Performance Box Touch Firmware - Release Notes

Compatible Products:
PBT-V1 (10 Hz)
PBT-V2 (25 Hz)

Version - 16 June 2023


  • Adds Support for latest hardware

Version - 18 October 2022

Includes all features of version (V2 only release) plus the following:


  • Addition of miles/kilometres option for distance on Average Speed screen.
    Users can now change between metres/kilometres, or feet/miles for distance display on the Average Speed screen, previously only metres or feet were available.


  • [Fix] Lateral and Longitudinal acceleration channels now zero below 4 satellites.
    Lateral and Longitudinal Acceleration channels were previously displaying values when the satellite count was 3, when anything below 4 should give no data for all GNSS channels.

  • [Fix] Decel test speed setting was not always updated to reflect a unit change.
    Changing speed units could result in the decel test using the previous speed value [but displaying new units) until a power cycle.

  • [Fix] Issue on average speed screen when crossing midnight UTC.
    When crossing midnight UTC, the elapsed distance could reset to zero and the average speed would change to show live speed.

  • [Fix] Issue with the unit displaying an error on bootup due to corrupted lap timing settings.
    Any track name of the maximum size would cause an exception when saving to EEPROM.
