Resistance problem with my Flux 2 Tacx when on Zwift

Hi everyone,

Resistance is changing 1 race on 3 when I use Zwift with my Flux 2 on a Mac. Most of the time resistance didn’t change. I tried with the Tacx application and Sufferfest to see if trainer problem or Zwift problem, and other application works perfectly.

Any suggestion?

I am on ERG mode
I bought the ANT to try to solve the problem, nothing change.
Thanks!

+1. I have the same problem. Brand new Flux 2 latest FW. Everything is fine in other apps but it seems to not be that controlable when riding in zwift.

Did you pair it as controllable FE-C and as a power source.

Yes. It does apply some resistance but it seems to stop during a hill and then it seems to fluctuate a lot. During my last ride it began to apply resistance on downhill

Same here, latest firmware. no resistance, either manually setting the incline or in ERG mode. no change at all.

My problem was solve by disabled bluetooth and works with ANT+ and FEC device. Contact zwift!
