Created by Basement & Garage (justLou72)Additional Assistance and Testing by the Up 2 Speed Custons (U2SC) Community. Tested with and intended for Forza Motorsport 7 and Forza Horizon 4. This calculator will work with FM5/6 and FH2/3 as well. If you are looking for something to work with X360 Forza titles, check out the Classic 1.6 version; however, the main calculator should work with FM4 and below.
