is there a different angle on the sensors ?, might be worth googling ?
have you tried to disconnect the halls completely, then spin the cyclone ( watch fingers) , then throttle...sensorless on the controller works great, but you got to be moving the motor first for about 1 second before it kicks in, with halls not connected.....if they are wrong, you can rule it out by not having the connector plugged in at all....did 200Miles plus recently on an external with no halls connected...purfect
