Setup Chassis

Adjust chassis setup options from the cockpit: differential curves, anti-roll bars, spring preloads, shock absorbers, and power steering. Placed on a Stream Deck+ dial, the same action becomes a chassis-setup dial with the live value on the touch strip — see On a dial below.

The View … entries turn the key into a continuously updating display of the current value in the car. With dual-press enabled (default) the same key also adjusts the value: 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.

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 Diff Preload dispatches to Diff Preload + / Diff Preload −), so configure those bindings in the Global Settings → Setup Chassis section. Weight Jacker Left / Right do not appear as adjustment modes in the Setting dropdown; their +/- bindings still live in Global Settings → Setup Chassis so the View can drive them via dual-press.

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. Adjust modes are directional — pick Increase or Decrease in the Direction setting to control what a button press does. View modes show a live readout and, with Enable dual-press on (default), also accept short / long presses — see View sub-modes above. They don’t use the per-action Direction setting; the tap direction is the plugin-wide Global Common Settings → Dual-Press → Directions.

Placed on a Stream Deck+ dial, Setup Chassis becomes a chassis-setup dial. Pick one component with the dial’s Component dropdown; turning the dial steps it up or down in the car, and the touch strip shows that value live as a big, color-coded number. It uses the same key bindings as the keypad modes, so no extra configuration is needed if you already use them. The Property Inspector automatically shows the dial settings below (instead of the keypad Component and Direction) when the instance sits on a dial. See Dials for how the shared dial gestures work.

  • Method: Key binding — the same Setup Chassis increase/decrease bindings the keypad modes use. Configure them in the Related Key Bindings section; the Property Inspector shows a status line indicating whether each is set.
  • Dial: Rotating adjusts the selected component (clockwise = increase, counter-clockwise = decrease). Both the increase and decrease key bindings must be set.
  • Telemetry-aware: Yes for the differential, anti-roll bars, and power steering — the touch strip shows the live value from telemetry (see the table below). Springs and shocks have no telemetry, so their strips show the label only.
  • Elgato Stream Deck+ — dial rotation and a touchscreen readout that always shows.

Dials are currently Stream Deck+ only — the action can’t be placed on Mirabox knobs or Ulanzi dials yet (see Dials).

The chassis component the dial controls. Each renders as a color-coded “dash box”: a short label on top and the live value as a large number. Each setting has a built-in accent color, but you can override the border, label, value, and background colors in the Dash Box Appearance section of the dial settings. Weight jackers and the View sub-modes aren’t offered as rotation settings.

Component Label Telemetry source Shown as
Differential Preload PRELD dcDiffPreload integer
Differential Entry D-IN dcDiffEntry integer
Differential Middle D-MID dcDiffMiddle integer
Differential Exit D-OUT dcDiffExit integer
Front ARB FARB dcAntiRollFront integer
Rear ARB RARB dcAntiRollRear integer
Left Spring LSPR (none) label only
Right Spring RSPR (none) label only
LF Shock LF (none) label only
RF Shock RF (none) label only
LR Shock LR (none) label only
RR Shock RR (none) label only
Power Steering PWR dcPowerSteering integer

When a telemetry-backed component has no data the box shows ---. Springs and shocks still rotate (they use their increase/decrease bindings); their strips just can’t show a live number.

Setup Chassis has no on/off toggle, so the dial press and touchscreen taps do nothing — the dial is rotation-only.

Adjustment modes with a live value (on Setup Chassis: Differential Preload, Differential Entry, Differential Middle, Differential Exit, Front ARB, Rear ARB, and Power Steering) can render as paired keys: place two keys with opposite directions next to each other (or three, with a View key in the middle) and both show the live value — no separate display key needed. Choose the look under Key Style:

  • Legacy (arrows) — the classic static arrow icon (default for existing keys).
  • Split — label on top, live value in the middle, a big +/− below (default for newly placed keys).
  • Edge chevrons, Joined pill — alternative value-showing pair looks.
  • Big +/−, Big chevrons, Pill end — no-value styles for the outer keys of a 3-key group; the View key in the middle shows the value (set its Display Style to Pill middle to span the pill across all three keys).

Values are shown without units for maximum size. Edge chevrons, Joined pill, Pill end, and Big chevrons take a Position in Pair setting (Auto follows the direction: increase right, decrease left; pick Top/Bottom for vertical stacks). Holding a paired key repeats the adjustment until released. Colors follow the normal color overrides (the +/− accent is the Graphic 1 slot); pill styles disable the normal border — the pill itself is the frame.

Springs and shocks have no live telemetry value, so they stay legacy-only — no Key Style control appears for them. Weight Jacker Left / Right exist only as View sub-modes here; their Display Style dropdown offers the pill-middle options like any other View.
