problem with elite turbo smart buin b+

dear all,

i’ve been dealing a problem to calibrate my turbo trainer ELITE SMART TURBO MUIN B+.

if i choose pair by speed sensor, my ride is ~70 mph.

if i choose pair by power sensor, my ride is ~30 W, even if i sprint.


in other words:

setting up by speed, sensor is too high.

setting up by power, sensor is too low.


any tips from someone?
