Long time PT user but after some time away I was fortunate to purchase a very nice barely used Cyclops 65mm carbon clincher G3 wheelset. Out of the box paired nicely to my Garmin 500 with 3.0 software (reading the features of the 3.2 and 3.3 I am tempted to upgrade but not until others have reported better success). When I did the calibration I came back with very low numbers below 500 but it was very cold in my garage. Went for a short ride when it warmed up and the numbers came up 449 YET THE WATTAGE NUMBERS WERE SIMILAR to what I am accustomed to. I called Saris and was disappointed to find out that their response was that I could send everything in and they would fix everything for $350 and I would get a year warranty. My question is
whether it is possible to have accuracy from the PT despite the Edge 500 insisting the calibration is off? I ask because the hub SW is 32 and HW is version 2. In the alternative what about slightly pushing on the pedal while it is calibrating to generate a higher torque value, lock that in, and disable auto-zero? Tomorrow I will have my wheels compared to a calibrated quarq and then I will also perform the stomp test unless someone else has some information along the same lines.
Regards.

I was wondering if anyone on here was having issues with the latest garmin 500 firmware, and powertap pro/g3 ? Are there any issues here known to Cycleops ?
I had a replacement torque tube for my sl+ hub in August, and then that one went bad (initially reading low by about 10%, and then went crazy and calibration went off scale)
Then I had a loan wheel for a couple of weeks and that also seemed to read low by 10%. (have I lost fitness!!??)
But then I got the my wheel back with a replacement torque tube. Now the numbers seem right (I haven't lost fitness :))
Good numbers for a couple of weeks...
Then I get a calibration of 450, and the power numbers are nuts. Stop after 10 mins and recalibrate ... now 530-550.. but numbers seem ok. Then it got higher and higher on subsequent rides, so returned this one and I'm now on another loan wheel with a cycleops joule gps on loan and this seems ok.
So paligap are
thinking that the latest firmware for garmin 500 is pushing the calibration out because its strange to get so many problems. its just a theory for the moment
So I'm wonder if anyone else has experienced this and are there any known issues or anything under investigation?
