Did you get this resolved?
I’ve had a direto for nearly 2 years that I’ve suspected to be reading 10W too high.
It’s taken a while to get to a point where I can prove my suspicions as I’ve had a number of issues with Vector 3 drop outs, and also a ponder that the 3S (which I had initially) was under reading because it was only on the left, my weaker side.
After a few successful readings from vector 3 to compare to the direto using DC Rainmakers analyze tool, I then had the belt break in the direto (I have used it a lot).
Replacement belt and I’ve then had to recalculate the offset, which makes some sense.
I managed to get one ride where the vectors and direto were close enough to be acceptable.
But then it’s gone to at least 10W out to as much as 15% out (290W v 250W).
I then borrowed a mates direto, which was bought from the same shop at the same time as mine, and that is just spot on with my vectors.
Elite have now taken the direto back for repair/replacement via the shop and distributor. Not sure quite yet what the resolution is, but Elite have been helpful throughout and are looking at it.
There is no update to the Direto software in the 2 years that the trainer has been on the market. They indicate that there will be an update before the end of the year now that the Upgrado app is available.
I know this isn’t the same Elite trainer that you have, but I reckon that one Elite smart trainer isn’t going to be massively different to another Elite smart trainer in terms of Elites approach to development and support.
