There is a new version of the app available 3.4.0 to allow connection with e7000 and a firmware updateYou can change the motor settings via the e-tube phone app. The default setting gives boost the highest power level and the trail setting the lowest, after eco. The explorer mode gives trail a bit more power and boost a bit less power which feels spot on.
There is info on this thread about connecting Bluetooth as the controller unit will prevent it from working initially.
