I am trying to adjust the speedometer for different tires. No changes that I make are reflected on the speedometer. What am I not doing here. I am working on a 2010 corvette zr1. Any help would be greatly appreciated.

Are you checking the speedometer on the road with a GPS? Is something going wrong with the program and nothing is changing in the file? More details please.
