I have been using signed(A)/2 on my 2013 Ecoboost Flex
What is the difference between these two equations? Is one more accurate?
PID 2203ec
signed(A)/2
or
signed(A)/2+(B/512)

If I'm remembering the difference right. The latter one breaks it down into tenths vs. 1/2 degree.

That is correct. Just finer resolution. You'll still get close but could be off by a degree. In other words a 2.9 would only look like a 2 since it truncates the decimal...I recommend you use the second formula.
