The profile works for PurrPRO FORMULA PEDALS and PurrPRO GT PEDALS.
- Download the official profile from fatblackcat.io/downloads (optimised for iRacing, ACC, Le Mans Ultimate), unzip it.
- In SimHub, import it in the ShakeIt Bass Shakers tab (not ShakeIt Motors).
- Go to Sound Output and assign PurrForce HC BRK (brake) and PurrForce HC T/C (throttle/clutch).
- Tune per-effect frequency and intensity in the effects profile — ABS, brake threshold, traction loss, engine RPM. Add your own effects freely.
Licensed SimHub requiredThe free version of SimHub adds a lot of delay to the effects, so they will not feel right while driving. Always use the licensed version.
No SimHub?iRacing users can drive the haptics through iRacing’s LFE output instead — but iRacing supports only ONE device at a time, so only one pedal gets effects. SimHub is the recommended path.
Haptics dropped out? If PurrForce goes quiet — often after a Windows update — open Sound Output in SimHub, click change target sound output and re-select the device. Windows sometimes reshuffles USB port IDs, so SimHub loses track of the haptics motor and just needs re-pointing. It is not a hardware fault.
