I cant seem to find one.
Are any later knock modules compatible with obd1 PCM's?
I really want to eliminate the false knock im getting at 4400rpm.
My 95 has one with Pacesetter headers. I had to tune it out of the PCM as it would get nothing but knocks from the headers and it would go nuts during the burnout. Someday I'll try it again.

if you were to swap out for a lt4 one, would there have to be any retuning or is it "put it in and done"
