The game requires 4 analogs.
1 is mapped to the Gas
1 is mapped to the brake
1 is mapped to the steering
1 is mapped to the Forward/Rev switch, with the machine having an physical locking position on the handle so it will output the "Max" commad when locked in F, and be "Zero" when locked in R,
The F/R is the part that I could not map "properly" thus why it is always in F.
