I'm currently having the same problems as Harry, i have configured project cars 2 like you said and i have disabled the revlights options in pcars2.
But when i'm configuring fanaled and when i test the devices with fanaled without the game there is no problem. But as soon as i start the game the led don't work anymore. It feels like even if you disable the revlights options in project cars 2, the game take the control of the led on the wheel.
Does anybody tried and succeed to use the rev lights with fanaleds and project cars 2, if so is there some additional step that i am missing ?
Thanks in advance.
