Rate of Turn Setting

If you have a large boat, it would be best to update to the newest software that offers new settings to deal with large boats that have single screws that tend to be harder to steer. The new software has done wonders for many Nordhavn Yachts and like.

If you have to do a big turn (say 60 degrees) to follow a route, it smooths out the turn instead of tossing you out of your seat when you hit the route waypoint at speed. 5 degree per second setting; it would take at least 12 seconds to do the turn. Rate of turn is also an output so that AIS can broadcast it, etc...
For wandering, the software update would be easy, but also check the basics like the linkage to the rudder feedback is not sloppy, the rudder isn't loose and it's shaft is moving around where it shouldn't, After the basics are set and dockside is done again, then the last step would be to move to sat compass for heading.

I already have an SCX-20 satellite compass for heading source and my rudders have no play. The issue is related to how the autopilot steers. Sometimes it will stay within 5 yards of a course line in NAV mode, sometimes it will get more than 20 yards off before initiating a correction and then overcorrect to the other side of the track. It is not consistent, which makes it hard to diagnose. When I steer manually, I have no trouble staying very tight to the course line with very few steering motions. But that isn't a lot of fun running 100 miles each way out to the canyons to fish.
I will figure out how to install the new unit software and see if it makes a difference as Johnny suggested.

I did the update on the processor and control head. I verified that they now have the latest version installed (1.30 for the processor and 1.11 for the controller, which were formerly 1.27 and 1.08). The menus look almost exactly the same as before. I did notice a ship characteristic choice of "WB01 and WB02" that I do not remember seeing before.
Also contrary to what the instructions said, my settings all seem to have been preserved.
What am I missing? I have not tried to use the autopilot since the update.

I was able to try the autopilot with the new software today. I am not sure whether it is materially better. When I first turned it on in NAV mode, it did astonishingly well for a couple of miles. It stayed within a 2-3 yard cross track error. I stopped watching it for a while and it had deviated 15 yards one side and then corrected and went 15 yards on the other side. I tried the new boat characteristics settings and they didn't change anything noticeably.
Trim tabs fighting with a pilot at same time is never a good thing.

Not using the trim tabs is not an option. I am not changing the setting frequently but I am sure the boat's steering behavior is somewhat different when the trim planes are lower because of a heavy load or rough weather that requires running more slowly than when running fast with a small amount of deflection. I can't be the first person to experience this issue given that virtually all planing hull boats have trim tabs.
How exactly does the "full auto" response mode work? Does it make rapid changes in how the autopilot steers?
I know of no autopilot that will adjust to actively moving trimtab system. If the trim tabs are set and not touched the rest of the time, yes it will normally feel the change and adapt but if trim tabs are actively adapting and moving, no. It will cause negative effects to some level.
