Well, to start with, I'll give some background. After 85, the cars have unique wiring and sensing systems. The 87 widebody cars, which are mostly like the 88-89's with a few exceptions, namely the actual ecu box. The 86 cars simply aren't hooked up the same, and to my scattered knowledge 85 -like your car- down to maybe even the 83's are all wired about the same. 82 1/2 has even different wiring! It's kinda weird and I'm still learning about my 87, but you catch the drift. These cars arent camaros, they changed a lot year to year, and with little changes come different wiring schemes. Perhaps an 86 flatbody computer would do you some good? Don't take that from me though, ask a flatbody owner. Point is, if you try putting an 87 or later computer in an 85 down car it will chug up to about 400 rpm and fire a few times, then collapse. I tried it when I had some problems with one a few years ago... it made things worse.
