Re: Calibration with a DFPM

For what it's worth, I've had much better results just doing a regular iBike calibration procedure without a Powertap, but using double the distance (e.g 4 mile instead of 2 mile cal ride and then 12 x coastdowns). Then I use the Powertap to check the results. On my summer bike I never had to tweak ...

Re: Rain & the Wind Port

Does anyone know if you need to recalibrate at all when using an RWS or will your standard profile be good enough?

Re: Rain & the Wind Port

That rain port example looks quite mild! Here is usually what happens for me once I turn the bike into driving rain. Great idea for a new feature though. I used the missing cadence function for the first time the other day, worked well. For what it's worth though, I've never had any scaling issues o...

Re: Switching profile to the same profile changes result

Coachboyd is right of course. That will fix the tilt problem.

The problem will still reoccur if you send a happen to send the profile from the software back to your iBike again, unless you update the profile stored in the software with the procedure above (or you do another tilt cal).

Re: Water or Low Battery?

I've never really had a problem with water and I live in the UK (aka rain central). Only once did the wind port stop measuring properly and that was a huge downpour. Next day the iBike was fine.

I have a lot more problems with water gettting in the Garmin GSC10 sensor.

Re: Auto Trip Reset: Feature or Failure?

I don't have a strong feeling either way and can see both sides of the argument. It's no big deal to do a trip reset manually, on the other hand 4 hours to me is clearly a different ride. If a menu option was implemented a better idea might be a number between 1 - N hours that you can set for the au...

Re: Can't get to "CAL RIDE" screen

Good point. Also I'd recommend doing more than 3 coastdowns. Half a dozen would be good, a dozen is even better! Also I'd say do your coastdowns and then do the cal ride right away, so the conditions are the same.

Re: Can't get to "CAL RIDE" screen

There isn't one on GenII. You just do a 4 mile out and back ride after your coastdowns. Then select that when you get back to download the coast-downs/cal ride from the menu.

Re: Switching profile to the same profile changes result

No I don't have fine tuning turned on, and the total weight is the same (79.8kg)

The weird thing is, if I pick a ride done a couple of weeks ago with this same profile and switch profile to the same profile, nothing changes. If I do this to last nights ride for example, it was a couple of watts out.

Do you mean trip reset? You need to hold down the centre button until you see "Trip reset" (about 2 secs) when the screen displays this message, press the centre button again to confirm. If you don't do the second press, trip is not reset. After the cal ride the trip is reset anyway, I thi...

Benlane do you mean a CRR of .0200 as you posted, or .0020? I tended to get .0020 (the normal range is usually .0040 to 0090). I've never seen a tilt like that before. Everytime I've had a big positive tilt it's because the tilt is wrong, but I'm using a stem mount. How about you? By the way, in the...

Re: Power meter comparision (iAero vs DFPM) - incredible

There is definitely something wrong with your second profile. Even for a TT bike that CDA is too low, that's what is causing the low numbers. The question is why? Is there any chance the wind port was blocked in your cal ride, do you have the Remote Wind Sensor? For the record, my cal ride with a DF...

I just installed a DFPM (CinQo Saturn), and I had the opposite experience.

I did only the 4-mile ride and no coast-downs, per the instructions as I understood them. We...
