It is recommended to check the website periodically for updates. To upgrade the FIM03 firmware, download the following from the VBOX automotive website.


  1. The FIM03 latest firmware file (.RUF extension file)
  2. Racelogic Upgrader software


Connect the RS232 (port 3) of the FIM03 to the PC via the RLCAB001 serial cable and apply power to the FIM03.

Double click on the .RUF upgrade file, which auto runs the Upgrader Software. Ensure the correct COM port is selected in Racelogic Upgrader, then click ‘Upgrade’ to start the procedure.

When this is complete, powering the FIM03 off and back on will complete the process.


Note: To confirm which COM port is assigned to the FIM03, check device manager.

Ensure that other software which may try and use the COM port communications, such as VBOX Tools, is closed.
