AoA on D10A is pegged

[cschanche]

Finally getting around to trying to solve this issue. The AoA has always been pegged at the top of the red zone. I tried calibrating it according to the procedure, nothing changed. I have the D10A and the Dynon heated pitot with the upgrade of a few years ago.
Just wonder where to start: is this a pitot-static issue, or is it electrical?

When you're in calibration mode, the AOA scale is showing you a more direct measure of the relative pressure between the pitot and aoa ports. It's not AOA, strictly, but it should be mobile during the calibration. If that's not the case, check the AOA line continuity from its port in the probe back to its connection on the D10A. If that checks out, there may be an issue with the D10A itself.

And of course, re-read the calibration procedure and make sure you're understanding the steps. Misunderstandings there have yielded poor calibrations too.
