You set FFB with several sliders, not one. And official manufacturer recipes for ACC exist almost nowhere — we know of exactly one exception. We separate what is reliable from pure matter of taste.
Force feedback in ACC is set through several sliders, not through a single filter. And honestly: there is no official manufacturer recipe for ACC — every table of values online is community taste. So we separate visibly what is reliable (what a slider does, the clipping method) from pure preference.
Five things hold across all brands: set the force by the clipping indicator; keep Min Force small on gear and belt wheels (~5–12 %), 0 on direct drive; turn the software centering spring off; match the steering lock to the in-game value; set the in-game damper to 0 and the frequency to 400 Hz. For Moza, Fanatec, Logitech, Thrustmaster and Simagic there is one deep slider overview each, with confidence.
No. No manufacturer publishes an official ACC FFB recipe — Moza support even says ACC needs no special config. Every table of numbers is community taste; only the slider functions and the clipping method are reliable.
On direct drive bases (Moza, Fanatec DD, Simagic, T818) 0 — otherwise the center twitches on the straights. Gear and belt wheels like the Logitech G29/G923 or Thrustmaster T300 need roughly 5–12 % to overcome the dead center.
By the clipping indicator in the game: turn the gain up until the bar just stops hitting the top under full load, then come back about 5 %. Stronger bases need a lower gain.
That is thermal fade — belt wheels like the T300/TX/T248 reduce the FFB when they get hot. The remedy: keep Overall Strength moderate (75–80 %, not maximum) and ventilate the base. The direct drive models (T598/T818) do not have this.
