iFly B737 Max and Mobiflight Presets

[BAW242]

I am having quite limited success with assigning presets on the iFly, for example the Park Brake preset doesn't work, neither does APU start, and I can only get one of the runway turnoff lights to work. I have no issues with any other aircraft using Mobiflight presets. Has anyone else run into problems with this aircraft and any advice? I am not a FSUIPC technical expert but I have managed to use aircraft specific presets for years with no trouble and this one is bugging me!

Thanks

Sorry but I don't have the iFly so cannot look into this. But looking at the parking brake presets, they simply set an lvar value:
  Parking Brake ON: 7 (>L:VC_Gear_trigger_VAL)
  Parking Brake OFF: 8 (>L:VC_Gear_trigger_VAL)

You can check if they are valid by using FSUIPC's logging facilities. List the lvars (Addons->WASM->List Lvars) and note the value of that lvar with the parking brake on and off - does it match those values (7 for on, 8 for off)? Are there any other lvars that look related to the Parking Brake?
If you open the logging  console (Log->Open Console), set logging for Events and Input Events, what do you see logged when you engage/disengage the parking brake? If you see any relevant events or Input Events, you can try using them.

Otherwise, the following tutorials explains how to determine what to use for any given switch/button:

Also, please note that ALL provided presets are provided by the community driven effort led by MobiFlight (see https://hubhop.mobiflight.com/presets/), and any issues with presets should be addressed to MF via their Discord server, on the msfs2020 or msfs2024 channel, depending on the  version you are using.

Thanks as usual John for the time taken to explain! I’ll have a look when I next sneak in some sim time, sadly I used up all my weekend sim credit already!
