I have a PCM from a 1995 Caprice wagon. This had the 4.3L Lt1. I have put a 5.7L LT1 into my 1991 firebird. I found online somewhere a BIN file from a 5.7L Firebird. I used Tunercat to send these values to the 4.3L LT1. The car runs pretty good but has some choppy-ness on accelleration. I am guessing this is because the Firebird/Camaro 5.7 LT1's and B-body LT1's were slightly different.
I bought a PCM from a junkyard that was to a 1994 5.7L Roadmaster, which matches my engine. Thing is, when I went to write the settings to my PCM, I noticed the CYLINDER VOLUME is set at 0.00 ml/cyl. Also Injector Flow rate is 793.46 lbs/HR. It looks like the values are shifted. I read the PCM twice and got the same results.
Does anyone have a stock BIN file from a 1994 or 1995 B body car PCM? I would just research these 2 values but I am wondering what other values may be incorrect or even missing in this PCM.
Any help guys?

I like to use Ludi's site Ludis's Home Page to track down car models and use it to ID the corresponding program... then go to Moates (or TC) and download the appropriate files.
