[CA] Autopilot not steady, constant small corrections
I have an evolution EV-1 with and ACU300. Hydraulic steering. Just recently updated to Lighthouse 19. Since the update the autopilot makes constant 1-2% course corrections. This happens in calm seas and in all three sensitivity modes. Any idea on how I can get it to just steer straight?

Thanks
