Good afternoon, I was wondering if there is a way of changing the default SELCAL code in the iFly 737MAX from MS-BD to the real code that some of the aircraft that were delivered by Boeing have in real life?
Modified title to better explain the question being asked by the OP.
I certainly wouldn’t attempt to alter anything, as per the memo from iFly:
“Any modification whatsoever of any file in the “ifly-aircraft-737max8” folder in the community folder will brick your installation of the iFly MAX8.”
Is this just for cosmetics or flying on VATSIM? as the “hard coded” one has no impact, just put the real one into vPilot.
It’s just for cosmetics, wanted to make the experience more authentic and I was just wondering if there is a way you can change it, that’s all. Wanted to make the PFD look a little bit more diverse 
YES YOU CAN, you need a .ini file that is it at the work folder (you can access there from the ifly manager). you can use files already done by the same people that made the livery like this one SpiceJet VT-MAX || iFly 737 Max 8 - Aircraft Liveries for MSFS | Flightsim.to
