NOTE: Correcting these values for Diff swaps/changes in gearing will retain SMG Function and SMG/6MT Cruise Control

Tire Diameter Factor

K_V_WEGIMPULSZAHL: Pulses/KM IE E46 is 48 pulses/ tire rotation (from hub). E30 is 9 (from Diff)

=(1000/((((((Width*(Profile/100))*2)+(Diameter*25.4))*3.14159))/1000))*Pulses

Gear Detection

K_S_GANG_X_NV_MIN/MAX

K_GANG_GRENZEX_X

Use Gearing, Speedo Calibration, GangMinMax, Grenze.xlsx

Transmission Ratios:

K_SMG_I_HA: Diff Ratio (Max is 4.25 due to MSS54/HP restrictions)

K_SMG_I_GANG_X: Gear 1-6 and Reverse
