What did you find? Those have been scare finds in Ontario lately!

 

Love it, and you have a zbox! Much more interesting then my fuel economy request!

Would be great to see more zbox data- abc123 settings, turning up the zbox value etc. if you had access to a zo boat, you could probably tune your boat to behave very very very close.

 

@GSchmid I wish I knew more about the the ball settings as well, and what they mean/do to the system. I understand the concept that more rpm is needed through the middle of the course and can back off near the end..but its just such a random sequence of numbers! I would have thought, that especially with zbox, that the respond to the pull would negate the need to dial in rpm ramping based on ball timing.

 

At one point during my testing and adjusting the system, I was no longer able to ski my harder passes behind any other boat then mine. Settings were grossly different then stock and I was chasing bouy times. I came to the assumption that I had dialed in my boat to behave according to my mistakes/poor skiing. So it would slow me down for my poor/late 3 ball and make up the time on my 5-6 strong pull.

 

I still believe that some of this exists. That the departure from the stock settings is accommodating the longer line skiing, and that if a shorter line better skier was to ski behind my boat we'd start to see some slow ball 3 times again. But for now..it's at least pulling consistent times and my ball count and feel is similar to the ZO boat I also get to ski.

Garmin has an update for the pucks. It fixed mine right up.

I made a cable to do the update, or send it to perfectpass.

 

I'd love to see at what RPM is your best fuel efficiency

I think I've changed my opinion on the stock perfectpass ball settings. I set them all back to stock, and calibrated my baselines yet again, this time trying multiple calibrations as they would vary by 10-20rpm and average them out. No Skier times in the course were mostly 00, with the odd +/-.01 occasionally showing up. Next my wife on Light and myself on Normal spent an afternoon running repeated passes at one official speed lower then our normal passes to get consistency on SG mode (no zbox). We ended up with:

L: 08/35/40

N:10/35/35

Ball times were all good, again with the odd +/-.01

Added back in zbox at B2 and stock setting of 08. Same results.

Zbox at 10/12 - was really standing me up after the ball, couldn't make my hardest pass at all.

Back to zbox at 8, and feels right again.

Pulled a few other(and better) skiers at 34mph on normal into 32'off and boat times are still solid.

I do think that if we were into shorter line skiing, going beyond 32'off that the ball 3 times would start to appear on the slow side with these settings, coming back to my change in opinion that the stock settings are probably pretty bang on for those hard shortline pulls. That's if your baselines are bang on.

I'm beginning to think that the major deviations from stock ball settings and high zbox values are a result of baseline calibrations.

Pretty sure it was 2011. I had one, can’t recall coat but should be similar to the Union pricing.

Open water - Graphite.

I have had 3 builds, Alloy, Graphite, Lithium. Graphite was the best middle ground for open water. It took me a year to get use to my Lithium after the Graphite - it was just not forgiving at all in open water conditions. It took quite a bit of form improvement and seat time to get comfortable on the Lithium. The graphite was forgiving but also had the performance when you wanted it.

raised my Ball 1 to 15 (Ball 3 remained at 30, Ball 4 to XIT at 35) and got this:

0: -0.01

1: +0.01

2: +0.02

3: +0.04

4: +0.07

5: +0.01

6: +0.01

 

Accidentally though, I had Zbox turned to 20 after running a test with my wife free skiing to see if the zbox was reacting.

After adjusting zbox to 10, I got:

 

0:-0.04

1: 0.01

2:+0.04

3: +0.07

4: +0.04

5: 0

6: -0.02

 

Interesting that the first pass (zbox at 20) that the boat skied awesome and I was early at all bouys, also note I was slow times at all bouys.

Second pass the boat skied like crap, with huge slack at 1 and 2.

 

I'm interpreting this to increase ball 3 to 35? Thoughts?

 

Interesting the zbox number at 20 felt so good.

Any boa product is lifetime warranty. Go to the boa website and fill in the questionnaire and they’ll send you parts no charge. Great service.

Shushwap is great, but I also found this:

Note pricing is in USD though.

@WoodySkier I'm also on a 2017 Senate Lithium, 22' 32mph skier. The 2017 Lithium is no slouch for creating speed. Any downside moving to the Pro for you?

Finally got a few really consistent passes in @22'off and I'm repeating this times now in consecutive passes. Given the deviations what would you change to fix up the slow 1/2/3? I'm guessing the slow final time is due to the slow 1-3 times.

 

0: -0.01

1: +0.03

2: +0.04

3: +0.01

4: 0

5: 0

6:+0.03

 

Ball 1 :10

Ball 3 :30

Ball 4 to Exit: 35

I just did this on a 2002. Not sure how much different the 2001 is - but all I had to do is remove the motor box and the floor panel and I had easy access. Mine muffler did have a crack, I was chasing a leak for a year before I narrowed it down to it. Sanded and fiber glassed the crack and its been all good!

Yes I meant F,L,N ,XL

@"Keith Menard" what weight setting are you running 34.2 at? You may want to try a lower weight class for 32.3 mph, with the same ball settings as your current weight/34.2 ball settings. Looks like at 32.3 it was pulling you in a bit fast and then trying to recover. Since you're seeing perfect 34.2 times in current weight setting.

Couple nice nice Nautiques and ProStar's in Ontario right now. With the dollar you could be picking up a newer boat then expected for the your $10k budget. Look on kijiji

I'm really close now as well. I'll see if I can get a SG/B2 comparison next time out.

Need your version to help. If its original, likely v6.5 Manuals are on perfectpass website.

If its been upgraded, still need software version as different versions have different functionality.

I just recently made an upgrade cable for my perfectpass gps plug and updated the software. Big improvement in performance and no more dropouts.

@Edmund Yes you can change speed while engaged, we do it all the time. Both Practice mode and Slalom mode will allow the change

@skuboyny can you upload your numbers into the googledoc if you haven't done yet?

@KalebP Great to hear! Happy this data is helping getting boats dialed in.

FWIW, my 02 SN GT40 would throttle pretty aggressively with ZBOX at 12 and KX N.

 

I've now done a system reset and working from stock again to see if I can get more consistent results. I did the latest Garmin update as well and its locking on quickly now and didn't drop satellite connection at all this morning or run away on me as it has on occasion prior to the update. More run time needed on this.

TRA is awesome. We have 3 in our family. The 2017+ version is significantly lighter then the 2015 we have, and is generally preferred by all the kids.

K gotcha. It was just me in the boat both times, but I was trying to figure in the full tank of fuel at calibration versus less then half a tank during that run.
