Ok heres my question.Is the 94 3.1 Z24 a reprogramable type pcm or do I have to replace the chip?I have looked at all the chip sites and nobody has one for a 94?Any help would be great.

It is a replacable chip / PROM.

So it is the same as my 91 Z24?

94 3.1 J bodies and the 94 lumina still used the removable memcal.

So I can replace it with a 29C256 chip correct?What is the best program for modifing the J Body ECMs?

Yup, you can put that chip on the memcal. I use winbin but I also made the file. gmpcm.com and tunerpro.markmansur.com are the 2 other programs I have used. Not sure if tuner pro has A1 though.
