Up 2 Speed Customs (U2SC)

Racing together since 2011, Up 2 Speed Customs is a close group of "Average Joes" who love all aspects of the Forza universe. This tuning calculator is built and maintained by U2SC Members for U2SC members to use in Forza Motorsport & Horizon on Xbox One, and we gladly keep this open for anyone to use. We do not charge for access or make any money from ads (nor do we plan on it). Please provide feedback on the tuner HERE. Your feedback is important to us!

Vehicle Data Input Form


All of the data input below (except the "Tune Name") is used to calculate the base tune, so please enter all of the data correctly. Remember that this is a BASE tune. There will be fine tuning needed to mate the base tune to your driving style. The Transmission data is optional. If you don't want to tune the transmission, then leave those fields alone. Your suspension tune will still calculate without the additional data.
Basic Vehicle Data Points (Imperial Units)
Enter Year Make Model Class PI (optional)
Only choose "Stock" if 1st upgade is "Street"; otherwise, choose 1 option below 1st available upgrade to represent "stock" in game.

Suspension Fine Tuning (Optional)

Optional Input: 100% is the default tuner output. Since the tuner is built on the 80/20 rule, it might be necessary to adjust the suspension while maintaining a balanced output. This is especially helpful when tuning older vehicles, vehicles that tend to tripod, and vehicles with exteremely low/tall ride heights.
