VBOX analysis

VBOX data analysis, free in your browser

The .vbo format of Racelogic is recorded by the VBOX loggers and exported by many lap timers and apps (RaceBox, RaceChrono, Harry's LapTimer...). LapViz Studio opens it in the browser, on Windows, macOS, Linux or a Chromebook, and the 3D replay brings it back to life on the satellite view of the circuit.

Open a file in Studio Replay it in 3D

Lap comparison software: telemetry, delta time and racing line on the map

3D replay on the satellite view, with the ghost of the best lap

What LapViz reads in a VBO file

The text format of Racelogic, read on your computer.

GPS position, speed, heading and altitude
The other channels of the file, with their names: accelerations, revs, OBD or analog inputs when they were recorded
Date and device of the session, from the header of the file

Laps on the known circuits

LapViz does not read the lap timing settings of the file: it calculates the laps from the GPS track, on the circuits it knows.

Laps and sectors calculated on the circuits known by LapViz
The same timing for every logger, comparable on the leaderboards
A missing circuit can be submitted from the circuits page

Analyse and compare

Frequently asked questions

Is there free software to analyse VBOX data?

Yes. LapViz Studio opens the .vbo files in the browser for free, on Windows, macOS, Linux and ChromeOS: lap overlay, delta, channels, G-G diagram and 3D replay. Keep the Racelogic software to configure your VBOX.

Why are there no laps in my session?

LapViz calculates the laps of a VBO file from the GPS track, on the circuits it knows. Elsewhere, the session opens without laps: submit the circuit from the circuits page.

Which channels are read?

The GPS position, speed, heading and altitude, and every other column of the file, with its name.

Which apps export VBO?

Among others RaceBox, RaceChrono and Harry's LapTimer. When an app offers VBO and GPX, choose VBO: it keeps more channels.

Is it free?

Yes. The Studio and the 3D replay are free and work without an account; the LapViz account is free too.
