I have a 93 PA Ultra Supercharged, bare stock. Just put a 94 block/heads in my car with stock 93 blower etc. Runs HARD and has kept up with a series 2 with a pulley drop. I have a spare PCM froma 92 PA ultra supercharged I found in a salvage yard, also have 2 superchargers with the epoxy rotors (94-95) and a 2.5" pulley that i want to run to really show some punks what my boat will do, what needs to be done to the pcm to give it some extra pep and handle the new blower? Or anything I thought about just putting it on and seeing what happens. Thanks in advance

Intense Racing or ZZP Racing can do you a PCM. Dropping to a 2.5 means shaving the supercharger snout. It will wake up or fold up the old girl.....

John, from the looks of it, they only work with PCM'* that are 1997 or newer. Sounds like they both use HPTuners for PCM programming(1996 and earlier are not supported) Though, the earlier PCM'* are reprogrammable, I don't know of anyone that does it mainstream. Not much of a market for them. That is why I always suggest to people to get something 97 or newer.

you have to find someone who still does chip burning and knows the Bonneville, few and far between now

If you do not have the ability to check things like fuel trims, and scan for knock, then I'd not suggesting just throwing it on there and seeing how it runs, unless you have the money to replace the motor if you ruin it.
IMO you should never do any HP adding mods if you cannot scan, and tune afterwards, I am no expert on tuning though.

Unforunatley William is correct. Doing big HP mods without the ability to scan is destined to doom.

I have access to a Snapon "brick" scanner that reads OBD1 on this car, im going to be hooking it up anyways as it all of a sudden is having an extremely rich running condition at the moment Suspecting MAF (has new o2, temp sensor, intake gaskets including supercharger gasket, plugs (autolite 104) and wires. Same issue i had when i first got it running a few months ago when it was my MAF screen being removed that caused it but its still in tact and doing the same thing.

I believe my NEW plenum (supercharger gasket) is leaking causing the lean condition that is making it DUMP fuel through the system, When i installed motor with this new rebuilt blower the plenum seal felpro brand was used to seal it to LIM. when i spray carb clean around the blower case it starts to run better. Why would it leak with less than 1k miles on it? Should I have used some high heat copper RTV as well?

when you take it off you will have to check the lower and supercharger to see if either is warped. did you use the lower from your old engine, replace gaskets?

heres a free tuning program that should work for the series 1 3.8 just need a labtop its what i plan too use this season TunerPro and TunerPro RT - Professional Automobile Tuning Software
