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

The compact SW102 is not really a suitable like for like swap with the excellent LCD3 display though. When I first purchased LCD3 for the open source project I was a little underwhelmed by it but soon grew to respect it. It is so easy to read in all light conditions, at wide angles and vibrating awa...

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

Buba Reading the comments I noticed that 25kg is discussed as the maximum high calibration for the torque sensor. I had not noticed that 25kg max when the torque sensor cal was introduced into the settings menu, has the Wiki been updated down the line or did I simply miss it? Anyways I assumed the h...

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

working with bafang engines is a good idea. But the bbshd is too powerful. There are transmission problems, the chains are broken, free wheels and hubs. Even the rear of most bicycles flexes with its power. I have been using a BBSHD for far longer than the TSDZ2 and what you say is quite frankly wr...

There is absolutely nothing wrong now with walk assist as it is. If it ain't broke don't fix it.

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

I am making an alpha where you can set the button bounce time. In your case your would want it to be 0 so it deactivates immediately. I hope that is okay with you. I want that smile back so please test eMTB and let me know if you are happy with it after changing the sensitivity so it fits your old ...

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

Re A8, Sorry Buba because I realise you have put a lot of work in. The mod to the walk assist which means that the bike carries on for another three feet after releasing the button is not acceptable for me. I need the bike to stop as soon as I release the button especially on a route I use which has...

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...

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...
