PS4 controller (throttle is always full :( no matter how much you press)

Summarize your bug Using a PlayStation 4 controller on pc. When I accelerate, it does it like on keyboard where you get full throttle no matter how much you press the trigger. Also I cannot find a way to open the map on ps4 controller so have to press m on keyboard when I want to access it. I understand ps4 controller isn't supported 'yet'?
