Re: Tsdz2 firmware open source adapted to vlcd5

to be more precise .. :roll: no error code is shown on the display. it works, lights on, battery state is low (wrong) and flickering and no speed is displayed. and the motor is not working. You need to also flash the stock option byte: https://endless-sphere.com/forums/viewtopic.php?t=93818&start=1...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

Today I did 2 tests: installed the alpha 9 version on the 36v engine, obviously it works great. thank you! Unfortunately the emtb is still bad for me :-( Later I tried to power the 48v bike with a 36v battery. It becomes very quiet, it is still fully usable on the road. I think we are the only ones...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

I guess you also need the bafang extension cable since the supplied one is just 62cm?

Also, I tried eMTB with sensitivity 5 and got max assist of around 350W which was a bit low for some climbs (if I went down to max assist it boosted to 800W+)

Will try sensitivity 7 next to see if it will improve.

Re: Tsdz2 firmware open source adapted to vlcd5

How do I enable eMTB with the display? I'm on assist 3 and hold the i button but no E codes turn on. ( I have XH18 display and set the display and eMTB mode in the configurator)

Re: tsdz2, controller options for open source

All firmwares have basically the same functions, the LCD is only used to communicate with the motor controller (which is the same for all TSDZ2 motors) Yes, STlink is used for programming the LCD and motor. You can get it on ebay for 2-3€. I suggest you read the OSS wiki and the thread and ask quest...

How do you "wipe" before upgrading? I just flashed over 0.19 and it seems to be working okay, had to setup everything again.

Re: New "TSDZ2 Torque Sensor Central Motor"

I'm making a thinner gear cover to get a few more milimeters on the chainline. Prototype is 1mm thick, and the spacers for the chainring are 3.2mm so it's 3.2mm closer. Still need to shave a few tenths off the cover or make the spacers thinner as it rubs a bit. Maybe I can put it around 0.2-0.5mm cl...

Re: Do you *have* to use a MTB for fitting a TSDZ2?

Ofcourse not, that bike will do just fine. Just make sure the bottom bracket is suitable for a TSDZ2 (68/73mm width, pressfit ones might not be compatible)

Check the open source firmware for the motor, more control over parameters and better battery control.

Problem with sending to UK is the battery, thats why only Mainland Europa.
Pitures are coming but it is the BBS02 lates version. Absolutly silence.
Use Eurosender/GLS, had no problem shipping 48V 20Ah from mainland to UK.

Re: New "TSDZ2 Torque Sensor Central Motor"

The Open Source Firmware helps with the blue gear, because it has a 5A per second ramp up, so it is better in this case than the stock firmware. The blue gear will last a lot longer. Awesome! Thanks a lot! I am going to try the new firmware as soon as I get my hands on the required components. Actu...

Re: New "TSDZ2 Torque Sensor Central Motor"

When i stop pedalling, the motor still spins for a 1-2 seconds. Is that normal? Is it related to the beta 2? Maybe it is something that was fixed in beta8 or should i downgrade to v0.18.2? Same on beta 8. Didn't use 0.18.x versions so don't know if those also have the issue, might try downgrading.
