My brand new Tacx Flux 2 trainer is updated to the latest firmware and successfully calibrated using the Tacx app but Zwift spin down calibration will constantly fail.
I am not sure if this is related but I also have the feeling that the “inertia” of the trainer when riding on Zwift is not realistic. When I stop pedaling the speed decreases at a much faster rate than it would in the reality, or at least that is what I feel.
Also, the Erg Mode does not work properly when training with intervals. It is very slow to kick in when moving from low to high power intervals and vice versa.
Sometimes I have to stop pedaling completely to make it adapt to the new required power range or else I have to shift gear which obviously defeats its very purpose…
This seems like a technical issue that will require more investigating. If you could please submit a support ticket to us, we’ll be glad to look into this.
After a few exchanges with Zwift Customer Care there was no solution other than doing the calibration of the trainer using its own app, not via zwift.
Also, no solution for the ERG mode which I gave up using.
Hoping it turned out well. If you need additional help, please let us know.
