great teardown and lots of pictures Tongsheng TSDZ8 750W 48V teardown, disassembly
They send their firmware for a minor update (walk assist issues) on the Facebook group TSDZ8, where people of Tongsheng interact with client (like ToSeven do on Discord and here). Seems, they used same controller as TSDZ2 V2.
don't know unless someone confirmed 100%

Looks like it has a horrible Q on the drive side 
Looks like it even has IPM rotor suposedly resulting in higher power and efficiency over wider RPM range.

so chainring is bad quality? or bad offset?
Here somebody tried to replace Brose motor with TSDZ8:

well . it fits fine . but offset is horrible for someone who wants emtb and needs 34t chainring . you can fit motor by either cutting the mount in the frame and/or placing motor lower underneath . but then you lose some ground clearance which is of course not wanted ...

ok i see you got no normal frame, is that maybe also a reason for bad offset ?
nope . new tsdz8 has much fatter main gear with cover and axle hub . see on the photos how far it extends . I'm sure this will have impact in regular bsa frames also

Tongsheng staff have a Facebook group. Here's the firmware update video. You can try searching for the firmware files there:

Thanks for the update - especially after the firmware upgrade, this looks promising.
I put my sticky hands on this miracle... and so...
he is quiet. in 1st gear it delivers up to 300w. display shows voltage and power. the crank is harder than tsdz2, i.e. stiffer. terribly short main harness cable... I had to run it straight to the steering wheel along the lower tube. generally, the cables go straight down in the middle of the engine, so there is no room for mistake when riding over rocks . the power delivery is pleasant... the sensor responds well, i.e. it is quite hard, so you need to push the crank to get 300 watts. in this respect it is good. it doesn't jerk even at maximum power. delivers very smoothly and pleasantly. the display shows power and voltage all the time, so that's a plus
Unfortunately, at the moment it's crap with no spider for 34-36t chainrings ... Well, this main harness is a failure. on a larger bike it will even be too short to go straight. unless there is an extender somewhere in the box but I didn't find it... the display is a pain at night... normally it hurts the eyes... and those cables going straight down...
this base is only a testbed . not my normal ebike
