You are quoting from the instructions to install the MobiFlight module. This module does nothing by itself, it just enables some of the SimConnect events that are currently not enabled by the sim itself.
To make use of these events requires the use of other software of which my app is one, others being vjoy+joystick gremlin, the full MobiFlight suite and others that don’t readily spring to mind.
If you own a Bravo throttle my app should just work out of the box - albeit that it might not have exactly the mappings that you want. Changing the mappings is currently done by editing the JoystickMappings.xml file with any text editor.
