Question on Perfect Pass

[skijones]

Hello, I installed Perfect Pass in my 99 SNOB and am unable to calibrate the digital speedo. Since I do not have access to a slalom course, I am trying to do it manually

I did the master reset, but am still reading 5-6 mph slow on the speedo in slalom mode.

Since this is rpm based, what do I need to do?

Is is possible to pull the paddlewheel while the boat is in the water?
It is currently in the dock and I would hate to have to pull it back out.

Any help would be appreciated.

get a GPS

Have a GPS, just can't figure out how to get the dig speedo to match actual speed.

If you pull the paddlewheel, you'll have a 1.5" hole in your hull which will let quite a bit of water in. Your speedo reading on PP is coming from the paddlewheel all the time. In slalom mode, the system is not taking input from the paddlewheel to make corrections but the real-time speed is coming from the paddlewheel. I'm guessing you have something wrong with the paddlewheel. They do wear out and need to be replaced from time to time. it is a quick and easy replacement but you might want to pull the boat to do it.

RE: Question on Perfect Pass

Are you attempting to calibrate RPM based speeds (over 24MPH) or speed based 23MPH or slower. There are two modes in Slalom. If you select a speed 23MPH or slower the system controls speed via the paddle wheel. The two different modes have different set ups.
You will of course have to set the values for each speed separately in RPM mode.
Make sure your skier value is set to zero when calibrating and that your crew weight is properly set.
Have you got the user manual for PP. There are some good instructions here for both modes. The latest 6.5NG version can be downloaded from:

Understand all that, but how do I change the dig speedo readout to match the rpm based actual speed? I can get the actual speed the PP holds right, 32.4, but the dig speedo is off.

Again, my guess is there's something wrong with the paddlewheel. The 32.4 mph is merely the "label" for that RPM setting. The paddlewheel is always reading your actual speed for the digital speedo. Another possibility is that you have the wrong RPM set up for 32.4 and your digital speedo is telling you the actual correct speed.

Is the dig speed on the perfect pass display allways off the paddlewheel?
This is a brand new out of the box, but I am new to setting one up. Yes, the arrow on the paddlewheel is facing forward.

I can get the system to hold actual speed( per gps and speedo), but the digital display is off 5-6 mph slow. Did speedo calibration, no help.

Sounds like I have a paddlewheel problem, but will not know until time allows me to put it on the trailer...Thanks

Is it possible that the paddle wheel base isn't installed perfectly straight causing it to drag a little?

OK, I have kind of the same question. I'm new to the whole perfect pass thing.

I have it working pretty good for surfing and wakeboarding, but I'm confused by the slalom mode.

Is it purely RPM based? The speedo display is just that, right, a display? It doesn't seem like it tracks the speed at all, just locks the RPM in slalom mode. And the BaseCal RPM number is the only way to adjust that.

Also, the not being able to delete a name without resetting is really lame. They make it easy enough to accidentally add one in the selection menu. It should be easy to remove it.



For the original poster, there is a paddle wheel correction factor on the setup somewhere. This is where you'd get the speedo to match the mechanical speedo in the boat.

You may need to calibrate your paddlewheel speed by getting a speed slower than 23 MPH dialed in. This will automatically calibrate the paddlewheel for all speeds less than 23MPH and I'm guessing it will then read accurately for your faster slalom speeds. Also, you need to calibrate every slalom speed above 23MPH.

I think your answer will be on page 8 of the user manual under the section headed "Additional Slalom Information > Setting Baselines / Calibrating speedometer without a course".

I was going to test my digi speedo but the weather was really bad this weekend as such, I didn't get to the lake.

I know some people who only slalom, have not drilled the hole for the paddle wheel. I didn't know they didn't have a PP speed reading without the wheel. Would be interesting to test the RPM based speed reading with the paddle wheel unplugged.

[skijones]

Been all over the manual. I did get dig speed close to acutal at 20mph, but have not had any luck at 32.3. Will have to check the paddlewheel.

Keep in mind that alot of slalom courses use magnets on the guide buoys for speed adjustment in the slalom mode. There is odd ball and all ball magnetic setups. If you are using this method you do not need a paddlewheel as the PP does not use it for anything above 24mph.

[NigelC]

Sounds as though you are set up at the lower speeds (speed based). Just need to get the RPM based speeds sorted.
I would be interested to see if the speedo reads (right or wrong) with the paddle wheel disconnected at 32.4.
I won't be able to test this until next weekend.
I am assuming you are running 6.5NG as this is a recent install?
As you have no slalom course reference. Have you checked the average speed in opposite directions to compensate for wind, water flow etc?
