Hi, how did you setup the trainer? I use the default choices of zwift (power meter, cadence and controllable set to real fec option)
I think i have the same trainer as yours (elite real emotion v1 of 2011, recently updated firmware to b+ version to support standard ant+ with fec), but for me resistence seems to be controlled (strong) only manually when i select a training plan (i.e. i set manually at 600w), and no automatically on hills.
On the contrary, on flat my resistence increases with speed (over 30km/h is quite high)
Thank you,
bye
Gabriele
