Important note to everyone How to unlock your TSDZ2 max speed, over the 45 km/h and get higher pedal cadence If you use LCD3 with your TSDZ2 , you can set any speed up to 99km/h unlike on TSDZ2 original LCD that limits to 45km/h. Higher speed also means higher pedals cadence. This may be particular...

Somebody told me there is no speed limit anymore. He told me there is a video but I can´t find it. Maybe eyebyesickle knows how to do it.

I used our improved original firnware + EEPROM file, that I am sharing, both, on github. I am also using LCD3.

I haven't figured out how to make the wire or use the software to edit the firmware though, but I would really like to try a 15s battery and 5ah should give us 10-15 mile range :) I can prepare the EEPROM file for 14 and 15S and put on github. Right now, there I have files for 7S 24V, 10S 36V and 1...

I just tested my 48V battery on the TSDZ2 36V motor (yes, I had to write the EEPROM with the contents of a 48V motor). Seems to me the motor has less torque at startup (as expected) but gives well high speed. On my new MTB ebike, got 45km/h at flat and on a little descend, 50km/h (strange that I did...

Hi all, first post here. I've been running a BBS02 and a 52V luna shark on my Trek 8.4DS since last November, and love it. I was intrigued by the tsdz2 and after reading this entire thread (100 pages as of this writing) I bought a 52v unit from Ebird on amazon. I've got it on the bike now but motor...

Sad to read, that you want to quit this project.... :( I think there's no problem with the Java Tool, it makes the firmware usable for people who don't have computer skills like you or me :-) If there's a bug in the Java Tool, I can fix it easily. But for this we need the feedback of the users. I t...

Commenting a line in ebike_app.c works with OSEC parameter configurator. But I want the slightly higher configurability of the firmware configurator tool. Can I use OSEC configurator and edit config.h then use the .bat file? please post the output of the cmd window, so we can see what's going wrong...

Casainho replied to my query about adding a datalogger: Technically is very easy to implement that with our improved original firmware, because all of that data is already sent to the LCD3 by the serial line. Anyway, I think that best idea is just to connect in parallel to the wire that comes from ...

Just to confirm that TSDZ2 works well with a 24V battery. I will be running the 36V with a 24V battery (until I install a 48V battery) and the EEPROM is this one:

The java tool is not editig the existing config.h but overwrites it with the recent settings in the tool. @casainho: are there new parameters in the config.h since the last update of the java-tool? No and in fact, I now think it is not a good idea that software as it takes much time to update. I pr...

if 42v gives 90 rpm then 63v should give 135rpm right ? Can the motor controller PWM handle this ? Sorry my bad but I couldnt figure out what ERPS's are..... Casainho just to be clear are you saying your firmware only works with throttle ? since I don't have a throttle and don't intend to use one o...

Hey Guys, We are working on a 14S Battery pack and no PAS, wanted to understand how get the controller working in this mode for a 14FET Controller 1000W. Also is there as a way to derate the motor? As in, limit the power output to something like 350W. Go to the source files and read config-example....

Hmm....I downloaded the latest v3 LCD3 firmware (thanks!), flashed successfully, and then made sure to flash my TSDZ2 controller as follows below (I actually edited a value in the eeprom to work with 52V). Same result :( (throttle and brake work, but display is all on (no backlight this time)): doe...

I wish more developers can join because there are a lot of good ideas to try!!

I think you guys should advance with all that different options, and the hardware parts are relatively cheap and easily available and that is a big advantage. Please go, try and sjare the results and we all will win!!

so with the 48v motor i will reach 4000rpm/96rpm with full 13s battery and 2800rpm/68rpm (70%) with empty battery? and with 36v motor i will reach 4000rpm/96rpm with full 13s battery and the same with empty battery? is that correct? I don't know what may be better... But clearly the limitation is t...

Seems like gear ratio is: outside 92/10 Inner wheel: 36/8 So all in all 92/10 36/8 9.2 * 4.5 = 41,4 / 1 ration so 4000rpm / 41.4 = 96rpm cadence Good work, thanks!! And so 96RPM pedal cadence when the motor stops to assist (his max RPM and also 0 current/torque) but since we should count with some ...

Another test, to see the current controller working. Current was limited at about 3 amps and that a value of ADC = 6, as seen on green line. I hit the throttle fast and put it at max value, as we can see, the current jumps almost immediately to the limited value and keeps there, so this means the to...

Here is the motor pedal cadence limits as also motor max speed RPM -- the same should apply to LB or any other motor: Running TSDZ2 at 62.2V It runs without any problems. I would like to test with 53V but my lab power supply max voltage is 62.2V. TSDZ2 max pedal cadence TSDZ2 max recommended RPM is ...

Running TSDZ2 at 62.2V It runs without any problems. I would like to test with 53V but my lab power supply max voltage is 62.2V. TSDZ2 max pedal cadence TSDZ2 max recommended RPM is 4100. I can't say what is the max pedal cadence but it should be easy to calculate if anyone knows what is the gear r...

So, I am developing and testing on a bad quality dual suspension bike. I could not found a good way to place the motor and at start I just let it rotate against the bike frame... and after some testing, it cracked as seen on the picture -- please be warned. Now, I put a metal clamp... you can see th...

Do you have a picture of the inner parts of the tongsheng motor? I think i've seen a teardown picture somewhere and remember TSDZ has a much lower pole count and the motor is smaller in diameter overall. This can explain torque, and a different maximum motor speed(spec is 120rpm). Both 2 different ...
