The ECU translates the throttle pedal position into adjustments in all those controls to make it behave the way the driver would expect a traditional throttle to work. Given the complex interactions occurring in a system developed in the early 2000's, when drive by wire was still relatively new, I can only imagine the engine management in Traditional throttle controls involve a combination of a mechanical cable connected to the throttle and the gas pedal. Though this system has worked extremely well, electronic throttle control differs in that the gas pedal sends an electric signal that opens the throttle. Brake-by-wire. Another drive-by-wire subsystem is brake-by-wire. Throttle. The throttle should have linear sensitivity. See Throttle Calibration Guide. Keyboard Mapping for Pause Function. Make sure that the Pause function is only mapped to the Esc key and not to any other key as otherwise this mapped key will trigger Pause in input fields of the EFB or the MCDU when using the keyboard input mode. Windows LocoNet is the throttle network designed and used by Digitrax to communicate between throttles, command stations, boosters and other accessories. Interfaces are available to allow a computer to be connected to LocoNet. Several other DCC Manufacturers also employ LocoNet as their throttle network. Throttle Networks. .
