Is it possible to change the VSS/Speedometer calibration for different final drive ratios? I have an autocross only car and I run a 7.25 rear gear and a 20 inch tall tire. The VSS/speedometer reads 158 half way down the straight, and won't dispaly higher than that, even when I set the upper limit to 999 in K manager.
I am VERY satisfied with my K Pro.
Thanks, Del Long
