How do you make the car turn tighter.

I have the logitech 920 wheel.

My maximum wheel rotation setting is set at 360 degrees.

However when making a slow tight turn, i have to rotate the wheel more than 3/4 from the position I started from.

(in other words, when making a left turn, if my right hand is at the three o'clock position, I have to turn counter clockwise to about the six o;clock postion)

I want to make the rotation of the wheel rotate less, but get a tighter turning ratio.  (have my left hand go from the three o'clock position to the 10 o'clock position to make a tight turn.
