I've solved the boost delay issue by running my own custom motor firmware. Give it a try https://github.com/r0mko/TSDZ2-Smart-EBike/releases/tag/v0.57.13

You can remove the sprag clutch using a gas torch, a mallet and ice cubes. Just heat up the gear together with the old sprag clutch, then apply ice cubes to the bearing and give it a kick with a mallet from the behind of the gear. It comes off easily. To install a new sprag clutch you heat up...

Apparently there were two reasons of the ridiculous noise. Firstly, gap between gear and motor housing is too small, and the gear was rubbing the motor case. One washer wasn't enough so I put two, and then the grinding noise gone, but gear whine sound remained unacceptably loud and rattly. The...

I've installed a brass replacement gear to my TSDZ2 and oh man it sounds just awful. I've not expected it to be so ridiculously loud. I thought that it will make the whining sound louder, but in fact it hasn't changed. It makes grinding or rubbing noise so all the people nearby turn their heads...

Congratulations! If you want some more low-end response, give it a try: https://github.com/r0mko/TSDZ2-Smart-EBike/releases/tag/v0.57.13 This is an alternative firmware for TSDZ2 that works with v0.8.0 display firmware, but uses another algorithm to calculate current. It gives you a lot more...

Yesterday I gave it a try with rotor offset value of 7. With this value the assist behaves fine and consistent throughout the cadence range, but my battery depleted very fast and the motor became crazy hot in no time at high RPM (80-83 RPM cadence). I even caught a complete shutdown at 85° after...

I'm using MacOS for everything except for flashing FW with bootlater into 850C.

First I tried 5 and got very substantial increase of low-end torque, but very weak assist at high RPM. I decided to go further and set value to 0, but got very high current and weak assist at any RPM. The sound of the motor has also changed, it became louder. Then I set it to 7, this value gave...

Why not buy a XH18?

Calling ebike_app_controller twice as often as before. if((ui16_TIM3_counter - ui16_ebike_app_controller_counter) > 50) // every 50ms I'm not sure whether it broken something important related to time/power calculation/etc. But it feels as noticeably reduced lag between applying force on pedals...

I spent a day tinkering with the code to cope with jerks and bucking from the motor. As I'm pretty happy with the result, I've posted a new release for low-end torque fans. Here it is: https://github.com/r0mko/TSDZ2-Smart-EBike/releases/tag/v0.57.12 What was done: Made overall response faster...

You can try out my mod then before switching back to stock firmware. It has much more acceleration at low RPM. Give it a try: https://github.com/r0mko/TSDZ2-Smart-EBike/releases/tag/v0.57.10 and the older version: https://github.com/r0mko/TSDZ2-Smart-EBike/releases/tag/v0.56-experimental

What made you switch back to stock firmware?

Apparently we're talking about the same problem. My torque sensor appears to be quite uniform. I will try to enter average values tomorrow and will also try to tinker with COASTER_BRAKE_TORQUE_THRESHOLD.

Force of butt-kick definitely depends on assist ratio. Also after applying torque calibration it became much milder, now it is not even a kick, but a gentle push. But anyway it kinda bothers me. It happens when you briefly stop pedalling around the point, when pedals are vertical. The motor...
