Hey guys, I just wanted to get caught up on what's going on with the OBDI and OBDII PCM's latest tricks.
I have the OBDI convertion on my 1996 Z28. I'm refreshing my 383 with new rings, cam, valves, and additional port work, and the shop that is doing the work -my friend Peter- can do a great job on OBDII tuning. (Dyno-tuning onsite).
My question is, should I stick with my OBDI convertion, or should I go with the OBDII programming?
Thx-Goose

 

If you don't have to pass emissions, stick with the OBDI.

 

I take it there hasn't been enough progress on the OBDII world in the last 3 years or so, that would make a choice like this, a toss up?
My car is set up so that either the OBDI or the OBDII are plug-and-play. OBDI has the knock sensor mod so, I can still have the 96 KS in the motor, and 02 simms on the rear cats.
Wondering, if more power can be squeezed on one over the other when it comes down to a dyno-tuning.

 

If your friend only has OBDII tuning software, you could get it dynotuned on the OBDII, then copy over the air to fuel ratio to the OBDI.

The OBDII can be programmed just as the OBDI, but it is more picky and I personally preffer OBDIs.
