Hi,

I've got a 2 year old Evo 100 wheelpilot. It's been updated to what was the latest software back in December 2018. I need to lower the gain but when I go to - Menu>Set-up>Autopilot Calibration>Drive Settings, my only options are Rudder Dampening, Auto Turn, Motor Phasing, Rudder Limit and Hard Over Time. Where is the Gain option?

Thanks, Frank

Hi Frank,

What's the reason why you need to adjust Gain on your pilot? The Evolution range don't have a fixed gain. Older or less intelligent pilots had a fixed rule that applied a certain amount of drive output in order to achieve a certain change in course without regard for whether that course change is upwind or down, up a wave or down into a hollow, and of course that means that sometimes they'll apply too little helm and sometimes too much. Instead, the Evo pilots steer like a human helmsperson does: they use their accelerometers and yaw-rate sensors to feel how the boat is moving in response to the helm and apply more helm or less from one moment to the next as required.

Usually, when people want to adjust gain on an Evo pilot it's because there's another problem: adjusting gain is only a workaround, not a true solution however. If you can let me know what the key problem is, I can recommend some more appropriate solutions.

Tom
