value too low in depict of new firmware 3.5 and new battery doors

RunningZap
Hi

Middle of June, I gave my vector 3 pedals to my dealer due to the huge quantity of problems well known on this forum.

Last Saturday I got them back via TNT without the original box and its accessories when I bought these pedals (I stay polite, I don't use another term for this alpha product).

So I made a test last Sunday morning at Lonchamp, very famous place at Paris and first outcomes after a long waiting period: values seem really too low! i.e. average power around 180 and 220w for an average speed of 42Km/h for a rider of 82Kg lol and I was not sucking wheels lol

If a nice guy could kindly analyse the fit file in attached file, many thanks in advance! At the first view, values from the right pedal seem to be low....

Initially Garmin Support should have replaced my pedals by a new set, but they just replaced the battery doors and made a firmware update...

1000€ thrown off the window, I'm very very disappointed by a such a product. I was wavering to buy another power meter and now I'm wondering why I was so trusting garmin!!!

Have a good day

    How did you connect your Vector 3 to Edge/Fenix/?

    with Bluetooth or ANT+ or you use both?

    Hmm, then i have no idea, my ones made problems with Bluetooth, since i deactivated the BLT on Edge i haven't any probs!

    It looks like maybe you did not do a manual zero calibration (from your bike computer)? This is always a good idea, and especially after installing the pedals, the zero offset may require a few hard efforts (short sprints) to achieve the correct value. The auto zero function will not make large changes such as might occur when you first install the pedals.

    t-smit

    it was the first thing that I made, I reset the angle through my edge menu just after tightened the pedals on the bike and made a manual calibration twice (one after tightening and just before starting my workout). FYI auto zero is also ON as for dynamic data

    If this was the first ride after you installed the pedals, then you will probably need to do another manual zero calibration now that you have done a ride on the bike. The "auto zero" will only do a zero calibration at the end of a ride or right at the start, when the bike is stationary. It cannot do a zero calibration while the bike is moving or while you have your feet on the pedals.

    Before leaving Longchamp, I made a break for discussing with my friends and as usual, I made a manual calibration....

    Garmin is claiming an accuracy of 1% without a torque wrench, so if customers have to make lot of manipulations before riding in order to get decent data... Garmin must review its copy before selling a product, and not a prototype.

    Tomorrow, I bring to my dealer the pedals for a replacement for a new set or change to another reliable power sensor even if I have to put money on the table which is better to have spent 1000€ for a joke!

    Vector 3 has substantially less sensitivity to installation torque than Vector 1 or 2. But they still require the spindles to be installed at a proper tightness that is consistent with normal practice for pedals. Most crank and pedal manufacturers specify 34 to 40 N-m; the only one that I'm aware of that specifies significantly less is THM for their carbon Clavicula cranks, at 20 N-m (max).

    Considering that the pedal spindle is a cantilevered joint that is subject to cyclic precessing forces, I would suggest that 20 N-m is a minimum reasonable value to use. It is strongly recommended to use 34 to 40 N-m (25 to 30 foot-pounds) if your crankset allows it.

    Last try today, last chance

    I reset again the angle through the Edge menu item, short try this morning while commuting: first feeling: values seems either too low or too high when chill-riding. However values seem correct when I actually make an effort.

    This evening, I'll make a workout with climbs... I'll see if the pedals are consistent or not!
