Sorry if it's been asked already, but I just got into the PP game.

Does the Power Pilot export data in such a way that my computer (Macbook Air) can pick it up through a wireless ANT+ stick (from a Garmin 310)? Or does one have to use a flash drive?

bump, and to add:

I'm having trouble uploading my power file into PowerAgent. I can get the second-by-second readout in Excel (which isn't really all that helpful), but get an error message when I try to to upload activity data. The message reads
"java.util.concurrent.ExecutionException: java.lang.NumberFormatException: For input string: "TIME""

The only help the manual gives is that the data "can be loaded directly into TraingingPeaks" by using a flash drive.

There has to be an elementary answer, but I wasn't able to find one in a frustrated, hurried search.

What's your feeling now that you have had the PP for a while? I love the heck out of my Rev and ride it like I stole it(kinda did it was a floor model wicked cheap!).

Would you mind running down a couple of pro's and con's from your long term use?

Our team bought 4 of the Revolutions but the problems with the Power Pilot discouraged any of us from purchasing that unit. How is it that wattage is calculated and then displayed on the Power Pilot? Two riders in the same gear at the same cadence are not pushing the same wattage if they weigh different amounts or do I have that wrong?

My guess is it's based on the flywheel's speed. The resistance of the flywheel + fan (which is directly linked to the flywheel) should have a one-to-one correspondence with speed. Rider weight shouldn't matter for the calculation.

I haven't been able to get my PP to work with the HR monitor that came with nor the cadence. I haven't been home long enough to start from scratch, but I'm about ready to just put the Garmin 500 and cadence monitor back on (which did work) and say screw it to the PP.

I think you have it wrong. They are not moving forward or up, so the wattage should be the same. It's like lifting a weight off the ground at a certain speed. It doesn't matter how much you weight, the power required is the same.

I’ve been using the Power Pilot in parallel with a Quarq. After running the spin-down calibration for the Power Pilot, the power reported by the two devices is well correlated.

I've had the PP for about 6 months. I've only used it about 10 times.
My impression is that the head unit lacks polish that we all expect from consumer electronics. Otherwise, the trainer is a dream, A DREAM, to ride. The power data is really nice to have, but I really want to upload it to garmin connect (or any service really) so I can see a graph of it later and send it to my coach.

I should have been clear, sorry. I also have a 310XT, but I've only gotten it to connect to the PP once. Even then, I failed to get the HR strap to work at the same time as the power/cadence/speed sensors. It feels like a very fragile infrastructure: Trainer to PP, PP to Garmin, Garmin to USB stick in my laptop, Laptop to the internet. I have a 10% success rate getting that all to work at the same time.

I know it's not the ideal way to get things to our training logs, but.....

As for you'r success rate, that's unfortunate. I have had a 100% success rate in getting the info from the PP to the 310.

When starting up, make sure that you...(this is my routine)
-Turn the GPS to 'Off'
- Make sure that 'Fitness Equipment is 'Enabled'
- I rest the PP on my aero bars next to the 310 and press the 'Play/Pause' button to wake up the PP. I do this while pedaling. Wait for the Garmin to say 'Fitness Equipment Detected'
- At that point, I press the 'Play/Pause' button again to start the workout. The Garmin detects the start request and begins the timer and data is streaming to the 310 from the PP.

Also, make sure that you don't have the Garmin set to detect a Combo Sensor. I have mine set to Cadence Only

Those are great tips. Thanks!

I have "upgrade PP firmware" on my todo list, and then I'll try your checklist.

Also, if I set Cadence Only, do I not get speed? I see you don't have speed on your activity link, but there is an overall distance output.

Speed is on there. It's just listed as 'Timing'. It's the chart at the top.

Although a small complaint is WHY did they put the light button right next to the stop? There is plenty of room above the screen to have move one of the buttons. I am sure some poeple have hit the stop button instead of the light.

Once I get going on my workouts, I rarely even look at the PP. Everything I need to see is being displayed on my Garmin.

Yes, you have it wrong. The weight of a rider on a stationary trainer is meaningless. All of the resistance is generated by the flywheel fan.

For the Power Pilot, the speed of the flywheel is measured and then combined with a calculation of air density (based on temperature, humidity, and user inputted elevation) the power is very simply calculated from knowing the rotational inertia and aerodynamic properties of the fan. A coast-down calibration procedure is performed to account for varying "fixed losses" (i.e. from belt drive tension, bearing drag, etc.) from unit to unit.

It actually works fairly well IMHO (as compared to a recently calibrated CinQo) :-)

Tom A. Thanks for the great data. I've got a powertap so have not been able to correlate for myself. I was wondering what other users are seeing with their spin down calibrations. My values seem to vary a more than I expected. For example if I do 6 consecutive calibrations I get values ranging from around 142 to 166. Also the variation is random, not increasing or decreasing as the unit warms up. I assume that since the calibration is for a unit's individual resistance it isn't necessary to calibrate before every ride, correct? I have left my correction factor at 155 mid-range for the values it spits out.

As to tigerpaws question re: pros and cons. To me here are some cons, some mentioned in earlier posts in this thread.

1. Data loss. Not often but at least 5-6 times in the 6 months I've been using it ride data was lost. I was hoping the firmware update would correct this but lost ride data just last week. At end of ride data was there, USB drive connected, flashing FAIL message, data gone. I don 't know how many others have this problem but at least two others have reported data loss on this thread. I was streaming the data to a Garmin 310xt for back up but sometime the Garmin doesn't want to connect. As can be seen above linking a Garmin is just one more thing to deal with.

2. Displayed wattage bounces around much more than I'm used to seeing on my powertap. For the last 2 months I have been synching to TrainerRoad which helps me keep a steady effort. Say I'm trying to ride at 200 watts. I find it easy to keep the displayed power on TrainerRoad ( which is also calculating power by reading flywheel speed ) steady at 200 - 205. My data downloaded after the ride shows a good steady output. However the Power Pilot is bouncing around perhaps +/- 20 watts. Since there is no lap or interval average feature to me at least it's difficult to know how well I'm holding the target power.

3. Lack of user interface polish compared to other products. Example, if you go down into a sub menu often you cannot back up but need to wait for the unit to time out and go to sleep.

4. It's starting to look like the ability for users to create workouts isn't going to happen anytime soon.
