Wahoo trainers with Virtual Shifting Issue: "Free Watts" | October 2024

Hey everyone - Wahoo has released a firmware update on KICKR v6, KICKR CORE, and KICKR MOVE that should address this issue.

Please update using the Wahoo app at your earliest convenience.

UPDATE October 29 - Wahoo has updated their firmware release note pages linked above with this information. Please note the difference between auto-calibration and factory spindown in the context of immediate resolution.

  • Fixed: Auto-spindown errors when using virtual shifting in specific scenarios.
    • In the previous firmware versions, there was an issue with the trainer calculating the correct spindown values during the auto calibration process in certain scenarios when also using Zwift Virtual Shifting. The conditions could result in the trainer reporting “ghost” watts (watts while coasting), and could result in a power offset throughout the ride. If you are currently experiencing “ghost” watts, this firmware update will not immediately fix the issue on its own, but having updated to the current firmware, the auto calibration process will fix the power offset over time without manual intervention. If you would like to resolve the power offset immediately , you can complete a factory spindown.
