Smart Genius Calibration tool

How can I do to have maximum accuracy with my Smart Genius ? Is there a calibration tool avalable for Zwift and this Genius ?


Just calibrate it in Tacx. As long as it is somewhere in the green section of the resistance dusting calibrating, it should be ok. 

You never will get the resistance exact, and unless you have a power meter, you will never know how much it differs from the “true” value (whatever that is - it also varies with the place you measure it). 

Make sure your weight in Zwift is correct - that can make a large difference. 

Thank for the answer.

So I guess that the calibration number is stored somewhere into the motor brake !
