I have bought a new Wahoo Kickr Core 2, pre-installed with a Zwift Cog. However, in Zwift my power readings are not accurate at all. Let’s say I start in “Gear 5”, the wattage starts shortly at around 150watts and drops to like 110watts. When you go a into a higher gear, each time, the resistance at the start goes up quite a bit, and then comes down a lot. I can’t seem to get it to be steady.
I tried looking up firmware updates, but it all seems up to date.
Also, there doesn’t seem to be a spindown option in Zwift or in the Wahoo app for this Wahoo Kickr Core 2..
Please help 
Factory spindown is the only manual calibration possible with a Core 2
