I'm not sure what you're saying. I happen to be tuning an Adrenalin.

Does anyone know the values in the formula of the Excel sheet attached? Trying to change it for my final drive ratio and tyre size
This is the formula in the sheet.
=(B23*13.6*0.00595/3.55)
I know 3.55 is the final drive ratio, wondering about the others.
The math in this should make more sense. You can enter your tire circumfrence, or revs/mile from your calibration and it should populate the correct MPH.

If I had to guess what those numbes are:
13.6 is the radius of the tire in inches
.00595 is half the invese of circumfrence in inches.
