A boats steering parameters found by Autotune can be looked at and if
needed changed under this menu item. The steering parameters can
also be set to values manually instead of performing an Autotune. The
parameters are divided into two sets:
• HI = Steering parameters to for automatic steering at HI speed
• LO = Steering parameters for automatic steering at LO speed
Note ! As a sail boat's steering characteristic is very much dependent of sail trim,
the parameters may be optimized manually from values found by Autotune.

parameters
Note ! The values in the table are factory set 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).
