Hypertech programmer III question?
It can be used to change tire size, gear ratio, shift points (auto), rev limiter, and removing the speed limiter.
And 96 & 97 use the same unit.
Get a mail-order tune, you can get all that plus a more effective tune for increased power.
Best of luck.
I agree with koolaid as far as how useful they are though. If your going to mod your car to the point of needing to be able to tune the motor, they are a waste of money. Even if you just add headers you will need more capability. But they are ok if you just want to adjust trans settings on an A4 factory car, or with a mild converter. Pretty much useless for a M6.
