Tacx flux 2 power surge

Wondering has anyone found a fix to power surges on flux 2 trainer ?
Seems to happen mostly with increase in cadence , quite annoying and embarrassing as is basically a cheat.

any help appreciated.

Used to have this issue, but haven’t seen it once I updated to the latest F/W about 2 years ago.

Still, I’ve seen Zwifters post about this issue even after having applied the update.

Yep have seen similar where issues has been resolved with update, unfortunately mine is running latest software and still no difference.

I have the flux 2 and have had great luck for almost two months.

last night, my resistance keep surging and the rpms would drop down to the 20’s even though i was steady pace in the 80’s.

This was off and on for my full 35 minute ride.

i am up to date on firmware, but was very annoying.
