Perfect Pass Problem Yesterday

I took the boat out yesterday and did some wakeboarding. I turned the perfect pass on and was using wakeboard spd trying to hold 21 mph. The perfect pass would take over but the speed was all over the place. It would hold the speed about a mile per hour under the 21 it was set at but it would make too big of adjustments with the throttle so the speed varied. I have used the pp here in Colorado a couple of times and it does this sometimes and works sometimes. It seems to not not work correctly now most of the time. I just bought the boat and it was originally in South Carolina so I am wondering if there are some settings that need to be changed now that the boat is at altitude. Any ideas?

Boat is a 2005 x7 LQ9 1:1 12.5x13 prop

Assuming your 2005 isn't wired into the Indmar TBW system, make sure the PP servo cable is tight against the throttle link - slack there will cause significant speed variations. Perform a servo-tightening excercise as described in the manual. Calibrate the PP speedometer against a GPS. If those things are OK, you'll have to adjust the settings in the computer. KdW and NN. You may have inadequate paddlewheel sampling. A lot of people will use PP for wakeboarding in RPM mode rather than speed mode for this reason.

My Perfect Pass holds speeds very closely in calm water. If there's a little bit of chop, the paddlewheel loses contact intermittently due to its awkward placement on my V-drive hull and the speed can surge back and forth by 1-2 mph.

I called Perfect Pass yesterday and checked my settings...The CS was set at 1450 or so and was supposed to be 830. Aaron at Perfect Pass thought this was probably the problem but I will test soon to make sure. Just thought I would post this just in case anyone else had this problem.

The NN was a little high as well at 130 and was supposed to be 100.

Hopefully this helps someone.

Once my perfect pass was all over the place as well. Turned out some debris had bent the rod the collector wheel spins on...and I guess that was sending strange rpm data to the unit. Weird, but an easy fix for me.

dont know what the x7 comes out to be, but on our 07 197 someone got it into the trailer bunk and bent a tab over into the paddle wheel and it quit working all together. It was an easy fix, but I'd check your trailer carpet and see if you can see where it was hitting.

If you're not running any ballast, that may be a bit of the issue too, based on my limited amount of experience. Your engine is huge compared to the required amount of power to move the boat @ 21 mph for the little X7. When the controller asks more a bit more, the engine is sending too much since it has a lot of ponies. Hopefully the settings will fix that.

We had similar issues in our 205 / LT1 combination. Always had to use rpm for wakeboarding. Added 2 fat sacs this year & it works great in speed mode. Although I never had a lot of time to mess with the settings, just a simple observation. RPM gives and OK pull for the empty boat (and novice boarder), just slows down a bit when you turn around.

hey, I have the PP DBW system and they had SEVERAL software updates to combat the surging or inconsistent rpms when in wakeboard mode... DId Perfect pass ask which version of chip you have?? Had it worked properly in prior seasons?
