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

Today I tried the 0.19beta2 and I found out the following issues: 1. The displayed speed is correct, the passing time is correct, but the basic distance unit of the odometer increases by 0.2 km instead of 0.1 km. Practically it doubles the distance travelled (and the distance left estimation). I wi...

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

I'm not buba or casainho but I answer. Buba released as you say earlier v19 beta and it was only for KTLCD3 and now casainho has released beta version for motor too.

Re: New "TSDZ2 Torque Sensor Central Motor"

I've read that the TSDZ2 motor is very fast on temperature. Therefore, I was wondering if in the summer, with an outside temperature of 25 degrees, it is possible to cycle for a long time (30min) on 35km/h. This on a flat road. Does anyone have experience with this? I drived last summer on 27 °C 52...

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

V0.19.X (BETA) works fine. I tested walk assist and cruise and both of them were working. It was quite difficult to drive because steets were covered with ice and slush. After all it was dangerous.

Re: New "TSDZ2 Torque Sensor Central Motor"

Please take some pics to document the maintenance. Perhaps the mods could make a TSDZ2 maintenance sticky for users to refer to. After riding in a misty weather during autumn and not using it for two months the motor now seems a bit louder and grittier. Probably will have to check the grease level ...

Re: New "TSDZ2 Torque Sensor Central Motor"

Be careful when connecting speed sensor connector on the cable which is coming from the motor. The picture shows that the pins are on the other side and one pin is bent and is not visible. The pins are easily bent. My question is where can I buy a cable that comes from the engine to the speed sensor...

Can anyone tell me how you program the Bafang 850C with the STLink or how you program it. I could not find any guide on actually programming it. Exactly what pins on the STLink connect to which pins on the 850C. Any link would be helpful or a general description with details on the connection. And ...

Could it be problem in 52V and 750W motor for firmware does not work? I don't understand. I have 36 V battery and 250 W motor. I've been commuting now two days, not long trips but v17.0 works very well. And it's so good that I'm not going back to stock firmware. Feels just like I have bought new mo...

Thank's again Rafe, I have been triple check wires and solder again wires. I think I go to buy new dongle from local dealer on monday. It's quite expensive compared to ebay but I don't have to wait.

Now I'm going to watch snooker.

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

Thanks Rafe. My ST-LINK is propably not working. When I try to read tabs the light goes out of device. Is this normal? I have to unplug device and connect again and light comes on. Where you have ordered (working) ST-LINK device? Is there sellers in europe? When order from china it takes ages to come.
