Setup Traction

Adjust traction control from the cockpit: toggle TC on or off, and step the four independent TC slot levels.

The View TC1 / TC2 / TC3 / TC4 entries turn the key into a continuously updating display of the slot’s current value. With dual-press enabled (default) the same key also adjusts that slot: a short press fires one direction and a long press fires the opposite — so one key replaces the separate Increase / Decrease keys you’d otherwise need.

Slot 1 is the canonical dcTractionControl field iRacing exposes for every TC-equipped car. Slots 2–4 are populated on cars that have multiple TC presets; cars that only have a single TC value render ”---” for the higher slots.

Each View sub-mode exposes a single extra setting in the Property Inspector:

  • Enable dual-press (default on) — when off, the key stays a pure read-only display and presses do nothing. When on, presses dispatch to the matching adjustment binding (e.g. View TC1 dispatches to TC Slot 1 + / TC Slot 1 −), so configure those bindings in the Global Settings → Setup Traction section.

The tap direction is a single plugin-wide setting under Global Common Settings → Dual-Press → Directions (default Tap increases, long-press decreases; the long-press always fires the opposite of the tap). The threshold separating “short” from “long” is a sibling setting Long-press threshold (ms) (200–2000 ms, default 500 ms). Both take effect on the next press without needing a restart.

Select the mode from the Setting dropdown in the Property Inspector. TC1–TC4 modes expose a Direction setting for Increase / Decrease; TC Toggle does not.
