I know in the example I posted with it, it's 2 directions away, but what would be the formula to do this? The problem arises since, like in the example, dir1 is 15, and dir2 is 1, so abs(dir2-dir1)=14.
If any of this makes sense, any advice?

I would suggest just doing something like:

dist = abs(dir2 - dir1);
if (dist > 8) dist = 16 - dist;
