This page contains an introduction and overview of the Racelogic Performance Box Touch product and what you need to know before you start using it.

It measures speed, lap and split times, delta-T, acceleration, deceleration, distance, and more.

All these parameters are logged to an SD card and can be viewed live on the screen and analysed in detail later using the VBOX Test Suite or Circuit Tools software products.

Performance Box Touch is supplied ready to use with the default Performance App installed. This app provides the core functionality of the unit, including logging, display modes, and test features described in this user guide.

It is possible to install different apps on the Performance Box Touch unit to support different testing requirements. If a different app is installed, the behaviour, including available features and CAN output, may change.

The functionality described in this user guide applies to the default Performance App. App-specific functionality for other Performance Box Touch Apps is documented in the Performance Box Touch Apps section.

To restore the default Performance App, reinstall the latest Performance Box Touch firmware.


The unit includes an internal antenna, which may be sufficient in open environments. However, for reliable and repeatable results, especially when used inside a vehicle, the external antenna is recommended.

Connect the GNSS antenna to the unit and place it with a clear view of the sky. Avoid placing the antenna under metal surfaces, as this can significantly reduce signal quality.

You can find more information about best practices in the GNSS Antenna Placement article.


Performance Box Touch records all data to an SD card inserted into the side of the unit. If the unit cannot detect an SD card, logging will not be available.

It comes supplied with an 8 GB SDHC card in a FAT32 file format, which is the only file format supported.

If you are looking to purchase a new SD card, we recommend that any card used has a write speed of more than 7 MB/s (4 MB/s is the absolute minimum) and a speed class of 10 (4 is the absolute minimum). Use SD cards from quality brands such as Transcend, SanDisk, Kingston or Lexar for the best results.

SDHC cards (2 GB to 32 GB)

Supplied or purchased SDHC cards are formatted in the FAT32 file format. This format is supported by Performance Box Touch.

SDXC cards (64 GB and above)

Purchased SDXC cards will be formatted in exFAT or NTFS file formats; these formats are not supported by Performance Box Touch (please reformat as per instructions below).

FAT32 reformatting for media with sizes up to 32 GB can be done directly within Windows by right-clicking on the media and selecting 'Format'.

If you would like to format media with sizes above 32 GB into a FAT32 file system, this cannot be done directly in Windows, as it is not the standard formatting for the file. However, many third-party software programs can be used to reformat media to allow them to work correctly with our products. We can recommend This Tool as a free option from the SD card organisation.


Performance Box Touch is powered via the test vehicle (12 V vehicle power) using the supplied power cable (RLACS184).

The unit will automatically turn on when connected to power.

While the unit is starting, it will display the following splash screen:

On start-up, the unit:

  • Searches for satellites.
  • Detects the SD card.
  • Prepares for logging.

Mode Selection

The very first time the unit is started, it will present the Select Mode screen where you can select the required Display Mode. After this, it will automatically display the last used display mode on power-up.


The unit supports multiple display modes, each designed for a specific type of test, such as speed, acceleration, deceleration, or lap timing.

Refer to the Display Modes section under User Interface for more information.


Before using the unit, make sure that:

  • A compatible SD card is inserted.
  • The unit has a clear view of the sky or is connected to an external GNSS antenna that has been installed according to best practice.
  • The unit is powered from a suitable vehicle supply.
