Some further precisions about this video: - Thank you for the warnings about the temperature! It might be bacause of the 36V variant, but so far my 500W TSDZ2 does not heat more than my 500W BBS02B. Of course, if you play with the 48V variant, you use batteries with higher voltage or you push the settings even higher than this, yeah you should be careful about heating - All that you need to know about the values displayed at startup and at lights on is in the Parameter configurator guide PDF, at the paragraph called "Display advanced settings"; for your convenience, here is a list of my custom parameters: ----- BEGIN CUSTOM SETTINGS ----- My motor is a 36V one -> Default_Settings_36V.ini BASIC SETTINGS - Battery power max (W) -> 560 [rev.002] - Battery capacity (Wh) -> 560 [rev.001] - Battery voltage cut off (V) -> 31 [rev.001] - Wheel circumference (mm) -> 26-inch wheel = 2050 mm - Lights -> Unchecked (I don't have motor-connected lights) - Brake sensor -> Checked (I have at least one installed, Throttle ADC function will be available) - Optional ADC function -> Throttle (I have the throttle installed) - Street mode enabled on startup -> Unchecked (I want the full experience at startup) - Odometer compensation -> Checked [rev.001] - Set max speed from display -> Checked ASSISTANCE SETTINGS - Power assist mode -> 80, 140, 300, 450 [rev.001] - Torque assist mode -> 50, 100, 150, 200 [rev.001] - Hybrid assist mode -> Enabled on startup ADVANCED SETTINGS - Time to displayed data 1 -> 30 [rev.002] - Time to displayed data 2 -> 30 [rev.002] - Number of data displayed at lights on -> 2 [rev.002] - Time to menu items -> 30 [rev.002] - Data displayed on startup -> Volts [rev.002] - Soc % calculation -> Volts [rev.002] - Throttle assist value min, max -> 50, 255 ----- END CUSTOM SETTINGS ----- Happy tuning! 💪😎

Hi Luke, I have the BBSHD and the BBSO2B, and with the eggridder, I can set up both motors from my phone even when I'm out riding my bike and through bluetooth I can change the amount of power I want from each pedal assist even switch between off road and road settings with a press of a button.

Hi. I consider to use a Tongsheng TSDZ2b on a recumbent bicycle (HP Velotechnik Speedmachine). The frontwheel has a diameter of 20 inches (backwheel 26 inches). Is the velocity sensor also compatible with a 20 inch wheel? This would save me from considerable extra wiring on the bike.

Hi Luke, if you are looking for a "ghost pedaling" feature it should provide a "cruise mode". You can also change the mode via the display (no need to reload the configuration via java configurator). However, when I tested the "cruise mode", it behaved a bit strange. The bike accelerated to the set speed when pedaling, but then slowed down, then accelerated again... It just wasn't a smooth ride, but a constant acceleration and deceleration. Perhaps this could be tweaked by setting some parameter, but I haven't figured out which one yet (maybe tweak the percentages for motor acceleration and decelaration, so far I'm using the default setting of 35%).

thanks man! I'll give it a try

Hello Luke it is great to use your software on the tsdz2 motor. In fact it easy to install it. It worked perfect. NO errors. And now it is very adaptive. But one thing. Changing the settings with a VLCD6 display is very hard. For me almost impossible. MAybe you can make a short video of it. Thanks and I hope you can give more support to change the settings with the display.

How much did the kit cost? Motor + battery?

I've been running the TSDZ2 on open source firmware for over a year now, just passed 2000 miles. Around 700 miles was towing 60kg in hilly terrain. Feel free to ask me anything specific from my experience. Great video btw. :)

Thanks for your help and video. Can i get some results if will use Android speeed configuration tool ? It's look easy.

Hello I’m from Montreal and I have 2 bikes with the tsdz2b is it worth doing the open firmware? I would keep the same displays… Thanks Any input would be appreciated… Don’t know where to start

When I start with OSF/embrusa using his settings file, there is not much difference in power between stock and OSF in power assist mode, but a little more in hybrid mode and EmtB mode. STill about 60% of the power of my 25A BBS02B, I see you have really increased the assist numbers on the Power assist. Those are usually 50/100/180/280 and yours are 80/140/300/450. Quite high.

Yes indeed. As I say in the video, the goal was to reproduce a closer experience to the BBS02B 500W motor. Of course, I'm not saying everyone should apply those numbers! With them also come more energy consumption and lower motor lifetime. Still, those settings sepresents the most I could squeeze without any thermal or mechanical issue, so I still feel confident with em

Hi Luke, did you try to revert to the original factory firmware after you flash custom firmware? What happens to the odometer after flash the custom firmware? Does the odometer reset or does the original value remain?

@LukeLorusso

Hi, that's a great question! Yes I did revert to the original firmware and then also reinstalled the OSF: in both cases the odometer survived the flash. Which makes me question where exactly the odometer value is stored... maybe in the display itself? Maybe in an unaccessible area of the controller? Not sure...

Ciao Luke, volevo chiederti se questo firmware si può installare anche sul TSDZ2B. Grazie

This may be a dumb question. When you upgrade the firmware, will you have to upgrade the firmware again if you change your display?

@LukeLorusso

it depends on the display: this OSF version is specific for the VLCD5 stock display. So if you'd like to install the modified 860c display afterword, yes there's a different firmware: you first need to restore the stock one and then install the specific OSF version for that display

Hi Luke. since I am ready to choose which Tengsheng variant of motor to buy could you pls help me in this choice? I saw that I have the chance to buy the 250W 36V, the 350 W 36V, the 500W 36V + the 48V that i dont mention. Consider that I dont care much about the legal problem because I rarely bike in normal roads and mostly I go on hiking paths and mountain roads. of course the 250W will give me less but probably will use more battery than the 500W. but the 250W can be enough? or i cannot compare to Bosh, Brose and other motors and maybe it's better to get the 500w? Grazie

Hey Giorgio! Those variants of the Tongsheng you mentioned are all 36V. Which means, they all deffer each other by software configuration. If you intend to install the OSF, it doesn't matter if it's the 250, 350 or 500W: it's simply the same motor! Just go for the cheapest one. If you want instead to keep the stock firmware, go for the 500W. It's simply the best you can get out of the 36V version. The same idea applies to the 48V version, but ONLY for Tongsheng mid-drive motors! For Bafang it's a different one. I hope this clarifies a bit

@@LukeLorusso sorry I made a question in this video dedicated to the osf but I meant a general choice. I am trying to understand the pros and cons of getting the 250w or the 500w . I exclude the bafang since I don't think it's a good idea for mountain tracks

​@@giorgio.plazzotta with the stock fw, the 250W would feel really slow... when I got the 500W I though the wrong unit was shipped to me, while instead it was actually the 500 one: it just felt less "energetic" I'll say go for the 500W: if you prefer to stay in the 36V space, you won't be disappointed!

@@giorgio.plazzotta if we talk about the stock firmware, on the power level there's no difference between a 500W @ 36V vs 48V. But, on the 48V variant you can get more range, cause you can have more Wh on the same battery size. If you take two batteries at 15Ah, you got 540Wh at 36V, while 720Wh at 48V. Then, if you wish to install the OSF, that 48V version will simply become a 750W unlocked one...

Ciao Fabio, vado un po' a logica perchè ora non ho il software davanti, ma se hai scelto il file _48V.ini come punto di partenza e non hai giocato col Battery voltage cut off, il resto dovrebbe essere uguale alla mia config 👍
