Google Play Review

"I've been tuning some of my cars with your calc, it works very well even beat some of my PB times. [...] you really have the muscle car tuning down, love it. Thank you very much for the time you put into making this available, well worth it and I hope more people take notice."

Q: Why do you claim QuickTune FM6 is the "most advanced" Tuning Calculator?

A: Because QuickTune FM6 does not use a generic base tune for all cars like existing tuning calculators. Instead it uses a specific base tune for each car type and drivetrain. There are about 40 car types in Forza Motorsport 6, each available in average with 2 drivetrains which makes it up for around 80 bases tunes. With that approach QuickTune FM6 can calculate perfectly balanced tunes for each car that don't need to be tweaked afterwards.

Q: What do "Standard" and "Balanced Aero" settings mean?

A: "Standard" settings are calculated Tune settings based on the provided as-is front and rear aero levels. "Balanced Aero" settings adjusts the rear aero level based on provided front aero level and the cars weight distribution to have a balanced front and rear aero during cornering. "Balanced Aero" settings are only available if the rear aero kit is adjustable.

Q: Why do calculated ARBs and spring rate values don't match settable in-game values?

A: QuickTune FM6 cannot reliably determine in-game fraction digits for ARBs and spring rates. Therefore ARBs and spring rates are provided with 3-fraction digits. You need to set it to nearest in-game value.
