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

Hello, Just some considerations about the street mode. At the moment we have couple of parameters to set on the street mode: power (typically 250W) and speed (typically 25 km/h). The Power cuts precisely at 250w then and does not allow any peak value above that, except some +25W of rounding. We all...

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

I found this drive on aliexpress from the seller EUNORAU which seems to be a respectable one. They offer a TSDZ2 with a 850C display and multicable for brakes. https://nl.aliexpress.com/item/32821670861.html Would this work? Finding the pinout one my own and contributing back to community would not...

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

I did the release of v0.20.0-beta.1, get it here: https://github.com/OpenSource-EBike-firmware/TSDZ2-Smart-EBike/releases/tag/v0.20.0-beta.1 Unfortunately I am not able to test it because I do not have the KT-LCD3 anymore, and, just yesterday at night when I was going for a group ride, my TSDZ2 did...

Upgraded from A4 to A5 without any issues. Bike was directly OK.

walk assist: solved
slight motor power after throttle usage: also solved

Thx for all the work on such a short notice :bigthumb:

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

Yes, I do believe your capacitors are filtering out the signal. :( And I do not want to force you to change the lighting circuit so I am glad that mode 5 is working to your satisfaction! The signal is changing every 100 ms so it is very fast. Especially if there are big capacitors connected. That i...

The lights were not turning ON and OFF automatically: flashing? Or they were but the frequency was slow? ---------------------- EDIT: Have now solved the issue you reported of no assistance but am curious what you think of the lights! Should they flash faster? Are the brakes not enabling a faster f...

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

Hi Buba, just updated from A3 to A4: Update (programming) itself went smooth. Light modes didn't work as expected, but I had to use bike. Strangely there was no assist at all. Luckely the throttle control worked ;-) and this even better than the A3 improved version. Once back home, I checked all set...

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

Upgraded from Alpha 2 to 3 without issues: * cadence>90 => solved * slight backward resistance => solved * lights: didn't play with since I prefer to start always from "lights off". I was wondering if lights eg could could come on when brakes are applied (or flash when lights were already on)? This ...

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

@casainho: I am looking forward to use the 850C display on OSF. Are you having any issue with 850C running our firmware? No, I only started using OSF since 0.19.0 with LCD3, then switched to 0.20.0 and thought that 850C doesn't work yet with 0.20.0. My display is opened, the correct programmer has ...

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

58 (on the road) km's done with 0.20.0 alpha2 (36V motor/battery combination). There is indeed a small backward resistance, it didn't disappear as andrea_104kg mentioned, but it doesn't bother me. When the cadence reaches +-90, then the motor power drops. I then just shift gear. I didn't notice that...

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

Hi Buba, Just installed the 0.20.0 alfa2 and it went smooth. I noticed that start riding is even much better than before. What is for me not so clear is if 2: "Power Assist" 3: "Torque Assist" 4: "Cadence Assist" can all be set together. I assume that only one can be set and that in combination with...

I got 0.19 finally up and running 8) by Rydon » This is the same as Bafang display wiring. Your motor probably has a female 8 pin connector and your daughter's has an 8 pin male or a 6 pin female. If your daughters motor has an 8 pin male you can convert her motor to be compatible with this same wir...

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

Hi, I am newby on this forum and I follow this topic silently for a very long time. I installed a first TSDZ2 + XH18 on my daughters bike (still standard fw). I loved it directly and bought a second set to rebuild my bike from to hub motor with pas sensor to TSDZ2 + P850C display and brake sensors (...
