Garmin Reactor 40 Configuration Manual
Adjusting the Autopilot Gain Settings
The autopilot gain settings are set during the Autotune procedure. Adjusting these values is not recommended,
and you should record the values set by the Autotune procedure before making any changes.
1 On a helm control or the autopilot screen on a chartplotter, select
Installation Setup > Autopilot Tuning > Rudder Gains.
2 Select an option based on the type of boat:
• If you have a planing-hull powerboat with the speed source set to Tach. - N2K or Proprietary, Tachometer,
or GPS, select Low Speed or High Speed and adjust how tightly the rudder holds the heading and makes
turns at low speed or high speed.
If you set this value too high, the autopilot may be overactive and attempt to constantly adjust the heading
at the slightest deviation. An overactive autopilot can drain the battery at a faster-than-normal rate.
• If you have a planing-hull powerboat with the speed source set to Tach. - N2K or Proprietary, Tachometer,
or GPS, select Low Spd. Cntr. or High Speed Counter to adjust how tightly the rudder corrects the turn
overshoot.
If you set this value too low, the autopilot can overshoot the turn again when it attempts to counter the
original turn.
3 Test the autopilot configuration, and repeat step 2 until the autopilot performance is satisfactory.
