What do the Advanced Settings mean?
Advanced Settings are for power users. They are similar to those found on many physical controllers.
Steering Trim: Think of this as aligning the wheels. It will adjust steering to the left or right so that the car drives in a straight line when the wheel is centered.
Steering EPA: This will limit the turn radius of the car so that it can only be turned left or right to a certain point. The default of "100" doesn't limit the turn radius at all.
Throttle Response Curve: This sets the responsiveness of the on-screen throttle slider. The bottom of the graph (x-axis) is how far up the on-screen slider is, and the left side (y-axis) is how fast the app is telling the car to go.
Steering Response Curve: Like throttle, this sets the responsiveness of the on-screen steering controls. The bottom of the graph (x-axis) is how far to the left or right the on-screen wheel is turned, and the left side (y-axis) is how far to the left or right the app is telling the car to turn.
