This is a small tool that maps the Richard Burns Rally (NGP) RPM data to the Logitech G27 and G29 LED bars. It's heavily based on Andris0's DR2G27. Also thanks to mika-n for some hints on how to get the RPM limits per car directly from the game files.
Activate UDP telemetry in the RSF launcher and set IP and port to: 127.0.01:6776
By default 127.0.01:6776 is used to listen for telemetry. Using the -i --ip and -p --port parameters, a custom adress can be defined. For example:
.\rbr2g29.exe -i 192.168.0.20 -p 1234
