Recently purchased 2013 Zero S. Downloaded Zero Application to Iphone and able to connect to bike. What I'm not able to do in drive setup is adjust custom max torque (which defaults to 40%) and custom max regen (which defaults to 66%). Can change slider but immediately reverts to default after changing page. Appreciate any information regarding problem. As a follow-up question, is my bike currently operating under these parameters as listed in the drive setup?
