yes! Updated the firmware yesterday and actually, the raw is about 8 times the offset.

saris screwed the pooch with firmware 14.072. Count your blessings that your Joule didn't freeze and go out of commission like so many people running windows7-64 bit did

dhale50

Thanks. Yeah I guess I got lucky because I do run 7-64. I found this answer from Saris just in case someone else is having this issue:

"It has come to our attention that after the firmware was released the torque value that you are seeing is being displayed roughly 8.8 times higher than it should, so until we rerelease a fix you can simply divide that value by 8.8 or expect to see it within the good calibration range of 4400-4611 (500-524 offset). This has no effect on the calibration or accuracy of the powertap it's just in the offset value that is being displayed. A Fix is already in the works for this.

Quarq is returning my unit. Apparently, some electrical device went off kelter, but the strain gauges are okay. I'll have it back by friday. Hooray!

climber7

in the same boat, kind of. one of the buttons on my garmin sort of stopped working. that, combined with the whacked-out speed readings, prompted me to give them a call...they're just replacing the unit under warranty. it'll be interesting to see if that solves the speed issue too.

For all you GC people:

I'm interested in using the Garmin ANT+ usb stick and having it pair with my Powertap SL+ (or Garmin 500) to display whatever workout I'm doing on my computer. It looks pretty straightforward but I was just wondering if anyone had specific experience with it.

Here's some more info about my set-up:
Powertap SL+
Edge 500
No GSC-10 sensor, but I do have one I could use
Mac running OS 10.5
latest build of GC version 3

How do you get gc version 3? i can only find 2 online

It's linked from the Downloads page on the main site.

jsutkeepspining

thanks. downloading it now

shovelhd

It's a LOT better.

jsutkeepspining

any clue how to move all of my old rides over?

shovelhd

I'm pretty sure I just imported them like I would from the Garmin but from the 2.0 directory. It's been a few weeks and I can't remember.

jsutkeepspining

i cant find my 2.0 directory? do you have a mac

crapweasel

On Windows you just Copy/Paste the athlete directory from 2.0 to the new directory on 3.0. Not sure where it is on the mac. The Help -> About menu (or something like that) should have a link to wherever it is on your machine.

SalsaPodio

Not near my home computer now, but it should be under Preferences. You can click on the file path and it will open it up in Finder. Just copy the files to the new directory.

After doing some reading, it seems most people prefer to leave Auto-Pause Off on their Garmin and then remove the stops manually within WKO+ in order to calculate correct power values. However, I haven't found anything about using Auto-Pause with GoldenCheetah. Should Auto-Pause be on or off if I intend on using GC as my software of choice?

Getting annoyed with what seems like a lack of reliability in the Powertap SL+.

1st one died after 1st ride. Messed up transmitter. That cost me a box and shipping.

Before today, the replacement was great. Used it, and now the offset is up to 525 just sitting into my living room. Will probably drift up from there when I ride it. I've had this one a month. Will probably end up costing me shipping again.

At this rate, I will have paid as much in shipping the wheel as I did for the wheel by the time I get a year's use out of it.

Edit: make that 527.

Using Qalvin, i did a calibration of my Quarq, which was recently returned to me from Spearfish. My method was very crude: 2 10-lb plates hanging off of my pedals. The plates are actually 19.8lbs, as verified by both FedEx and UPS, and i'll take it to USPS tomorrow to further verify it.

The result: the factory slope is 8.93 and i got 8.99, which is 0.67% off. I'd say it's pretty damn spot on.

My method was actually not ideal: i don't have a trainer, so the bike will move with plates hanging off of the pedal. Quarq is very sensitive, and the torque reading will change with even slightest of movement. As such, i decided to apply rear brake when doing the measurement. With a heavier weights and a trainer, i'd think you can get very good calibrations.

echappist

when's the last time you rode it in the rain? SL+ is not as waterproof as Pro+

shovelhd

Says who? I rode my SL+ everywhere. Slope never varied.

jsutkeepspining

my (new) sl+ is great. my first one was bad straight out the book, but saris took care of it (and quickly). just checked the toque reading tonight, and my accuracy was within .5 %

echappist

saris. The cut out allows more moisture to enter. Not saying that my SL+ went off kelter in the rain, but it is possible

I expressively sold my SL+ and went for a Pro+ for better water-proofing. Then again, i'm anal about these sort of things and want my stuff to last a long time...

crapweasel

Where are the good deals right now on PowerTaps? I seem to remember a month or so ago people were blowing them out, but I'm not seeing it right now.

(Not for me - I've got power already)

shovelhd

Neuvation. Their base SL+ wheel is $695.00 with their rim minus 10% using code holiday with free shipping. They have about a 4 week backlog. You can upgrade the rims and spokes if you want.

Rob may have something going.

power recording/analysis question:

i'm using a powertap with a garmin edge 500 and looking at the data in golden cheetah. i have the garmin set to autopause OFF and 1-second (not smart) recording. sometimes i'll get off the trainer to adjust something in the middle of a workout, and if i do this, i usually press pause on the garmin. however, looking at the data in golden cheetah, i see a gap. if i go into the editor view, i can see that the time just jumps - for example, from 20:29 to 22:11. this is clearly where i paused the recording, but apparently it's still keeping track of the passing time. is there any way to change this and just completely pause everything, or should i just leave everything running so it doesn't get confused by the "invalid recording gap?" i realize that for the purposes of power analysis, stopping recording is misleading...just wondering, though.
