iRacing Telemetry

It is possible to delete old iRacing files to prevent the iRacing telemetry folder using a large amount of storage from data logging. When enabled, any files within the C:\Users\Username\Documents\iRacing\telemetry folder that are more than 7 days old will deleted.

When iRacing is detected, the 'Use iRacing telemetry' checkbox will be automatically ticked, meaning that after the session, the .vbo data file is edited to correct the position received from the game to the real world location. This ensures that the correct racing positioning information is obtained.
