irFFB can feed the 360 Hz steering column torque data recently made available in iRacing telemetry to your wheel, upsample and apply low-latency digital filters to the standard (60 Hz) iRacing FFB output and modify the feedback via a number of effects based on live telemetry.
It can also drive a 'Jetseat' and fans if you have them.
There's more detail in the wiki..
Please Note I no longer use this myself and as you can see I haven't updated it since 2022. I've archived the repo. You may be interested in checking out Marvin's Awesome iRacing App which is what I've been using recently. Else, iRacing FFB has improved a lot since irFFB was a thing.....
