PROBLEMAS ASIGNACIÓN COMANDO ENCENDIDO APU

Holaaa.... a ver si me sabeis sacar de este atolladero porque no soy capaz y no lo entiendo.

Tengo asignado el encendido y arranque de la APU del A333 que vuelo a una tecla de un teclado numérico de la siguiente manera.

Numpad-7 <NONE> sim/electrical/APU_start

y el apagado a

Numpad-4 <NONE> sim/electrical/APU_off

El problema viene cuando asigno ese comando en el archivo.ini del avión que maneja los paneles saitek y que corre con flyLua, que enciende la APU (en la pantalla se ve encender la luz verde en el botón de la misma), pero no la arranca, siendo ambos el mismo comando.

He visto que hay muchas configuraciones para aviones concretos que arrancan la APU, pero usan creo comandos específicos del avión, y no el genérico como hago yo.

Gracias por adelantado.
