you change the axle ratios and want to match that?
the software can not change gears sets. impossible
what you can do (i have this on my JK) is change the axles or tires
the use a "tool" that changes the PCM gears parameter to match what you have, for SPEEDO corrections. and by default allows the ECU
to use the correct load factors , when driving, (very important)
i have flash cal..
they have other tools. that do more. but not for all cars.
and MPG will not work. (i bet) seen many say so after popping for $150 or more.
