I have an issue with the workout FTP Test (Short). Once I need to hit 220+ wattage intervals, the measured power decreases even when I go faster in the same gear. If i measure my watt-output with the tacx utility app than I easily measure 250+ watt.
I’m using a Tacx Vortex and the IOs app. Pairing all goes well. Climbing mountings on the ‘just ride’ option also works fine.
I have upgraded the tacx firmware to the newest version. I have switched the tacx on and off for multiple times. I also did that for the blue-tooth pairing.
Can somebody tell me what I can try to fix this?
