I don't know if it will help, but I opened the flight plan files with notepad. The resulting display had several lines, but not a bunch of random confusing letters, numbers, and symbols, I could read the fixes, and tell where it started, stopped, turned, etc. Perhaps it would be as simple as changing the extension from .ifp to whatever extension the Dynon uses. Or, if you can see a Dynon flight plan file, you might be able to compare two identical (iFly vs Dynon) flight plan files and see how they differ.
