Lap Timing Mode Overview
There are 2 Lap Timing display screens:
Lap Timing Mode - Primary Screen
This is the default lap timing screen and it displays live lap timing information in relation to:
- A set Start/Finish line
- Separate Start and Finish lines
- A Standing Start line and separate Finish line
- A reference Lap
You can reset the data on the Primary Lap Timing screen by tapping the Reset button at the bottom of the screen, or by long-pressing on the screen.
The screen is split into two sections:
Left-Hand Side
- Lap time: This will show either a live rolling lap time or a static lap time (previous lap), depending on the Rolling Lap Time setting. If you want a rolling lap time displayed, the previous lap time will be displayed for 5 seconds when a new lap starts, before reverting back to displaying the current live lap time. If the Start/Finish line has yet to be crossed, the circuit name/layout will be displayed with a distance countdown to the Start/Finish line (if the unit has satellite lock). If you have enabled Standing Start, you will see a 'Standing Start Mode Enabled' message. If you have not defined a Start/Finish line or VBOX Touch cannot detect a Start/Finish line, you will see a 'No start line' warning.
- Time difference to best lap: This is the time difference between the last completed lap time and the quickest lap time. The data displayed is configured in the Rolling Lap Time settings. If Rolling Lap Time is disabled, the data will be displayed continuously. If Rolling Lap Time is enabled, the data will appear for 5 seconds after a lap has been completed. If the Start/Finish line has yet to be crossed or a lap hasn't been completed, it will not be displayed.
- Reference lap time: This is the current active reference lap time and it will update when the reference lap is superseded by a faster lap time, unless you have set fixed the Reference Lap in the Settings. If you have fixed a reference lap, you will see a padlock icon to the right of the reference lap heading. If a reference lap time is being created, you will see a rolling lap time.
Right-Hand Side:
- Delta-T: This presents a live difference in lap time at the current location on the track, between the current lap time and the reference lap. If the detected speed drops below 10 km/h or the satellite reception is lost (less than 4 satellites), the time comparison will freeze on the last known valid value until the speed is increased or the satellite reception is regained. If a reference lap is being created, you will see a 'Creating a Reference Lap' message.
- If the current lap is faster than the reference lap, the value will be signed negative and be green in colour.
- If the current lap is slower than the reference lap, the value will be signed positive and be red in colour.
- If the current lap is the same as the reference lap, the value will be unsigned and be black in colour.
- Session time: Total time passed within the session.
- Completed lap count: Number of completed laps within the session.
OR
- Delta-V: When there is a reference lap, the 4 LEDs at the top of the screen will provide a live reference lap speed comparison at the current location on the track. You can configure this in the Delta-V Range settings.
- If the current lap is faster than the reference lap, the LEDs will be illuminated in green.
- If the current lap is slower than the reference lap, the LEDs will be illuminated in red.
- If the current lap is the same speed as the reference lap, the LEDs will be off.
IMPORTANT
Lap timing gates are bi-directional and will be triggered when passing through in either direction.
Lap Timing Mode - Secondary Screen
This lap timing screen displays a lap time in relation to:
- A set Start/Finish Line
- Separate Start and Finish Lines
- A Standing Start line and separate Finish Line
- A reference Lap
Lap Time
This will show either a live rolling lap time or a static lap time (for the previous lap), depending on the Rolling Lap Time settings.
If a rolling lap time is being displayed, the previous lap time will be displayed for 5 seconds when a new lap starts, before it reverts back to displaying the current live lap time.
If the Start/Finish line has yet to be crossed, the circuit name/layout will be displayed with a distance countdown to the Start/Finish line (if the unit has satellite lock).
If you have enabled Standing Start, you will see a 'Standing Start Mode Enabled' message.
If you have not defined a Start/Finish line or VBOX Touch cannot detect one, you will see a 'No start line' warning.
Time Difference to Best Lap
This is the time difference between the last completed lap time and the quickest lap time, and it is displayed depending on the Rolling Lap Time settings.
It will either display continuously if you have set the Lap Timing screen to display a static lap time, or will appear for 5 seconds after a lap has been completed if you have set it to display a rolling lap time.
If the Start/Finish line has yet to be crossed or a lap hasn't been completed, this data will not be shown.
Lap History
View a history of the lap results by selecting the Results button at the bottom of the screen.
The Lap results will remain in the history until you press the Reset button.
The most recently completed lap will show at the top of the screen and the fastest lap will be highlighted. Use the scroll bar on the right-hand side of the screen to scroll through the history.
Included information:
- Lap number

Speed Display Mode Overview
Speed Display Mode - Speed Screen
This is the default speed screen and it displays live speed data.
If you have selected a Target Speed in the Speed Settings, it will be displayed in grey underneath the live speed.
NOTE
If the vehicle is travelling slower than 0.5 km/h or if Performance Box Touch has lost its satellite lock (fewer than 4 satellites), the speed value will be shown as 000.0.
Speed Display Mode - VMAX Screen
This screen displays the absolute top speed reached until you tap the Reset button in the screen footer.
If you have set a Target Speed in the Speed Settings, it will be displayed in grey underneath the VMAX value.
Speed Display Mode - Average/Distance Screen
This screen is split into two sections:
Left-Hand Side
The average speed, displayed using either continuous or moving calculations.
Right-Hand Side
The distance travelled (since the last boot-up or power cycle).
The two data sets are displayed on the same screen when Performance Box Touch detects movement.
Reset the screen at any time by tapping the Reset button at the bottom of the screen.
If you have set a Target Speed in the Speed Settings, it will be displayed in grey underneath the average speed.
Performance Box Touch has 4 LEDs at the top of the unit, just above the screen. These LEDs provide visual status and/or test feedback.
Some behaviours will indicate different things depending on the mode/function the unit is performing.
If Alert at End is enabled, the LEDs will flash green for 0.5 s once the test end criteria are met.
If Alert at End is enabled, the LEDs will flash green for 0.5 s once the test end criteria are met.
In Lap Timing Mode, the LEDs provide an indication of the speed compared to the Reference Lap speed (Delta-V).
You can adjust the Delta-V Range in the Lap Timing Settings to change the LED behaviour in relation to the Delta-V speed.
There are 3 options:
- 2 km/h (1.2 mph)
- 5 km/h (3.1 mph) - default
- 10 km/h (6.2 mph)
These relate to the maximum speed difference at which the LEDs are brightest.
When the current lap is quicker than the reference lap by > than the set Delta-V Range, all 4 LEDs will be illuminated in green.
For example, when Delta-V Range = 5 km/h:
