    It's coding addiction in general. That's what 20+ years of game development in my earlier days did to me :)

    Its better Karsten, its actually better :D:D:D, the only thing I changed was the scrub to 1.8, other than that super happy mate. Awesome work, I'm in two minds now, I wanna ask you to please stop ooorrr maybe there's something else that can be extracted from it still:p. Great job mate!

    How can i adjust only the force from lateral / caster, please?
    Is that scrub?

    You mean the new effect center momentum, maybe?
    Then adjust center_momentum downwards. 0.0 will remove the effect completely.

    I'm not 100% sure otherwise?

    Changes till now,
    Road Detail from 1.0 to 0.0, but not realy something happen.
    friction from 0.1 to 0.0, i don't like friction, because it eat's details from physics.
    center_momentum to 1.7 feels like friction and damping, but i cant' tell how.
    It's better for me off. 0.0, too.

    In SimuCUBE its nice to use only Recon at 3 -5.

    Update:

    * "Center Momentum" auto amplitude fitting.
    * "Center Momentum" smart blending to only fill in what is missing.

    Feels more natural & avoids too much force added on turning, specially at low speeds.

    It's still "silver bullet", but a more mature and gentler v2.

    It's a consistent update Karsten, I noticed you removed some of the parameters and lowered others, it got me worried, but it's definitely really good.

    The loss of grip around corners is quite cool, I'm using Curitiba to test your FFB cos of the heavy braking at the end of the straight and slow corners after, and for the fast long curve leading to the main straight.

    Had for the first time ever the experience of understeering off track quite bad with the sprintcar, not a criticism more of an observation. I also feel that it is a tiny bit lighter than usual the "overall feel" which I could fix with more Gain I guess, but since you not quite done yet I will leave it for now. Also, every car feels different as well in terms of "bodyweight" and with very good road and kerb detail.

    Solid update again mate, going in the right direction for me.

    Update:

    * FFB signal improvement. Custom made FFB scaling function replaces Sigmoid function.

    The Sigmoid function had the issue that it compressed weak forces, a kind of anti-LFB effect.
    The custom made function is a better fit. No compression at the low end & only at the very far top does it compress. It also maintains almost perfect 1:1 ratio all the way up until "compression zone".

    I'm actually considering removing the wheel base type stuff again as it seems the values are so similar anyways...
    But the latest file requires a little value adjustment loving, since the use of the Sigmoid function earlier had the effect that we adjusted to fit that. If you make it optimal I will push that in there :)

    Oh and the file does loosen up the LFB, maybe that is what you feel.
    You can adjust the variable "rack_lfb_blend" which is set to 0.7 upwards. Maybe it does need to be 1.0. I'm not sure since my DD wheel does not really need it in the first place...

    Can't make it work for me, the overall feeling now is lighter without any variation of speed or breaking, I feel a little bit on elevation change, but whether coming out of the pits or driving fast down the straight the car feels the same.

    I tried changing the settings as you said and no noticeable difference tbh, if I crank up LFB in-game close to 100 it gets better, but no variation. On the previuos silver bullet If add gain and lfb I get that pitch and yaw quite good and the overall weight of the car as well, with some noticeable variation in changes of elevation and somewhat under breaking too.

    I tried switching it to CSW 1.0, but it didn't change much if anything, tried changing some other values but equally unnoticeable. It feels very much like a pendulum now from when you leave the pits to driving fast.

    I compared it to the last Silver Bullet v2 and with a few changes to Gain and LFB I can easily mitigate most of this feeling.

    I find this pretty weak. I had to increase to 100/80/50 from Nuscorpii's latest from 80/50/50 to get close FFB. Just checking as you might have decreased some values.... though I'm guessing not too, as it's quite a jump.

    Good suggestion too to remove the wheelbase type, as previously there were a few times I've forgotten to activate the T300 in file :D

    ...Ninja'ed by F.Santos ;)
