Table of Setup Codes and Parameters
Description Code Values of the Parameters Factory
Helm Displacement 269 .1 to 6 by .1’s 1.7
Pump Displacement 169 [Up Arrow] for 4 liter, [Down Arrow] for 2 liter 2 liter
Turns Lock to Lock 26 .1 to 10 by .1’s 4.5
Sloppy Linkage Compensation 257 8 settings, 8 for most sloppy 1
Code 257: In case of sloppy and loose steering linkages, increasing this parameter may help to reduce heading
oscillations due to the linkage. Use with caution.
Shadow Drive Desensitize 368 1 most sensitive, 40 least sensitive 20
Code 368: If the shadow drive is being false tripped, i.e., autopilot is disconnected when the helm is held
still, increasing this parameter may help. False tripping is usually due to leakage of uid past the helm pump
lock valve. You may need to repair the helm valves if you cannot eliminate false trips.
Shadow Drive Enable 367 [Up Arrow] for On, [Down Arrow] for Off on
Reversed Hoses 249 [Up Arrow] for Reversed, [Down Arrow] for Normal Norm
Code 249: In case of hoses installed backwards, use this code to electronically reverse the steering direction.
Description Code Values of the Parameters Factory
RPM Source Conguration 259 1, none/ 2, Port/ 3, Starboard/ 4, Both 2
Code 259: For single engine installations, set this code to 2 (1 blink) (and hook the blue and black wires up to your
engine tach leads).
Pulses per Revolution 267 1 to 255 by 1’s 6
Code 267:
The number of tach pulses per engine revolution is an engine specic parameter. The following settings are
a good starting point, however you need to verify them on operation. V8 engines 4 ppr (3 blinks) Most outboards 6 ppr
Show Port RPM 35
Hold Down [Select Load] button: 1000’s blink on
Up Arrow 100’s blink on Down Arrow
Show Starboard RPM 36 Same As Above
Transition RPM 348 100 to 6000 by 100’s 3000
Code 348: Set this code to the RPM’s that your boat runs when almost on plane.
Low RPM Limit 357 100 to 6000 by 100’s 500
Code 357: If your autopilot runs well at all RPMs but is a little too active at idle, you can increase this low
limit RPM to a setting that is higher than your idle RPM to reduce autopilot rudder activity at idle.
High RPM Limit 359 100 to 6000 by 100’s 6000
Code 359: If your autopilot runs well at all RPM’s but you would like a little stiffer heading hold at the top end,
reducing this setting to an RPM lower than your actual peak RPM will help
