At 2 turns the trainer seems to work fine after calibration in both Rouvy and Golden Cheetah. Right now my wife can calibrate the trainer if she only puts 2 turns on the knob. I've been trading emails with product support all afternoon. '.the street finds its own uses for things' The reported coast down time was 3.32 seconds, BTW. I have an FTP of 265 watts and nearly 400 watts for 30 seconds, followed with a steady decrease to about 180 watts over the next 2 minutes was a bit of a challenge for me. If this happened to someone with a FTP much lower than mine they would be screwed. I ran the firmware update the night I put it together and it was up to date. The tire is at 120 psi and the tension is set until it ratchets, just like DCRainmaker suggests on his site. It would seem that the trainer shipped with it's calibration way off. TSS is the same, so the calibration fixed the problem and I assume the next time she runs the calibration she will be able to do it.
Now that I calibrated the trainer her power between the C1 and the trainer are within a few watts. Her power in Rouvy was much lower than the power in Garmin Connect before the calibration, but she didn't notice because she was so mesmerized by the video that was running - Her only trainer software to that point was Golden Cheetah. She has been riding in 'race' mode so the trainer was just setting a resistance and not a power target.
