GPS Speed Control and Solar Flares

Alrighty.  Seems we have a result---nobody is worried about it.  6.5 is just a button push away for me.  Plus, if the boat thinks it's 10 meters fast, maybe I can catch a break.  Over the past several years, I've read so much being made over .02 seconds difference in times.  Glad to see the focus shift back behind the boat.

 

Ski on!

Maybe once per session (or less) my PP StarGazer will freak out in mid pass, lose signal, and start accellerating for no aparent reason.  We blame it on something interferring with the signal i.e. solar flares, bad karma, whatever.  Doesn't happen often but does occur resulting in a reride (it's practice, WTF?).  Anyone else?  FWIW I still think SG is the most user friendly speed control out there, I never go back to Classic mode.

I just installed SG on my 03 CC. Does anyone have any input on getting everything up and running correctly? I went out to the river and tried the capture mode, which worked well up river, but not with current. it kept surging around 70 rpm or so??? Current is around 2mph? I'll be going to the course next for baselines.....

Thanks for any suggestions!! Cool

We had a discussion last summer about the speedup issue. For servo models on some boats it seems the "inverted tach" setting is needed to deal with a dirty rpm signal. This worked great for my '99 RLX. However, very infrequently, we'll enter the course slow as if never locked by GPS and then get an extreme correction a 3 ball. It's very rare, always at one end of the course, and we think it's only when spinning several passes.

 

Capture mode is OK for getting things close but if your rpms are drifting up and down significantly, try "inverted tach" to see if it settles things down. My opinion is to use the regular calibrate mode. It doesn't not use the GPS, but times a virtual pass, so you can do it in open water. When you get good times both ways (watch out for wind), you're ready for GPS mode.

Deke - the Broho lake is a fairly short set up, so if the driver over does it coming into the 55's, then SG will slow down before the gate, but then have to speed up again at 3 ball.  I think some of my GPS problems are induced by my not being smooth enough on reaching speed when coming off the island.  Last week a crew weight of 200 worked even better.
