FWIW just this week I was on a boat with a (fairly new S1 series Raymarine) autopilot that was just way too abrupt. A course change of 10 degrees in any direction would result in a wild swing of at least 30-40 degrees in that direction, then a (sinusoidal decaying) correction. It did not appear to be a fluxgate (because fluxgate did show the heading as it was, i.e the abrupt swing and all). It was not one of the settings either (I am somewhat familiar with Raymarine autopilots and went through all the settings including the re-initialization). Something "else" made it do that - but what I do not know (and I left it at that since it was not my boat).
This probably does not help, but it can add another point to ponder. It did help me to input course changes one degree at a time though, which may be a nice feature for autopilot controlling software - feeding new bearing to the autopilot incrementally over a period of time.
