Quick question on dialing in my mph reading with fast xfi 2.05 and the caspers adapter box. Im running a 28" tall tire and my mph reading seems to be off by a bit in data logs. Does any one know what the factory driveshaft rpm calibration would be. Right now the rate sensor calibration is set at as fallows .
Driveshaft RPM calib. = 1800
MPH Calibration = 730
Aux. RPM Calibration= 100
I tried the formula that fast gives and it came up with 1,596.49 for the MPH calc. with a 28" tire and 3.42 gear, something doesn't seem right to me, any insight would be appreciated.
