first of all, I recently switched from Wahoo KickR 2018 to Tacx Neo2T. With the KickR I had a consistent power output while riding on Zwift. Power was always accurate between ±5 watts in ERG mode.
The Neo 2T swings between ±20-30 watts. e.g. riding 230 watts in ERG results in shown values between 200 and 260 watts. Even with 3s smoothing.
My setup is running via BT on an iPad Pro 12 inch, latest iOS 13.5.
Cadence and control is done by the Neo, no other devices are paired, only my HR sensor.
As I already read that BT needs the correct weight I set it with the Tacx app. Also the latest Neo Firmware is installed.
Maybe its because I am running oval chainrings, but I never expected any problems with them using the KickR.I know that there are similar issues using a crankset based powermeter with oval chainrings to measure power instead of letting the trainer measure it, but the crankset isn’t paired to the app or anything else that has impact on zwift.
Is there any known issue like this? Or is there a fix for it?
I believe(!) that this behavior [messes]* up my training, as it feels much harder riding the workouts since I switched to the Neo. Maybe because the trainer tries permanently readjust the intensity of the intervall, or so.
