Automobilista 2 Custom Force Feedback - Overview & Recommendations

There are ways to customize the FFB in RaceRoom. You can use an RCS file, although the major update may have introduced completely new codes or variables.
Alternatively, you can try Marvin's FFB app, which generates pure telemetry-based FFB and has nothing to do with RaceRoom's original FFB anymore.
Or you can adapt it using suitable hardware, as I do.
