You're probably going to end up at Moates.net, pick up the APU1 autoprom package. It's for GM only, OBD1 thru '95, it's the entire emulation assembly, you'll need to familiarize yourself with it but it will flash the prom as needed.
I wish @RobertISaarwas around, he could tell you this pretty easily. Is this a 3.1 MPFI or a 3100? I vaguely remember it was a mid-year switch. Or I'm just getting generally confused. If it's a 3.1 with the old school dumb OBD-I ECM, it would be an easy enough reconfiguration.
The 284 has slightly steep gears for a 3.1, I'm assuming you're using it just because it's all you can get?
Hi I need advice on PCM for my 94 olds cutlass. Currently has the 3.1 and I'm swapping in a 284. I'm looking for help in figuring out if I have to flash the PCM if so what program do you suggest and also what .bin should I use? Is there someone I should try to get ahold of? Etc. Any help would be great thanks in advance
Strut tower braces are about the same thickness, and yes the monoleaf is a pain to deal with but replacing those outer pucks is a must if wanting to keep it handling right. New subframe mounts and rear adjustable lateral links help out a ton as well.
