There’s a Gran Turismo application (or program to someone my age) for the iPhone. It’s called GTune5 and is an app that should make the tuning of cars easier.
I think the idea is that it will give you settings based on a car set up you like and translate them to other cars. So, I like some oversteer in my cars and the app will allow me to recreate that in other cars once I enter the details for a car I can really handle well.
Lovely. Now I just need some time to play the game!
