    Perfect Pass and 211

    I have a 2007 211 Team Edition. The Perfect Pass is in Digital Pro mode. When I set it up to drive at 36 MPH the PP engages but only accelerates to 30.5 MPH and 3770 RPM. I contacted PP and here was their response:

    Do you use timing to calibrate the Perfectpass? If not you can change
    the baseline manually and manually calibrate the speedometer on Perfectpass. You will need a Gps or a boat speedometer you trust. Highlight the arrow in the upper right hand corner of the screen and press the "v" key. This is the baseline adjust screen, press the "menu" key to highlight the baseline. Highlight the arrow once more and press the "v" key and you will be in the speedometer calibrate screen. You can now calibrate the speedometer to your Gps.

    Just remember the speed is controlled from the Rpm baseline from
    24-36Mph. The set Rpm value is Baseline + Skier weight + 15% of the crew weight
    I'm not running it in RPM mode but MPH mode. The speedometer is accurate but they had this comment:

    Then you have to adjust your baseline value up until your boat is
    holding 36 Mph. Even though the speedometer is accurate it is controlling from the Rpm. Your Rpm for 30 Mph seems a little high maybe a new propeller will help that out.
    I would think a factory installed option would be properly calibrated for the boat. I'll play with this on Saturday when I'm back up at the lake. Does this reflect other's experience with Perfect Pass and the 211?

      RE: Perfect Pass and 211

      I have an 07 211, and I too have problems understanding what Perfect Pass is actually doing in slalom mode. It works great for wakeboarding and surfing, but I don't even use it for slalom, because near as I can tell, it ONLY locks the RPM to whereever you set it in the baseline cal, and does NO adjusting when the boat slows down.

      For example, I had my buddy slalom behind the boat. I set the baseline cal so that it was maintaining 34 MPH (I think it was about 3750 RPM).

      Then my wife, who is lighter and on a different sized ski got behind there, and the boat was doing about 37 MPH. It doesn't look like the PP takes the speed and does anything with it, it just locks the RPM to whatever the baseline cal is? Is this correct? Seems kind of silly to me to do that, but it seems like this is how it functions. The manual is horribly lacking in explaining how this is supposed to work BTW.

        I'm not sure why the prop would be an issue. I assumed CC would have taken care of this during the water test.

          Dealer helped me calibrate mine for MPH. You need to run @ MPH off speedo and see what the RPMis then go and adjust the baseline so that RPM matches the speed. It's easy to do if someone shows you. I used a GPS to get the speed accurate first then adjusted the baseline. Call you dealer they should be able to explain it better than I did.

          I changed the prop on my boat and had to re-cal the baseline due to rpms were differant with the new one when at the same mph. EX. had to adjust baseline rpms up to go same mph as before.

            That shines some light on my PP problem also. I was trying to set RPM first then calibrate speedo.

              So I'm a suppose to set the RPM in the calibration screen to the RPM value I read when driving at 36 MPH? Do I need a skiier back there pulling hard? Some how I can not comprehend why RPMs is needed for calibration. If PP says the boat is going 30.5 and I want it to go 36, PP should increase the throttle.

                go back and read what you posted from PP in your first post.
                from 24-36mph PP is using RPM, not the speedo, to figure out what it needs to do. So, in order for it to know, you have to tell it what RPMs achieve 36mph in your boat.

                  You realize how dumb it sounds that you need to tell PP what RPMs it needs to achieve 36 MPH when it has a speedo! It just does not make sense other than it is a poorly thought out calibration process.

                    It sounded like you didn't understand how it worked. I was only trying to help your understanding.

                    I would imagine that as those speeds, RPMs are more reliable than the speedo. That might be the reason for using RPMs. Or the reason could be that the earlier systems worked off of RPMs only. I have an old system that in only rpm based, no little wheel under the boat. Whatever the reason, that's how it works.

                      I didn't intend to imply you sounded dumb, just Perfect Pass sounds dumb. PP has two inputs, RPM and MPH. It should be able to figure out what is a suitable RPM range for a desired MPH. Your explanation that PP historically only used RPM provides a glimmer of understanding to this configuration process.

                        After re-reading the manual and following PP tech support instructions I got the PP to hold 36. I didn't get a chance to ski behind it so see how it works with a skier but I think I have it figured out. I finally got it through my thick skull that at slalom speed PP uses RPM and not the speedo to hold the boat at the correct speed.
