Steering wheel settings (logitech g29)

Hello,
recently i bought Logitech G29 steering wheel and i got serious problem with setting it up…
On default settings i get “fishtail” effect everytime i make a turn on higher speeds. It doesnt occurs when im using keyboard. Right now i cant make any races on my steering wheel cuz im getting caught from one slip to another…
So please, if someone got any tips for me or if u can post your settings that works for you please post it.
