5B7 just doesn't exist... i don't know if that was an oversight by tunercat or what, but all 94-95 3800 S1 vehicles are 5B. datastreams might be different(haven't looked in a while), but the "masks" are the same between supercharged and naturally aspirated.

i would need to source an OBD2 connector...
