I've rewired it once already, and made sure the ground is good. Next I think I'm going to make sure its getting good power.
Its not always stuck on 14.5 it moves +/- 0.1 once in a while, but its completely random. Usually between 14 and 14.6.
I've re-calibrated everything and updated the firmware and no difference.
