Rewired can handle throttles on recognized controllers in two ways: 1. Throttles return a value of 0 when fully disengaged and +1 when fully engaged. 2. Throttles can be set to return values from -1 to +1 if the option is set. See Throttle Calibration Mode. To detemine what's happening with your throttle, look at the live value being returned by Rewired for the Action that is mapped to it using Debug Information. If it's returning a 0 - 1 value and the game code is expecting a -1 to 1 value, change the Throttle Calibration Mode setting.
