I gave a few thoughts for this since this didn't occour to me with G27 until i tested E-Kart last night. First it didn't feel good, so i increased the FFB multiplier to 4.00. Just entering the pits made the wheel go crazy, not just rattle but huge turning back and forth. Driving straight actually reduced the rattling and constant turning a bit but still it was too much.
So i decreased the multiplier to 3.00, this actually helped somewhat, but i had to increase the deadzone to 5%. There still was some rattling while entering the pits but when i started driving it got normal. Then i realised what caused that. Karts have strong force for centering the steerning because of the wheel alignmets.
That force is apparently too much for our FFB output system, or to the hardware we own because we probably don't have a standalone FFB Deadzone in the center considering powers that center the wheel?
So imagine the next with strong centering, imaginatively and to clear this out to some people, theres a multiplyer value of 1.3.
A bumb with FFB value 1 makes your wheel turn to left over centerline. Centering forces come to play and multiply it with 1.3. That equals centering force of 1.3. That 1.3 thrusth your wheel over the center line to the right. The value of 1.3 ofcourse gets dampended a bit before the center line so it hits a peak of 1.1 on the right side. Multiply that with 1.3 and you get 1.43. That force throws wheel back to left, some dampening occours again and you get a peak value 1.3 to the left. The dampening increases when wheel starts to turn more and more.
See the pattern here?
Now what if we could have a seperate, user- adjustable damper/deadzone for this centering force, just close to the centerline of the steerning with next adjustable parametres:
-Precentage or degree value for deadzone while standing still
-Minimum Precentage or degree value for deadzone while driving and in witch speed does it occour.
-Linearity Adjustment for deadzone decreasement
I attached a picture to clarify what i'm speaking about since i have a feeling that i'm not as clear about this as possible.

Hopefully this helps and is an idea worth testing and possibly even implementing.
