My Cycleops Magnus trainer will not calibrate in Zwift. As seems to be the case for many people, it will only spin down to 4 mph and then gives me a “calibration failed message.”
About a week ago I had been able to calibrate it, but this weekend it just went haywire. There was no resistance on climbs in free ride mode, but a ton of resistance on flats. I downloaded the new firmware and re-callibrated in Rouvy, but I’m fairly confident it’s still not working right. Resistance is wrong and power numbers are wonky.
Has anyone found a solution to this problem? I’m using Zwift primarily of off season climbing training, so not having resistance is really aggravating.
Bill, I avoid using the calibration in Zwift because of all the isues. I have had no issues with just calibrating with Rouvy before I switch over to Zwift. Note that Rouvy has a cold calibration and a hot calibration. The later is more accurate. I do not calibrate every ride. The bike stays on the trainer all winter and I keep the tire pumped to the same pressure
My experience is the same as David’s. His advice is spot on.
