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

I have a similar problem with Adam. When I press walk assist the display shows 100W but the motor does not move. I also took it out. Without power I can move motor head easy. With power it is fix! Torque sensor diag works ok, also cadence and speed measurement. Just the motor does not move! I can he...

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

I did in last weekend a MTB track with 2000+m altitude level and 56km. I used 620 wh. Ride done with 0.20 beta1. On flat road and medium ascend, power mode works perfect. Good power and better torque. On difficult climb, Emtb mode is king! It has a lot of power and the motor reacts instantly exactly...

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

I did some test with 20beta1. SO far no issues at all. My test configuration is acceleration 80%, modified high cadence mode and torque sensor adjustment to 75. I mainly tested in city traffic power mode but also EMTB on a steep garage ramp from -2 to 0. Power mode seems indeed a bit more torquey a...

Re: New "TSDZ2 Torque Sensor Central Motor"

From what I managed to check, the slack originates from the clutch bearing from main gear. But any feedback is welcome.

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

Hi everyone, I am having some chain noise similar to the one when the shifter is not able to change the gears properly, just it comes from the motor area. I hear it when torque is applied to pedals. I think this is generated because the chain ring has some slack and it moves a bit. I added some smal...

Hello,

I got some slack in the chainring from the motor. Are there any solutions for this?

@casainho, thineight Thank you for quick help as always! I managed to crush the lcd cable between the frame and the motor :(.

Let me share simple and effective heat management improvement for the tsdz2 with silicone thermal conductive pads
Thanks for sharing a very effective and cheap solution!
I used aluminium, but it is very hard to make a good contact with the exterior case.

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

I did some tests today. I kept acceleration to 80 so I am not limited by it and adjusted the torque conversion param from 67 to 75. It seems that the torque range is extended. I managed on startup to get peak of 700w+ on level 3 assist. This is very good news because I feared i will have problems in...

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

Very strong pedaling (ratio 34/40) the engine developed 650-700w. But it wasn't the best, if I pedaled more slowly the engine went 850w and obviously the speed decreased. So even if you ride hard you can't get the most. It is not a sensor problem, however, not even a problem of cadence, simply the ...

Re: Hardware temperature control tsdz2

Nice solution, Andrea104!

I made a similar one from aluminium. The complicated part is how to get good thermal contact with the exterior shield so you can draw the heat to the outside.
How did you did that?

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

Ok. I am almost sure I do not fully comprehend how the new configuration works. This is why I have issues. I have additional questions :) 1. Acceleration - I will surely make this 100%. Is it possible to put more, for example 150 if I want higher acceleration? 2. Assist without pedal rotation - I do...

Did some more tests. I just installed the motor on a new MTB 29". I am testing A7 with the default assistance levels. I tested power mode because I wanted to see improvements form 0.19 first, at the moment only on flat city road. 1. Acceleration . Previously I used 8A/s and was very pleased. Now I a...

Press the POWER button a little longer on the display when you want to start it up. When you have verified that everything works then you can try to build the .ihx from my branch. Start by checking the SDCC version you have installed: sdcc -v Install the 3.9.0 if you have an earlier version. Let me...

Hello, I see that EMTB is raising a lot of debate because different users have different needs. I think it is impossible to please everyone. Adding a menu just for configuring EMTB is not a good idea now due to memory limitation. An idea is to use the EMTB mode as an option used in conjunction with ...

It makes perfect sense! This is why I saw on the LCD only the power blinking on 20 or 30 w.
