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

Has anyone had a difficult time finding working LM35s for the temperature sensor? I've bought 2 lots of 10 from different vendors and I can't get it to work on the open source software. The bike just doesn't register any change from the sensor. I guess part of the problem is that they're from ebay ...

Re: New "TSDZ2 Torque Sensor Central Motor"

You have the fc-e6000 installed on an older model and they're fine? Mine is from this year so I guess the spindles are shorter. Would you mind posting a picture to show the size of the gap between the crank and the bottom bracket?

Re: New "TSDZ2 Torque Sensor Central Motor"

Anyone tried using Shimano Steps FC-E6000 crank arms? I tried 175mm and when I tighten they are not moving freely. Original crank arms fit well. I have 73mm bottom bracket. Thanks. Yeah I just ran into the same issue, the holes are bigger than the stock crank arms so instead of leaving an air gap b...

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

So I was messing with the max current of the battery and it let me keep going past 18 Amps even though the documentation says it should be limited to 18. This is on 0.19.x. Can anyone double check if this is the case for them or if maybe my install is funky and I should try reflashing the lcd. For ...

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

The current does spike up to around 12 when I first start pedaling from a standstill, along with the wattage, but it quickly stabilizes around 400w @ ~8 A. I tried reducing the battery resistance but I think 130 milliohms is about right. The 48v high cadence mode seems to lower the duty-cycle, as it...

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

My motor is 48v, I actually just installed a temperature sensor last weekend and I didn't see any damage like the burnt looking coils you show on the wiki or any water but I can check again to see if anything is wrong. How would I be able to verify motor damage from visual inspection? If everything ...

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

Sorry could you clarify, do you mean increase or decrease the gear ratio? I'm currently at the highest rear gear my bike has unfortunately. The front gear is a 52T single gear. Is the intent to try and get the motor to spin slower?

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

From a quick test I got:
PWM duty cycle : 254
ERPs : Fluctuated between 390-400
Also, current seems to max out around 8 Amps seated, I can get it to jump to around 12 if I start pedaling standing.

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

Hi, First I wanted to say that this project is great, I've been using the software and overall I enjoy it! However I've noticed that the assist levels seem to hit a wall pretty quickly, at least for me. I'm actually finding that compared to the stock software I'm around 10% slower at max speed and t...
