Hi Amy, if you want to have 900 degrees turning and/or use the stick sifter on the right of the steering wheel, you need Logitech Profiler and Logitech Gaming Software, after you download both of the software's and install them, go to the Logitech Profiler and click on the Device tab and then the Game Controllers tab, after that click on properties and then on settings, then at the Degrees of Rotation slide the bar all the way to the right (900 Degrees) and check the box at the bottom called Allow Game To Adjust Settings (if you also want force feedback tick the rest of the boxes, however the force feedback will not work unless you tick the force feedback box in the controller section of the settings tab in game) to use the stick shifter, simply go to the game settings, click on the keyboard tab and change the shift up and shift down tab from whatever it sais to gear shifter up and gear shifter down (could be written differently in game).
