TrackTune Dashboards and Widgets

Build a custom dashboard with TrackTune widgets and readings. Use the Meters builder reference for layout, styling, alarms, previews, and Checks.

TrackTune widgets need TrackTune on the car

The shift bar, G-force plot, grip rail, corner cards, map, lap timer, launch timer, and drive recorder are TrackTune widgets. So is any widget that shows a TrackTune reading: the session peaks and session time, combined G, the smoothed G readings, and the grip, corner, lap, and launch readings. TrackTune comes with every ScreenTune license at no extra charge. Every other widget and reading in the builder, alarms included, is part of Meters.

The builder offers TrackTune widgets, templates, and readings to every license, with no badge, lock, or upgrade banner. A design with them saves and goes to the car like any other.

The car draws them only when it runs ScreenTune 1.2.0 or later. On a car still running an older ScreenTune package without TrackTune, the spaces those widgets take stay empty while the rest of the dashboard works. Update the car to ScreenTune 1.2.0 or later to show them.

On the car, these widgets read a session the head unit keeps itself, so the peaks, corners, laps, launch times, and the track survive a switch to CarPlay or Android Auto and back. Switching the car off for 5 s or more starts a new session and clears them.

Shift bar (TrackTune)

A segmented bar on engine speed. It fills with the revs, and at the shift point the whole bar flashes or lights up. It’s one of the ways to show an engine-speed reading, so Show as on a tachometer bar switches to it.

On Look:

Scale: Direction, Minimum and Maximum, and Engine. Engine has two presets, ND2 · 7,500 and ND1 · 6,800, that set the range, the colors, and the shift point for that redline. Editing any of them away from the preset clears it.
Shift point: At the shift point is Flash (the whole bar flashes in the Shift color twice a second), Light up (the whole bar turns the Shift color), or Nothing. Shift at sets the rpm.
Segments: 4 to 40 segments, the Gap between them, and Fade the low segments.

On Colors: Fill, Unlit, and Shift. Color by value colors the lit segments, as on a bar.

The default is the ND2’s: 0–7,500 rpm, shift at 7,200. For a tuned car, set the maximum and Shift at to its limiter.

G-force plot (TrackTune)

Plots the car’s side-to-side and front-to-back acceleration, with the yaw rate turning the car marker. The marker moves the way you’re pushed: up under braking, right in a left turn. It reads its own data, so Reading has only Update speed. It draws in the square of its shorter side, and a plot can be at most the screen, 800 × 480, so its rings are at most 480 px across.

On Look:

Scale: Outer ring is Auto, or fixed at 1, 1.5, 2, or 2.5 g. Auto starts at 1.0 g and steps to 1.5, 2.0, and 2.5 g as the hardest moment of the drive passes 0.8, 1.3, and 1.8 g. With a fixed ring, readings past it stop at its edge.
Smoothing: Off (the marker jumps to each reading, ten times a second), Normal (glides between readings and ignores one-off spikes), or Smooth (glides a little behind the car; steadier on bumpy roads).
Marker: Car, with Turn with yaw, or Dot. The dot takes the braking, coasting, or accelerating color.
Trail: 0 to 8 Dots and a Length of 0.5 to 5 s. Each dot shows where the marker was a moment ago and adds 3 screen elements to the car budget.
Labels: Brake, accel, left, right at the edges, and Ring values.

On Colors: Trail, Rings, and Labels, plus Braking, Coasting, and Accelerating with the dot marker.

Lateral G is computed from yaw rate and speed. See G-force accuracy for the factory sensors and their limits. The plain G-meter is part of Meters.

Grip rail (TrackTune)

How much of this drive’s grip is in use: combined cornering and braking or accelerating force, against the most the car has pulled since Meters started. The bar grows from the middle.

Purple is cornering, orange is wheelspin, and the inner bar is the throttle (green) or brake (red) share.
Past the last best, the ends turn blue.
While coasting, it shows the revs in white.

On Look, under Rail: Direction (Vertical or Horizontal), Show new best, which paints the part past the last best in its own color, and Narrow throttle/brake bar, which leaves the cornering or wheelspin color showing beside the inner bar.

On Colors: Cornering, Throttle, Brake, Wheelspin, New best, Coasting, and Track.

The rail’s reference is the drive’s own best, so it starts small and settles after a few hard corners. Its readings, Grip Used (%) and Wheelspin, can also drive number and indicator widgets.

Corner cards (TrackTune)

The last corners you drove, newest first: each one’s lowest speed, lowest RPM, and peak cornering load. A card posts when the corner ends. RPM shows -- when it dropped out mid-corner.

Cards: 1 to 5 Cards, Layout Column or Row, and the Gap.
Show: Min speed, Min RPM, Peak load, Exit speed, Exit vs best lap, Labels, Units, Last / Prev tags, Left / right badge, and NEW badge.
Card plates: Opacity, Radius, and Outline.
Colors: Values, Labels, Badges, Faster exit, Slower exit, and Cards.

Exit speed is your speed where the corner ended. Exit vs best lap compares it with your best lap’s speed at the same point, faster in green, and shows -- until the lap timer has a best lap. Both are off by default. Corner exit vs best in Add is a column of cards with lowest speed, exit speed, and exit vs best lap. Corner strip is four cards in a row.

Peak load is the road-estimated lateral acceleration, shown in g. Corner Count, In a Corner, New Corner, and the last corner’s figures (Last Corner Minimum Speed, Last Corner Minimum RPM, Last Corner Peak Load, Last Corner Exit Speed, Last Corner Exit vs Best Lap) are also readings for other widgets.

Maps, timing, and recording

Maps and GPS traces show a fixed course picture or the drive’s trace.
Lap timing compares laps and sectors with your best.
Launch timing measures speed and distance targets.
Drive recording shows USB recorder status and adds Commander controls.

Session peaks and TrackTune readings

These readings have no widget of their own. Show them with a number, bar, alarm, or other widget, and that widget becomes a TrackTune widget.

Reading	What it is
Peak Lateral G, Peak Left G, Peak Right G	The hardest cornering this session, overall and per side
Peak Braking G, Peak Acceleration G	The hardest braking and acceleration this session
Max RPM	The highest engine speed this session
Session Time	How long the session has run, kept when you switch apps
Combined G, Peak Combined G	Lateral and longitudinal G together, now and the session’s highest
Lateral G, Smoothed, Longitudinal G, Smoothed, Lateral G, Steady, Longitudinal G, Steady	The displayed G after smoothing, as the G-force plot and grip rail use it
Grip Used, Wheelspin	The grip rail’s readings
Corner, lap, and launch readings	Under corner cards, lap timing, and launch timing

Peaks come from the displayed G, which is limited to ±3 g on each axis. They clear when a new session starts. Peak cornering G and Peak braking G in Add are ready-made number widgets on two of them.

The raw Lat G and Long G readings are part of Meters. Only the smoothed and combined versions above are TrackTune.
