One more bump...

Anyone out there interested in trying to solve this?  I have a full-size 767 cockpit that I am desperately trying to port over from LD767 and FSX to P3D CS767 and need this functionality.

Summary: Need a C++ way to Read/Write CS767 LVARS.

Specifically, It looks like I need to build a custom gauge DLL (that is in-proc w/ P3D) that can r/w the LVARS in CS767 and then does an IPC (maybe socket) to a module that can talk via SimConnect or FSUIPC and my OpenCockpits Modules.
