I had a local avionics tech install the AP 74 (with new servos for pitch and roll and the interface module) in my 2005 VM1 and we've been test flying it. It's connected to a Dynon remanufactured D10A. The heading hold works just fine but the Altitude hold is not holding present or selected altitude. I'm able to toggle thru the Heading, Alt and Baro settings and adjust the heading bug which is followed well and it couples to the Garmin 796 GPS just fine. I can adjust the Barometer setting which seems to be off in the D10A Efis and I can select/adjust altitude but no matter which altitude I select, the AP74 is not capturing or climbing/descending to that altitude.
I'm looking for suggestions please.
Thanks
