Re: Identifying MPI computer
'82? No EFI on Jeeps that year! What does it look like? Black plastic with 3 mounting screw holes and a 60 pin connector is the type used in '91-'95 MPI 4.0s. If the tag is missing, the only way to read part number is to plug it into a vehicle and read the number with a DRB scantool. There are probably 50 different 4.0 controllers that look the same, along with 100s for 4 cylinder, V6s, V8s, V10s, ETC. based on the same SBEC controller! Ther is no chip to change calibration, either. Get a guarantee, or don't buy it. Otherwise, it's good for a core on an exchange rebuilt unit. Hope this helps, good luck!
