Folks, I have finally found someone who does programming on GM Pre- OBD2 systems, including the 3.4 V6 !


I'm using a 94 Camaro 3.4 with a 4L60E trans, and he told me he will be able to re-set the lock-up and shift points to suit my car when all the details like gear ratio, weight, etc have been finalized on my end.

I hope this info will smooth somebody's path !
