Haha, well those are all there to adjust the feel of the wheel to your liking. For the profiler, I don't even think I did anything with it from whatever the default is. Then in game I make all sorts of adjustments since each track, mod, and game is completely different. Whatever changes you do make, do it one at a time so you feel exactly what's changing. For instance, I adjusted the force feedback in NR2k3 at 25% intervals than tweaked it from there. Of course I ended up going back to 100% because I felt it was more realistic. But that's the wonder of having a wheel. One thing I will say is that in NR2k3, it's good to adjust some of the advanced settings under the controls section. I found that my centerzone was a little too large and insensitive but way too sensitive on the periphrials and fixed it very nicely through a few of the settings in Advanced Setup. There may be some other guys who will give you generic settings and explanations but ultimately it comes down to playing with it until it feels right to you.
yeah good advice man, i set all my settings back to default and car seems somewhat stable. i guess im trying to figure out why my car always turns to the right and wants to spin out. i just like peoples input im still new to this game.....
