BG55.COM Forza Tuning Calculator

*Note: In FM7, torque is no longer listed in the Upgrades interface, but it can be found in the "My Garage" and "Select Car" interfaces. Just change the view (Y on the xb1 controller) to find it. Torque is essential to the function of the calculator (differential, toe and gearbox).

Vehicle Data Input

Enter Year, Make, & Model (optional for multi-tabs & future export)


Enter Vehicle Data for Tuning

Define preferred Damper Stiffness and suspension length of Travel
Enter Tire information. Use Same Size if fornt and rear sizes match.
Enter Power, Weight and misc. information
Fine-Tuning Multipliers

Enter the optional suspension component multiplier (1.00 is standard).


Transmission Tuning (Race Trans ONLY)

"Top Speed", "# Gears" and "Redline RPM" are all required if Transmission tuning is desired. Leave at ZERO (0) if Transmission tuining is not desired.

ADVANCED Transmission Tuning (optional)

If the values are set to non-zero, then the calculator assumes you know what you are doing. Output will be skewed of the inputs here are wrong. The input here is for custom "Final Drive", "1st Gear Ratio", and "1st Gear Top Speed".


The Tune

Below you will find your tuning results. These results are balanced starting points based on several factors (total weight, weight balance, drive type, downforce, etc.). Fine tuning will be needed to adapt to your driving style and/or preferences. If there are any issue or problems with the tune, please contact justLou72 & Beefsupreme42 on the Up 2 Speed Customs discord.
