Newton+ wigged out on ride(s)
Posted: Sun Oct 07, 2012 4:36 pm
Over the past two days my Newton+ seems to have been behaving a bit strangely.
Yesterday I saw some strange power readings while descending a pretty long and steep descent (approx. 3.25 miles; average slope -10.6%; average speed 36.5; max speed 49). Based on this selection (about 3:33:30 - 3:39:00 in the long ride file) my average speed was shown as 163.8w and max as 743w. That's pretty hard to believe when doing this kind of descent. I also noticed when I was heading for home that I thought I was going into a headwind but the Newton said that it was a tailwind. The ride file has had a "Repair Ride file for Bad Tilt" applied to it, I have not tried to revert to the original file yet to see what the difference might look like. But .. I do have today's file which is even more telling.
On today's file starting between 1:30 - 1:40 you'll see that the wind speed just levels off at about 11mph solid for the remainder of the ride (almost two more hours). I tried stopping on my way home and blowing into the wind port and doing a tilt calibration and wind calibration. On the wind calibration in a calm are the Newton read about 10mph wind consistently, no movement.
I have since come home, downloaded the ride, upgraded my Issac software to the most current version, done a hard reset of the Newton, done a tilt calibration, and then ... tried to do a wind calibration in my closed garage. When I was trying to do the wind calibration I was see a consistent 12 - 12.7mph wind reported. There was no wind, this is a closed garage.
Help ... please ... what's going on here?
Thanks,
Robert
