Logitech g27 (Euro Truck Simulator 2) is buggy

Good day! The control from the G27 logitek is buggy: when the controller is turned somewhere around 270 degrees, the steering wheel in the game sharply turns to the maximum. From zero to 270 no problem, the controller and wheels in the game are synchronized. I tried to turn the sensitivity down to a minimum, then this problem disappears, but there is a sickly delay between turning the real steering wheel and the wheels in the game. Is it possible to fix it somehow? Thanks in advance for your help!
