Torque Sensing Pedal Assist for Xiongda 2 speed electric hub?

I have my 48 volt Xiongda 2 speed hub laced to a 26" front hub, on a mountain bike. I am using the Lishui controller and have installed the cadence pedal assist on my crank, along with a thumb throttle. All works well, including my shifting. But I would like to replace my cadence senor with a programmable torque sensor, ideally using the same controller. Xiongda says that none are available, but I would like a second opinion. Is anyone running a Xiongda 2 speed hub with a torque sensing pedal assist?
