You must be correct, but I think I remember seeing a box on the Edit showing gear ratio, was that for something else? I've never used it, I just have a copy to see my tune...IT L GO said:Not true
C5s speed is measured by the rotation of the output shaft. LS1 Edit Menu specifically says recal is not required when changing gear ratios. However, it is required when changing tire size. :cheers:
