Long story short, I am looking for a new computer for a '97 Z28 after my Hypertech messed up my current one. (program was interupted during reprogramming and now even the dealership can't even scan it) Anyway, I am wondering if I should switch to an OBD-1 CPU since I have to get a new one anyway. I have been told that it is much easier to find tuning software and to tune OBD-1 CPU's. Any advice would help as this is really the first time I have delt with any computer issues. Thanks.
