Autopilot

An important setting is drive type = 2.

 Calibration Lock             OFF
     Pilot Type               4000whl
     Rudder Gain                 2
     Response                    2
     Turn Rate Limit            20
     Align Rudder               0
     Rudder Limit               20
     Off Course Alarm            20
     AutoTack                   100
     AutoTrim                    3
     Drive Type                  2
     Variation                   0
     AutoAdapt                  nth
     Latitude                   The correct latitude for 
                                the location of the boat.
     Rudder Damp               4
     Cruise Speed              A

These settings sort-of work.  You will still get a wake snake, but they
are much better than the original factory settings.  At least one C-320
owner has installed the rudder position indicator on his boat (look in
the C-320 photo archives), and that may help.

I have been using these settings for the past four years with my
ST-4000+  on my C-320, and get a minimal wake snake when steering off
the fluxgate compass under power.  However, when I use either the wind
instrument or the GPS to control the direction (yeah, yeah, I know, the
wind instrument just provides some adjustment to the fluxgate control,
but what can I say), the boat runs straight as an arrow with no wake
snake at all.
