Im a member of http://diy-racetuning.net/index.html. This place is FULL of invaluable tuning info if your tuning nut like myself. The resources to the left on the front page are absolutely worth a read if you tune. Most of this stuff was written before FM3 came out, but is based on real world tuning and should apply to FM3 as the physics are darn close to spot on. Ive had pretty good luck using the methods described there. They do all use the controller and sometime the tunes dont translate well to the wheel. FYI: I beleive Feurdog was one of the pioneers of DIY and sometimes asks for feedback with his calculator.
So fire up your printer and put some reading material next to the throne.
Just so you know, It goes without saying that any team related tunes will NOT get posted on the DIY websit
