Hi,
I am testing this mod, but I must report my G27 gives me headaches, too: currently I am plagued by my G27 going amok when using this mod, it rattles and vibrates like crazy as if driving over extremely heavy clobberstone. I do not have this with any other car in AC, also not the Kunos Lotus Formula Car, the Tatuu, as well as mod formula cars like Williams-FW32 or McLaren MP4-13 - they all work fine.
I tried FFB minimum force halved from 12% to 6%, no difference. Maximum FFB force halved from 100% to 50%: no difference, halving the values for street, kerb ertc feedback: also no difference.
Its just and only this one car, no other: not the few mod cars, and not the Kunos default cars.
Any ideas? Please no suggestion to cut down to zero all FFB in general, this would effect all other cars as well, and that sounds like no good trade to me.
