You can do a lot
Rev limiters, timing, fuel, speed limiters, injector size, turn off EGR, tons of auto tranny stuff, just about anything you want.
If you go to
www.guieectuner.com there is a freeware version of the GUI-EECTUNER software to download. Then below that there are processor files that customize that software depending on the processor family you have.
You have a Gen 2 right ? I will be working on adding support for the CUX1 and CUX2 pretty soon also. I've just got to get some Gen 1 mass air stuff out of the way first
