Hi! I just bought a new Flux S. I had aTacx Vortex and was working fine. Vortex was connected to Zwift in Windows 10 with Giant cadence sensor and Tacx heart rate monitor. All connected via bluetooth. No issue.
The Flux S not so much. In normal ridding mode, it’s fine. But In training mode, ERG doesn’t work at all. It’s like ERG is off all the time. New firmware. Reinstalled Zwift. Nothing works. Zwift cannot lock wattage.
I don’t have an ANT+ dongle. So no chance to try with ANT+.
I use a new Tacx Flux S with PC and ANT+. Sometime i use also the HandyApp and my PC at the same time. When i ride “normal” it works.
I did a ramp test, because the watts should be limited in erg mode, i.e. 160, 180, 200 etc., but it doesn’t work.
So far I removed my Giant cadence sensor and use only the Tacx for power, resistance and cadence in Bluetooth. The ERG mode works partially. See examples:
ERG 140W, If I pushed hard (175W), trainer won’t adjust resistance, it can’t
-ERG 140W, If I slow down smaller cassette ring(125W), trainer will adjust resistance to maintain 140W
-ERG 200W, If I pushed hard (245W), trainer will adjust resistance to maintain 200W
-ERG 200W, If I slow down (175W), trainer will adjust resistance to maintain 200W
All this testing been done with only power and resistance in bluetooth from Tacx trainer.
now i am connected with FE-C. Yesterday i have done an Workout with 1 minute 120W and 20sek 240W. I used the same gear without shifting and it works. So i think thats it.
You have help me so much, many many thanks.
One Question - Team ODZ?
Watopia_Wayfinder?
Gerrie, a good time on your bike, many thanks and “ride on”
Hello, I am having the same issue. I have the Flux S and on Zwift it says that the power source and Controllable are connected to bluetooth but watts stays on 0. Please help.
I have the original issue. Tacx flux S, MacBook air, connecting with fe-c or any other option including bt does not engage erg. Simulates normal rides ok. Any ideas? Latest fw on trainer. I’ll try with iPhone today but that is not ideal in the long run
Hi All - I’m have a similar issue with ERG Mode…
Relative newbie…Recently bought a TacX Flux S and have been able to connect ok (using bluetooth to my windows 10 laptop).
Power, cadence, controller seem fine for the most part (apart from occasional drop outs), but when I use Zwift Training with ERG Mode On the resistance control seems to repeatedly fail.
This leads to being told I’m spinning too fast if i try to match the prescribed power, or to reduce power if I try to match the prescribed cadence.
I thought the beauty of ERG Mode is that you can just concentrate on the work, and not the shifting etc.
It has worked occasionally, but for no apparent reason seems to fail lots.
I’ve tried disconnecting, restarting everything (laptop, trainer, Zwift etc…), and switching ERG off and back on again during the training session, but no dice…
…vvery frustrating
On a side note I cant seem to perform a spindown through Zwift either… works fine with the Tacx App, but with zwift fails to connect…
