Been using a Kickr Snap for the past 2.5 years but ever since the last firmware upgrade the power has been way off compared to both my powertap and power2max. I reached out to Wahoo but got no support besides initially suggesting my problems were user error and upon providing more data, the response that it's properly calibrated.
I did a test riding at the same speed, same gear, and increasing power in steps of 10W in 3 minute intervals, and comparing the average values between Kickr and Powertap. See results below - the data starts after a 10 minute warmup period was already done.
Per Wahoo, the kickr is properly calibrated which I guess means in their opinion 'good enough'. For me, this is not good enough; when using for example Zwift it will overestimate my power significantly making it too inaccurate. Plus (and even more importantly) when I just want to do a workout in erg mode, I need to take wild guesses to hope to end up with a power where I want it to be. The higher the power, the more the Snap is off, hence training FTP or VO2 max level becomes very difficult. So, are there any suggestions or tricks I can do to maximize the functionality of my Snap? I still need a trainer that I can rely on and if I can't do it the way it's intended, what can I do to improve the functionality? And secondly - is the level of inaccuracy something that is acceptable, or should be expected? Part of my issue is that I had much higher accuracy up until the latest firmware upgrade.
Note that Wahoo 'offered' for me to send it back at my cost, so they could look at it and return it (at my cost) but given the fact that their response already was that the Snap is properly calibrated I don't expect I will actually be helped much.
Thanks for the suggestions and feedback!
