I have an '06 Outback V whose Perfect Pass is surging. I've checked the cables for kinks & tried several different nn & kdw calibration settings. I've read all the posts I can find on the forums but I'm left with a few questions:

* Will someone please share their KdW & NN settings with me? Our boat seemed to behave best at 140/140, and the PP manual says 80/120 is the factory setting and has vague suggestions like "heavy boats may need higher values." What's a heavy boat? Surely an OBV w/ 4 people and no ballast isn't "heavy," is it?

* The PP manual doesn't give any tips like "set the KdW first, then NN" or "if you get as low as 90 on the NN, you've gone too far." Anybody have any recipes for how to calibrate? Trying every setting from 80-200 on the KdW and 90-150 on the NN would be 72 different variations, and that's just going by 10's.

* I've seen a number of posts that say the cables need to be zip-tied in place. I don't see any movement in my cables, but really I wonder: isn't the point of that style of cable that the outer sheath stays the same length (even around curves) and the inner wire is what actually moves? So wouldn't zip-tying the sheath accomplish little or nothing?
