ERG Mode no longer working?

Good afternoon,

I’m sure theres a million and one different threads relating to ERG issues but im unable to find one specific to my issue unfortunately.

Just had a week or so break from TR and for some reason, ERG Mode isnt working at all. I use a Tacx Flux S thats using the latest firmware and ERG is enabled in TR, but its just running as if ERG was off so the power im putting out is dependent on what gear im in or cadence im running at.

Ive had a few drop outs in the past so today ive moved my trainer into a secluded area and turned off any possible signal interruptions but still no luck, can anyone shed some light?


Did you check to ensure you don’t have resistance mode on instead? There is a hotkey to change it that you may have pressed by accident.

Do you have any other programs connected to the trainer that may be fighting for control?

As far as im aware its not connected to any other applications at the time.

It will sync to both Tacx and Tacx Utility if i have them open but i make sure that the only thing open is TR at the time of training.

It might be worth saying that when using ERG mode in Tacx’s own app, it works fine.

I would suggest submitting a ticket to the support team.


Yep, i have done so just waiting on a response. Thanks for your help nontheless.

I have had an issue with my Tacx Flux S as well. The ERG works fine until the last interval big interval like Mount Field or Holt Hill and when the interval ends to cool down it’s still trying to keep me at my tempo wattage. The speed sensor shows a dropout on my after ride upload to Strava and Garmin Connect as well. The firm ware is up to date per my phone app. Other than those few times, the trainer works great.

Try switching to Resistance mode and then back to Erg.

@team_bunty Yeah i’ve tried that and all sorts.

It actually happened a couple of weeks ago momentarily during my final interval and i had to close everything down and resume workout for it to work properly again, however not even that is doing the trick this time round. I hope support can shine some light on the subject. :sweat_smile:

You haven’t mentioned so I assume you’re not using powermatch? That was causing issues for me I think.

That’s a classical sign of a disconnect. Are you using BLE or ANT+? What device are you running TR on?

Using a Samsung galaxy S9, can’t remember if I’ve been using Ant / BT up until now as never had any issues, both are available to connect though so I’ve tried both.

I’m using a WIndows PC with ANT+

In my experience using Win10, BLE has been more stable and free of disconnects. Also using Flux S.
