there's a list of "1.5" cars.... meaning built before OBD2 was required, yet they are capable of doing pretty much everything OBD2, with or without the OBD2 cert sticker.

Update : all my stuff is in. Wound up with the apu1 instead of the ostrich. I think that will be better in the long run.
G4 adapter is all set up. Just waiting for the fuel tank to come back from the shop to re install and try to get it fired up. I got the modified bin from Ryan at gmtuners. Very happy with his prompt service. I'm going to look at the bin files side this week to see if I can suss out the differences. Thanks again for the help and encouragement.

Hello everyone. I was wondering if there was an update on this post. I am working on an identical set up (3800SC series II with a 16183247 PCM installed in a manual transmission Fiero). I have the car running but I have some things that still need work. I currently have a camshaft sensor and tranny temp DTC to correct. The engine appears to be running rich and it hesitates/misses around 4000 rpm when the boost solenoid kicks in.
Is there any guidance on how to eliminate the auto tranny codes and the reduce the fuel mixture? It isn't obvious what table in TunerPro should be used to adjust the fuel constant.
If it were me, I'd go to Ryan Gick - gmtuners.com - email - sp1@gmtuners.com, and he can give you a chip already properly programmed for your application. $90 and you are set. Even if you still want to play with it after, it gives you a good starting point.
Do you have your MAP sensor connected to the vacuum at the lower intake manifold, the tap right below the supercharger snout, not any of the vacuum sources between the SC and the throttle body.
Most people disconnect the BBV and affix the valve closed. The BBV when open bypasses the supercharger and effectively turns it off.
Did you keep the ICM wiring as stock?
I make swap harnesses for 3800s (and other engines) for Fieros. http://reddevilriver.com
Have you hooked up your TunerPro RT OBD1 scanner to it yet?
I currently have a boost gauge connected underneath the snout. The ECM diagrams, which were provided by GMTuners, for the 16183247 do not indicate a MAP sensor is used with this set up. Am I missing something with this?
The ICM harness is pretty much stock, except I added some length to it, so I could remote mount the ICM and coils. I just repeated a pin to pin check, and everything checked out. It seems unlikely that the cam sensor would be bad, but I haven't changed that yet.
I think I'll try driving with the BBV disconnected.
I have logged some data from the OBD1 with TunerProRT, which is where I saw which DTCs were present. I could post a log file if that would help.
Bringing this thread back to life.
I'm wondering if anyone can post a stock 94 ~ 95 3800 Supercharged .bin file. The 16183427 PCM I have has BCC BKZS, which I'm thinking is not correct for the 94 ~ 95 3800 Supercharged engine.
Thanks,

Robert is the man to ask for that if he does not see this thread.
Is this PCM a flash or Memcal?

it's a MEMCAL unit, the 94-95 used the "gen2" MEMCALs that were about half the length of the normal ones.
i have BKZS showing up as a 95 riviera w/L67, 4T60E and a 2.93FDR.
original PCM part number is showing as 16197428, though i don't know if there are any significant differences to the one you're using now, i'm not finding 16183427 as a valid part number? i'm getting that part number as a 94-95 rolls royce "flying spur" PCM??? odly enough, that is a delco produced unit.
for 94-95 L67 BINs, i have BBTD(94 H-body), BHDR(94 C-body) and BKKH(95 H-body).
I have a 16183247 BBTD that I could read for you. I believe that is for a 94 L67.
edit
You beat me to the punch.
I transposed some of the PCM numbers ... 16183247

I found some interesting information ... Maybe BCC BLAA is for an L67 with manual trans.

must be a typo..... GM never released a L67 vehicle w/manual trans in the US. australia probably received quite a few, but then you're dealing with a whole new PCM/mask.
if you find a BIN for a L67 w/manual trans for any application, it was either created by someone after the fact or a leaked GM prototyping calibration.
the only manual trans 3800s i can even think of in the US were the F-bodies and those were all OBD2(the 95 3800 F-bodies were all automatic and used an early OBD2 PCM).
Just looked at Cal Data and BLAA is listed as a 3.8L Man... but the trans is a M13 4T60E. So there's some typos going on...
