Hello.
We are having some trouble calibrating the speedo with the HP tuner. we enabled the circumference to what the tires are but we still have the same 8% error after fitting 35" tires. we changed the drive tires, max circumference and the min circumference. we fiddled around with different values to test and see if we got any reaction. nothing. we increased all to 3500mm and nothing min to 2500, drive to 3000 and max to 3200 and still nothing. what is wrong?
