Calibration ride--need to do anything special?

[eschlange]

Do I need to do anything special during calibration (ride on flat ground, don't use brakes, etc)? Or can I just ride like normal, wherever I want?

Just ride normally, wherever you want!

My Powerpod is due to arrive Monday. Looking forward to it. I have both Chip Seal roads and Smooth Asphalt roads here in NE Ohio. There is a great difference in rolling resistance. Should I calibrate on on or the other, my normal rides could have both. How would the Powerpod know the difference? Thanks

For starters just leave everything as-is. The default settings should work reasonably well for both surfaces.

Hi,

I've just received my powerpod.
The only thing i have set in Isaac is my weight, and i'm ready to ride.
But i'm wondering if it is ok to start with a "big climb" : my first ride is supposed to be at the moutain, starting with 9km / 7%. I'm not sure it's the better way to calibrate the powerpod. Perhaps should I do a 5 / 10 min flat ride first ?

Thanks a lot for your answer !

The first 5 minutes of your first ride, the PowerPod will calibrate itself. Then, you're all set!

Set up my PowerPod for Trainer and numbers line up good with my Kinetic In-ride, which I will now sell.
For outdoor riding, I see in the ISSAC Manual V3.0 there is a Check calibration feature that involves an out and back ride. Can that feature be used with the PowerPod? I understand the manual was written prior to the PowerPod.

You can do an out-and-back ride if you wish, then post it here for comparison.

If your PP is like everyone else's then there won't be many corrections to be made!

Attached an out and back ride. Not sure how to do the check in Issac. The manual seems to use a lot of Newton references. I notice my power reading occasionally drops out to a dashed line. I have replaced the batteries in head unit and sensor. Magnets close and my speed/cadence never drops out on head unit. I am connecting to a RFLKT+ with the wahoo speed/cadence sensor on rear wheel/left crank. Powerpod mounted on right handlebar, clear in front with Aero bars in front but above. Any advice is appreciated!
Thank You.

In the ride file you posted everything looks great.

You did a nice job of the out-and-back ride; it is obvious from the symmetry of the elevation profile.

Do the following:

1) Connect your PowerPod to Isaac

2) Open your out-and-back file

3) Select the Analyze/Check Calibration...feature

4) You'll see that you can achieve a moderate level of improvement. Wind scaling of 1.5 (don't know how that got there...) will be updated to 1.410 (Factory Default is 1.40)

5) Click the "Send Profile to iBike" button, and you will be all set!

Thanks for this additional information. What is the best duration for an out-and-back ride?

[Velocomp]

Five minutes out and five minutes back is perfect. You can make it longer if you want, but don't make it so long that wind conditions change.

John, thanks for the reply. You are very helpful! I have a few more questions.
1) Is it normal to see a lot of lines to zero when showing power with 0 smoothing?
2) I also notice that if I extract a profile from this ride under edit profiles, it shows the cadence shows an ID but is not enabled.
3) I am not connected to the powerpod right now, but wanted to see the changes. I rode in the drops on Asphalt blend with tubular tires, (Vitoria Zafforo Pro), Premium? This gives me a little bit more change. Is it OK to use these settings?

[Velocomp]

When PP is set to zero filtering you are seeing totally unprocessed data. ANY change in applied or opposing forces, even for a fraction of a bike crank turn, can cause power swings. So, yes, you can see zero power when using 0 filtering. I personally use Dynamic Power Smoothing or, otherwise, 3 second smoothing.

You have a combined speed/cadence sensor, so the IDs are the same. Everything is fine

I don't understand your final question.

Five minutes out and five minutes back is perfect. You can make it longer if you want, but don't make it so long that wind conditions change.

I should add that the 5-min ride should exceed 1 mile. If not, Isaac will not allow you to use that ride for calibration.

I posted in another topic about time for out and back ride, but got answer here.

Just a comment on previous posts, you mentioned the 1.500 wind scaling and don't know how it got there, mine is also set to 1.500 as default, PP on handlebar mount.

I'll do a out and back and see what the difference is.
