OBD1 conversion Ok, I did some searching on the site for info on doing an OBD1 conversion. I got tired of reading and never did find anything helpful so maybe yall can help. Tell me if I'm wrong, all I need is an OBD1 pcm from a 94-95 LT1, knock sensor for the same and that's it?? Then get tunercat, the cable and start tuning?? And do I still need the LT4 knock module??
You do not need the knock sensors instead you can make the OBd1 pcm work with the 96 knock sensors less than $1 worth of resistors from Radio shack is enough to do 2 pcms.
