air.

All computers were tested on a 91 5.0 GT and worked just fine. Engine start and ran with no issues or codes present so I believe all to be in excellent working condition.

I am asking $275 each shipped in the contiguous US. Please PM me with any questions. Thanks!
