    Hi,

    Has anyone had an issue with a Tacx Flux giving an inaccurate power reading?

    It's reading about 5x higher than true power

    Firmware is up to date.

    Calibrated via Tacx app and Zwift

    Thanks

    I’ve just upgraded from a flux s to a Neo. Never had any issues like that and found it pretty reliable

    I compared both on Friday and the flux consistently read about 10-15 watts higher when compared to my stages, the neo and stages were pretty bang on

    What are you using for your "true power"? All power meters have a margin of error, and depending on where it's measuring v another device can also give explainable differences.

    5x isn't a margin of error though! :D

    I was assuming that was supposed to be 5% to be honest. Which would still be on the high side, but no power meter is 100% accurate. Pedal v hub is going to be a slightly different figure due to drivetrain efficiency (even how clean it is affects this), then add in margin of error.
