How does it work
Predictive lap timing has been available for some time, but traditional methods have generally relied on a distance measurement (normally from a wheel speed sensor input) for calculation.
However, distances lap-to-lap almost always change: either by trying different lines, overtaking other cars, or perhaps by locking a wheel. Predicting a lap time accurately using this variable is nigh-on impossible, and is exacerbated on longer circuits.
Unrivalled Accuracy With Position Based Delta-T
We employ GPS position from a fast updating data logger - rather than distance - to align the reference and comparison laps. This means our lap time stays accurate, even if the driver takes a different line each lap. The system will maintain 0.1s precision the entire way around any circuits, including very long circuits such as the Nurburgring or Spa. Position based delta-T is far superior to distance on long tracks.
Display Modes
VBOX LapTimer has different display modes which can be accessed using the UP and DOWN buttons on the front panel. The data on each screen is calculated at all times, even if it is not displayed.

Predictive Lap Timing

The Predictive Lap Timing display (Delta Time) gives you an invaluable insight into how your current lap time compares with your fastest lap time. In addition, the high brightness colour LEDs give an indication of your SPEED relative to your FASTEST LAP.
This video shows how comparing speeds at the same points on the track compared to previous laps (Delta Velocity) can help accelerate the learning process.

Powerful Analysis Software
Circuit Tools is designed by racing drivers for racing drivers, with none of the complexity normally associated with data analysis software.
The software will automate many tasks and give you all the information required to improve lap times.

Fastest Lap First
The fastest lap from your latest session is automatically chosen and displayed on the graph window.
You can compare runs from your latest session, or from different days, drivers or sessions simply by importing them and clicking on the relevant lap time shown in the session window.
