16172693, 16184164, 16184737 and 16196397 PCM information for 93-95 3100(except A-body) and 3.4(RWD) vehicles.
ADX will work for all 93-95 applications. XDF will work for all revision 3 BINs, which will cover all 94-95 applications and 93 3100 W-bodies. it won't cover 93 F-bodies since those were all revision 1(manual) or revision 2(auto). revision 0 is the fairly rare W-body 3.1 generation 2 SFI, which seems to only have been used on california emissions equipped 93 W-bodies. even then, there was an alternate PCM used, though it wasn't SFI.
BINs and wiring diagrams to follow.
EDIT: BINs Zip'd and uploaded here.
