Note ! The values in the table are factory set (default) and listed for
information only. After having performed the Autotune, the values
may differ from those listed in the table. It is recommended that you
write down the parameters "learned" by the Autotune prior to making
any adjustments.
The two most important parameters that determine the
performance of the automatic steering are Rudder and Counter
Rudder.
Rudder sets the rudder gain which is the ratio between the
commanded angle and the heading error ( P-factor).
