The powertrain has a set of output requests which gives information about the states and
        the outputs of the powertrain with time. They can be accessed by the Request Subroutine
        POWERTRAIN_REQ with the parameter value of 1, 2, or 3.

                Modulated Throttle | 
                The throttle that is applied to the engine after the modulation from the
                  anti-stall system and rev limiter. | 
              
              
                | Y | 
                Input Throttle | 
                The original throttle signal that is applied to the model. |

                | RX | 
                Throttle mod indicator | 
                If the signal value is 1 then the rev-limiter is cutting the throttle, if it
                  is -1 then the anti-stall system is modulating the throttle, 0 otherwise. |
