Drag Race Timing
Functions → Drag Race Timing
Drag Race Timing measures elapsed time and speed from a standing start, recording results at standard drag strip distance markers. Distance is calculated by integrating the configured speed channel.
Enabling
Check Enable to activate the function.
Configuration
| Setting | Description |
|---|---|
| Speed Channel | Source speed in km/h — required for distance integration |
| Arm Conditions | Conditions that must become true before a run can start |
| Start Conditions | Conditions that trigger the run start on a rising edge |
| Abort Threshold | Run is aborted if speed drops below this value (km/h) |
Typical Setup
- Arm when the vehicle is staged (for example, a staging light input or speed below 2 km/h).
- Start when the vehicle begins moving (for example, speed exceeds 2 km/h, or a launch event fires).
Distance Markers
When a run is active, the function records time and speed at each marker:
| Marker | Distance |
|---|---|
| 0–60 ft | Start line |
| 60 ft | 18.3 m |
| 330 ft | 100.6 m |
| 1/8 Mile (660 ft) | 201.2 m |
| 1000 ft | 304.8 m |
| 1/4 Mile (1320 ft) | 402.3 m |
The run completes automatically when the 1/4 mile distance is reached, or aborts if speed falls below the abort threshold.
Output Channels
The function writes elapsed time and trap speed at each marker, plus cumulative Drag Time and Drag Distance channels during a run. A live drag time slip preview is shown on the configuration page when a device is connected.
Displaying Results
Map the drag timing output channels to Value or Time gauges on a screen. For example, show 1/4 Mile Time and 1/4 Mile Speed on a dedicated drag page.
Drag timing can also work alongside Lap Timing — use a finish beacon on a drag strip start/finish line for point-to-point events.
