Hello, so I training with the Assioma Duo linked to a wahoo element computer and using trainerroad with a dongle on my laptop. for some reason the data is the same on some power readings like normalized power, max and average power are all close . But with the Kj of total work is way off anywhere from 10-50%. Today I numbers were 940kj on trainer road and 677kj recorded on my element. I calibrate the pedals on the head unit prior to every workout. Anyone have any experience with this?

Do you have exactly the same FTP in both areas? If not, that is the most common issue leading to discrepancies.

Believe it’s a Wahoo thing / annoyance; [image] Looking for advice on a bike computer Equipment Does anyone using Garmin have mismatches between TSS/power reporting? I’m really happy with my Elemnt with the exception that it overshoots the TSS, kJ, and the short max powers slightly and it triggers my OCD brain

Thanks for the ideas, I am going to try to reset everything, see if that helps

Feels like I just answered a similar question [image] kCals vs kJ - why do they differ so much? Ask a Cycling Coach Podcast This is the correct answer to his specific question Your profile is private so I cannot pull exact numbers from your rides to give you examples - but what you’re seeing is one of the main problems with the Wahoo bike computers - they use your age and heart rate data to calculate calories burned, even in the presence of a power meter What this means for most well trained cyclists is that on an easy recovery ride Wahoo will give you a significantly lower number than something based on your pow…

There’s been lots of issues with the way Wahoo records power. https://www.dcrainmaker.com/2017/03/wahoo-elemnt-bolt-in-depth-review.html#comment-2396539 - see this comment on DC Rainmakers blog. I had a similar issue - Yet another baffling data discrepancy (Bolt / TrainingPeaks) And this - Average power higher than NP - why? The issues all vary slightly but most seem to centre around the problem that the Wahoo has a tendency to record “-” instead of “0” when the power meter isn’t being used, which skews the numbers when entered into training programs. Can you link to your ride on TR?

[image] trpnhntr: Feels like I just answered a similar question kCals vs kJ - why do they differ so much? Ask a Cycling Coach Podcast I think the OP’s question only refers to the difference between Kj on the unit and TR, nothing to do with the “calories” metric.

[trainerroad] [wahoo] so here is a pic of the workout and my wahoo from todays ride. everything looks fine except for the KJ

Googled this and came across this thread - doesn’t seem like there’s an answer or a solution, but it is an issue that some other users have experienced https://groups.google.com/forum/#!topic/wahoo-elemnt-users/8oYYLG2GJSU
