Logging

Updated on Mar 4, 2026

The VBOX Sport can record to the MMC, SD, SDHC and SDXC media cards that are formatted in a FAT or FAT32 format.
 

Note: SDXC cards will be formatted as exFAT by default, a format type not supported by the VBOX Sport.  They can still be used, as long as they have been reformatted to FAT32.  Various free third-party applications are available online to format SDXC cards.

VBOX Sport (v3) logs 25 Hz GNSS data in a .VBO file format to an inserted SD card at a rate of around 8.7 MB per hour. There is an option to enable logging of .VBO files direct to an iOS device via the Racelogic Laptimer application. This option to enable this can be found in the 'Settings' area of the application. When this setting is enabled .VBO data files will be saved within application documents and can be accessed via iTunes.

Logged files can be opened in Performance Tools or VBOX Test Suite for straight-line analysis, or Circuit Tools for circuit/lap timing analysis.

The default logging behaviour of the VBOX Sport is to automatically start and stop logging. The unit starts logging when it has achieved satellite lock and it has detected a speed value that is higher than 0.8 km/h. It will stop logging when it detects a speed below 0.8 km/h.

By using this automatic logging you can ensure that VBOX Sport captures all data while the vehicle is moving. 

VBOX Sport has a quick-press 'manual override' option that gives you the ability to start and stop logging via the front panel logging button.

When you press the logging button, VBOX Sport will start logging immediately, and will not stop logging until you press the record button again (regardless of speed or GNSS lock).  

Note: As soon as VBOX Sport has stopped logging and it is detecting a speed of 0 km/h, it will automatically switch back to the default automatic logging behaviour to avoid data loss. 

Racelogic Performance Test and Laptimer iOS applications are compatible with any IPhone, IPad or IPod touch running iOS 7 or above. Devices that do not support this version of OS are not compatible.

Note: This device does not currently support Android.
