Well after another 4 hours of testing changing and looking through a bunch of different options I have discovered what I was missing. When importing a binary file the "Map Edges" don't always default to span the entire map.
If anyone else finds this and follows along everything there should work just make sure to set the map edges to Top:90, Left: -180, Right: 180, Bottom: -90. This also clears the infinity rainfall bug as well. Hopefully my hours of trial and error help someone else out there.

If there is a simpler way to deal with this I would like to know.
