ERG Mode NOT working after latest Update [1.41] [3.47] [June 2023] [SOLVED]

Same issue here with a Saris H3.


Can you give more information, I have a H3 no issues.

Not much to add, its identical to the issue described above. Everything is paired correctly, workout starts with erg mode enabled but resistance doesnt change. Also, switching to “Incline” and trying to adjust there has no impact. Have tried on several different days, restarting everything, etc etc etc.
Worked last week before I got the update. Pretty clear this is an issue on Zwift’s end.


Completely agree on that.

Any ideas from swift administrators?


Yep same issue with stages bike. Erg is all over the place and not provided enough resistance. Can’t hit targets during workout.

Can’t get that link to open. Anyway short version. Got the sb20 at the start of the month but haven’t used it due to injury. Finally gave it a bit of stab today. I use xert and would normally set up giving my Garmin control and run xert through that. Couldn’t get that working at all today, tried a few different ways of connecting. Eventually gave up and downloaded the workout into the custom folder and connected as normal. Erg mode would not engage. No where near the targets for the intervals and it wouldnt ramp up. Even tried.connecting through the xert ECB app. No idea wots going on?


In relation to this request and the post. Let me provide the requested information:

  • Latest versions of Zwift and Companion App Installed: Checked
  • Operating System on PC is up to date.
  • Zwift official troubleshooting guides read (that was the first thing I did on June 1st)
  • Know issues discuss ERG, but nothing fixed the one I´m experiencing.
  • All equipment is BT connected.

Devices I´m running Swift on:

  • Computer
    • Acer Nitro 5 -AN515-54
    • CPU: Icore i7-975H
    • GPU: Nvidia GForce RXT 2060
    • SSD: 240GB
    • WiFi connected to house internet
    • Operating System: Windows 11 Home 64-bit Version 22H2
    • 16GB RAM
  • Cellphone
    • Samsung A73 5G
    • Updated
  • Trainer
    • Kickr Snap 27CA
    • Firmware Version: 2.3.63 (latest version)
  • Sensors:
    • Wahoo Cadence CB45
    • Firmware Version: 2.0.19 (latest version)
  • Network environment
    • WiFi
    • ISP – Local
    • No adblocking, no firewall software
  • Region
    • Costa Rica, Central América.

Some more pointers:

  • All this started last Thursday just after the latest update on swift game
  • Before that everything was working great
  • All functions seem to be working except ERG (topic discussed here)
  • I reinstalled everything, Swift Game, Swift Companion App, reset the trainer, rebooted phone, tried directed connection with BT to the Trainer, and thru phone as a bridge: result is the same. ERG is dead. No resistance whatsoever in during my regular training.
  • I even redid a train I took on Wednesday (when everything was working fine), and now ERG is dead.

Finally, I just tried everything again today, and the results are the same except for one thing: ERG continues to be dead (it does not adapt the resistance to what the game says), but when I stop pedaling the ERG gets disabled (as it is supposed to) and the trainer goes to SIM mode. Then, when I resume pedaling, the ERG kicks in again, but the resistance gets super hard (I might calculate 300-400 watts), when on screen it should be 75wts (for example).

Hope this helps some way….

Does ERG work on other apps?

It does.

Just tried on native Wahoo App, and it works perfectly.

I actually tried it and uninstalled the wahoo app, to make sure it was not interfering with SCApp, and same result.

Do you have a ant+ dongle to try.

I´m afraid I don´t have one.

Does the trainer change resistance on a free ride.

I just did.

I tried a free ride on Hilly Route to make sure there were hills and gradient, but no change. Pretty much my wattage is still the same, but the speed decreased a lot (as expected). So I guess that´s working fine, since the trainer recognizes my change of power and adjusts the wattage and speed. The resistance would need to be created by switching gears.

Two pictures seconds apart:

First one at 75 watts

Then second one at 123 watts (notice the change in KPH). 30 seconds difference with the first one.

One more of the in-game

What do you think?

That is not right, when you approach a hill it should get harder especially on a 7% incline.

Sorry more questions.

Can you check that the trainer is not connected to the phone or Pc’s bluetooth, if you see it in the bluetooth devices you need to let the device forget it. Bluetooth can be very tricky.

Thanks for the screenshots. Do you have one of the pairing screen.

Hmmm I might think that when the route gets steeper, if I don´t increase wattage, then the speed should decrease… :thinking:

The trainer is definitely not connected to any other device. I even erased the Wahoo app to make sure of that. I checked the computer and cellphone and it is not directly connected to them, it only connects thru the SC app.

If you mean, the pairing screen in Swift Game, here it is:

I already tried connecting thru Bluetooth from PC and it´s the same thing.

Here´s a pic of how it looks on the app:

Thanks for all the help. I´m this close :pinching_hand: to just give up… I tried everything.

I even contacted official Swift Support and they gave me a procedure to uninstall the Game altogether and reinstall it. Just did it… no success. I just don´t know, and I swear, none of this was happening last Wednesday before the update.

Thanks again for your patient assitance.

Two things should happen - speed decreasing is one of them but the other thing is the resistance the trainer is providing should noticeably increase. E.g. if you close your eyes and ride just before a hill, you should feel the hill just the same as in real life, and the pedals should be much harder to turn. This second aspect is what the other user was asking about - to try and see if it was just workouts or also free riding affecting resistance.

Have you updated your trainer firmware?
After the last upgrade, Zwift stopped sending gradients to my trainer and I needed to update the firmware in the Wahoo app (have a Kickr Core).
