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

For me Buba the greatest thing you have achieved with version 20 is to make it possible to go back to the blue gear again. The power is still there but is now delivered in a controlled manner. A couple of hundred miles of testing has given me the confidence to take the metal gear out and put the pla...

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

FYI - the newest version with imperial unit/throttle/etc support IS NOT AVAILABLE YET for the bootloader, but is expected shortly. The bootloader DOES NOT USE THE SAME .bin FILE THAT YOU USE TO MANUALLY UPDATE!!! Any ETA casainho? :wink: Great work eyebyesickle it will be a game changer not to have...

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

I am curious of the sensitivity users have set on the eMTB mode so it would be cool if everyone could vote on what they are using. Please only vote one time. I am sorry for the "User ID" question, you can write whatever you want on that one and you do not need to share any information. https://docs...

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

Optional Alpha 7 is released! No big changes and no need to update unless you want! There is one small bug fix! No need to update unless you really want the latest changes or if you were affected by the click sound when enabling the brakes. The click sound was present when the motor was rotating an...

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

Users using the imperial system: Not saying this will be possible to implement due to program space constraints but want to know if there is anything I have missed that should be sorted out. Just so that we know. Here are a couple of things I have noticed: - Motor temperature in Fahrenheit - Pedal ...

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

No serious problems to report at all with A5 Buba, Throttle is job done. :D Seems safe now with no tendency to leap forward when stationary and foot resting on the pedal which is very important, I like the speed of the digital read outs I think you have got it just about right. My favourite mode for...

Phew I'm glad you posted bwb I was just about to set off for a ride too. Same problem for me with the drive. While quickly testing the modes ( stood by the bike and also using kick stand at times) after reading bwb's post but before disabling the throttle I did end up with a situation where the bike...

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

Quick update: Need to improve the filtering on the display. This is the last thing I have to do before releasing the Alpha 4. Alpha 4 will have the following improvements: - More accurate watt-hour calculation - More accurate motor temperature control - More responsive throttle than Alpha 3 (I saw ...

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

Also, you need to be testing "live" as there needs to be a load on the motor for the throttle to work. And live it works perfectly :thumb: As the throttle was not working correctly live in A2 and was giving the same results in the advance technical data on A3 I never took it for a live test drive. ...

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

Hi Buba just a quick comment on A3. The throttle is still acting as an on off switch. The throttle I have by the way came with the original purchase of TSDZ2. The readings in 11.1 are exactly the same as I had in A2 in that there is speed control from 0 to 30 (zero speed to max max speed) which is s...

- Maybe improve the throttle depending on user feedback

I did answer your questionnaire on throttle data Buba but you may have missed it with the deluge of responses you have had in the last 3 days :)

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

The backwards resistance in the new software is intermittent. For example power up and enable the 3 different modes (PTC) in turn and it is there and also in eMTB mode but after using walk assist there is no backwards resistance, then switch off and on again and it is back use walk assist and it has...

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

Throttle still behaves as an on off switch but suspect you know that. Did not know that! Same thing on the 0.19.0? Have seen conflicting reports stating that it does work and others that it is like a switch. I have the temperature sensor so have never even tested the throttle on the open source fir...

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

Buba Im still having a problem getting my head around cadence mode, surely there is more than a cadence input from the way it is behaving. I'm running on a Nexus 8 speed hub gear and 48v motor, 52 volt battery Max 18 amps and 800 watts set. To get any decent response I need the cadence assist set at...

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

Startups: We need to confirm that the user is rotating the pedals to enable assistance. I don't agree on this, otherwise the throttle alone could not be used. We can provide motor assistance as soon user makes a specified minimum amount of force on the pedals, even before they start rotating. Besid...

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

I would first like to say that mine is a personal opinion. This is so that no one is offended, my opinion counts very little. I like riding bikes more than setting engines and it doesn't matter if the display isn't colored. I also have a turbo levo and I can make direct comparisons. With tsdz2 I ca...

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

I have to be more precise. A short circuit occurred when the speed sensor cable was broken. For a moment the engine stopped and I saw the speed of 56kmh on the speedometer, even though I was almost still. Then I unplugged the connector and it all started again. So in fact a short circuit between th...
