As I posted, I did not know why the setting of the Turn Rate Limit to 0 would help. Here is the reply from Dynon. As I said, they are very supportive.
There is an alternate set of control algorithms which may improve roll performance in some aircraft. To try this mode simply set TRN RT LMT to 0. The autopilot will more directly control bank angle instead of targeting a specific turn rate. The maximum bank angle that the autopilot allows continues is still limited by the BANK LIMIT parameter. In this mode, set the BANK ANGLE LIMIT to the maximum value you want the autopilot to use in a turn.
