Resurrecting this thread as I was using it to try and fix a problem...
I've been having problems with my Perfect Pass Wakeboard Pro on my '08 X-15 surging and/or slowing way down when I hit rollers, especially if it is multiple rollers when a couple boats pass. I went to play with the settings as suggested above to see if that would fix it and got confused. At least in wakeboard mode, mine only has KDW and not CS or NN settings. Are these other two in a different menu somewhere? Or in a mode other than wakeboard mode? Or is there a firmware update that I missed somewhere? Looking at the instructions in the pdf earlier in this thread, I've never seen that screen with CS and NN. Mine goes straight to the named riders list where only KDW is available.
If I can't get this sucker working better, I may fork out the $500 and upgrade to Stargazer so I can bypass the paddle wheel driven problems.
