Just purchased a new power tap pro, built into a open pro rim. I wired the harness myself and went through the manual setting everything up (refresh rate/sample rate/wheel circumference etc). Then i got on the thing and went for a 40 mile ride. The data for that ride was way off, my max wattage was 1999, my average power was around 320 watts (this was a pretty easy endurance ride), so i cant figure out what is wrong with it, when i am not pedaling the wattage is 0 so it doesn't sound like a torque thing. Any tips, or should i just call up power tap tomorrow?
