How do you change gear ratios, o2 sensors, etc on this tuner? when I upload the 87 octane tune, do I have to change the paramiters to change this other stuff? I can't seem to find it anywhere on the tuner.

RTM, and just get the tuner in your hand and use it. Its pretty simple

ok, I figured out how to do that stuff now, pretty simple. Just one more question, is there any way to turn on\off the rear O2 sensors? I couldn't find that anywhere on the tuner. I told Brent when I ordered the tuner that I was getting an offroad h-pipe, so I'm pretty sure he programmed for it, but not 100%. The headers are goin in Friday, and I really don't want any check engine light codes appearing.

I have been told that it cant be done with the SCT tuner, but the diablo allows for it so to me that makes no sense for the SCT not to have this feature.
