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

What a surprise, i came to repport conclusions of my last ride with alpha 2.0, mainly a cadence problem (90 limit), and i see it is already fixed. All this is going so fast :D Another thing i tested, is the torque assist mode, and with multipliers between 0,5 and 3 it is very weak on motor power, i ...

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

And also, i don't understand the difference between Power mode and torque mode, as it is always a multiplier of human input. What is the advantage of using one instead of the other ? Power Assist: 1. Measure the torque sensor value and convert it to torque. 2. Measure the cadence. 3. Calculate huma...

Thanks buba for the answer about flashing .ihx, indeed it is working like a .hex file. I tested the bike this morning to work, and everything went great, felt smoother and more reactive (Advanced cadence enabled and calibrated, thanks to your video :thumb:). Just something confusing is that we have ...

I think today I ran into a similar situation, and i am almost sure that it has to do something with the boost settings... I encountered problems with boost, then fiddled in the boost menu (4) and the result was: boost still did not work, but then the whole bike worked worse than before i started fi...

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

Than you EC for your answer, I totally understand your previous recommendations. And I just can’t imagine anything smoother than 0.15.1 :D Just something I noticed on my way home, in level 5 for example, if I push hard on the pedals in a hill, I receive less watts than when I push lighter. The light...

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

I also made my first commute to work today with the 0.15.1 version today. One thing to say, it is really nice. My motor is way more silent than with previous versions 0.12 and 0.14 I also used less battery for the same distance. and assit is really smooth. I still noticed a 15% difference in battery...

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

And what precisely does the new ramp code ? I hesitate between flashing 0.15.1 and 0.16. Go with 0.15.1 for now, will solve the possible error on display (blinking 1) and is just an awesome version. The button issue has already been reported and is a low priority for me. Thank you EC, i'm going to ...

Oh what a cadence of releases :D I just flashed the 0.15 version this afternoon and already a new version. Feels great on 0.15 but : I also noticed buttons being unresponsive in Config when pressed too long. I started to play with off-road mode, and couldn’t figure out how to activate power limit wi...

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

Sorry to ask but what is stalled wheel protection ?
and what is exactly the problem reported by EndlessCadence regarding this functionality.

I'm about to flash 0.15.0 but if this problem ist fixed in 0.15.1 i may just wait a few days :D

Thank you,

Re: New "TSDZ2 Torque Sensor Central Motor"

In my experience, i use a little bit less battery (average) to commute to work with the open source firmware vs Original firmware. For the same travel time and conditions. What also helps to save power is the better customisation and modularity in assist levels. I'm still hesitating between 36V or 4...

Re: New "TSDZ2 Torque Sensor Central Motor"

Thank you all for all these informations about motors. But one more question is it dangerous for my 36V motor to run on a 13S Battery ? That question because if i order a 48V Motor for my other bike i would like to be able to use the battery on both bikes.
