With auto throttle on, engine 2 still responds to joystick throttle lever 2. Throttle 1 has does not react to the joystick (as intended ?). Moving the joystick levers then creates an asymmetry in  throttle positions that is not recovered by the auto throttle.
It is as if the auto throttle only disregards joystick throttle lever 1 when engaged. 
Input is done via fsuipc as normal FS axis. 
Thanks.
