The autopilot I used had no sensor for speed. Does any? It would seem
to me that there needs to be one because response to the wheel is
proportional to your speed underway.

Haven't been paying attention to this thread, but my tiller AP will
"read" some NMEA speed sentence and the swing can be adjusted.
