ForzaTune 4 is available for purchase on the App Store. Here is the link…
Use this new app to get a great foundation for your suspension tune as quickly as possible.
Frequently asked questions:
Q. What is Tune Stability?
It’s an easy way to add more oversteer or understeer. Lower the percentage to make your car have a little more oversteer. I will be turning this into a simple slider that lets you go over 100% (increasing understeer in the process). EDIT: Version 4.0.1 has this update and is currently awaiting approval!
Q. Why do you only have RWD, AWD, FWD? Does engine position matter?
Engine position is not needed with the way these calculations are designed. Our tuning genius Feuerdog devised a way to make it even simpler using weight distribution. Simpler is better (and faster!).
Q. First time I load the app I get some crazy numbers for the springs, camber, etc…
Simply close the app and reopen it to fix this issue–it will only happen the first time you download. Version 4.0.1 will be out this week to fix the small glitch.
Thanks again for the great comments, ratings and overall awesome support from the Forza community!

Here’s a quick update on the app:
