Hello Ray, Thanks for the reply, but I didn’t bother asking anyone else. I thought maybe it was just something I was doing wrong. But it’s really off of the bike or not. I can calculate running powers fairly easily with the power meter on the crankset, but when I change altitude or change wind if I have a different gauge on the Computrainer it reads higher than the one on the crankset. I know it’s not some electronic problem, because I was able to figure out how to set my bike with the Computrainer with 3 eBikechamps tune files, but it would always record different than my crankset when I was warmed up, that means it was recording something other than what was on the crankset. I tried that today. I’ll try remembering what I did try. I did forget to question further when it didn’t work when I had standard factory files and no adjustments.
Hello Ray. If you are just getting into this bad boy, put a fresh battery in your Computrainer. That will save your battery life. Also, when you pull your crank arms off, make sure to not take them out of the crank arms by lifting them off the bike. You want to take the power reading, not a measuring device. Once you get the hang of it, you can record your watts and display on the trainer. Best of luck
Hey Ray, thanks for posting your thoughts in a comment. I’m looking to buy my first power meter in mid october. Like you, I think the powermeter is only as good as the wattage display. I’m a little confused that you have a grande force foot in a local shop and a computrainer at home. Both will record your watts, but only one is cheap enough and small enough to take with me when I’m out riding. I’d love to work with a pedal mechanics to calculate my watts, but that will probably be a couple years out. Do you have any suggestions of pedal mechanics that are a) in your area, and b) cheap enough to make a difference in performance? 7211a4ac4a
