I recently updated my panel with an 2 tube Aspen Evolution to go along with a King KFC 200 autopilot. I also installed a EA100 autopilot interface. Before updating my panel I did not have any issues with my autopilot at all. It was rock solid, held altitude well. However, now im having slight pitch occillations which feels like someone is bumping the controls. I have been to two avionics shops or of which consulted with the Aspen rep in the area however to problem still exist. The problem isnt continuous and comes and goes during the flight. Does anyone have any ideas? Im about to pull my hair out..
