    Glad that I could help a bit. It is very valuable to have proactive users who test changes. Thanks!

    I made the changes of 2 ADC units for torque. Also added min cadence assist ONLY in case of non boost mode. The logic is complex and I did not want to impact it. I was not able to make a branch or a pull request(I get error at push) @casainho can you please give me rights to be able to push a...

    From what I know 14.3 only has only high cadence enhancement for 36v on experimental mode. No lag fixes are there. I think we can have that if we have a miniman "human power" in the code. I did not have time to test it. Now the cadence goes from 0-max_cadence. I plan to have a range of...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    I managed to fix my engine interrupts issue. I did a reflash of the LCD and does not happen. So no hardware issue. However i noticed other problems visible also with reset to defaults: - now odo meter is always reset after power off - battery cut off voltage is 0, i had to put it back to 54.2v -...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Today on my way to work and back I started having a nasty issue. After 2-3km of riding in city i get constant short power cut-offs. For 1 sec aprox power drops from 2-300w to 10 w then goes back up. Than after 30-40s I get it again. It is like getting hiccups from the motor. I checked all diags...

    I know that the stock soft connects the power instantly. Can we decompile the hex and check what is it doing the cases mentioned by you? Perhaps there is an easy way.

    Hi Jblat, I need some help to make this work on 48v. I do not want to kill the motor. Any sugestions to the FOC angle? Now it is 143. I was thinking to test at 175. MOTOR_OVER_SPEED_ERPS_EXPERIMENTAL 700 should remain same? Regarding power, I changed MAX_CANDENCE to 95 because i was limited...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Ok, I see I was not fully understood. I'll try to rephrase. 1. "2 sec lag" = for me this happens like this: From full stop or while riding with pedals stopped I start to pedal. I get no assistance at all if I start to spin the pedals and apply serious force on pedals for 1-2 seconds. I think...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Hello, As improvements I see the following in the priority order: 1. "2 sec lag" - This is already known. I think there is a problem in reading the magnets count (PAS issue). I needs more to connect the motor. If you have higher cadence the lag obviously gets smaller. 2. I have 48V 17Ah...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    I did 50+ km with 14.02. Not bad at all! :) I run it mostly on flat ground but also did some climbing in the park(tested with default settings). What I like: - Power is delivered linear without the cadence limitation of the old soft. As a comparison I was able to run similar medium effort 45km/h...

    New "TSDZ2 Torque Sensor Central Motor"

    For programing cable I used the LCD cable (motor side connector so it fits). I was 25 cm long. => error I made it 10 cm => error I realy did not want to ruin it :((. I checked cable connection and is 100% valid. Regarding laptop, I run a decent I7/12GB with windows 10. Maybe my STLINK is the...

    New "TSDZ2 Torque Sensor Central Motor"

    I managed to finally read the motor firmware.... It was a nightmare! I do not know for sure but I think the wires on the motor are longer than others or they have some bigger electrical resistance. Botom line is that I only managed to read the firmware with 10 cm cables(in total!!!) directly...

    To make cables even shorter I connected directly into the board! Same result. Please see picture. I made swim on black wire pin, reset on purple, ground on LCD black wire. Please see picture. I have the LCD cables cut out. Is this a problem? https://imgur.com/a/jHlqWDS...

    Hi Casainho and EC, Great job with the code quality and new release process! I would like to help with the development of the product as well. Seems you are quite loaded now and I have some spare time this week. I have software dev experience, but for now I would be happy to help with the...

    You do not need to fully open the motor case. You only need to open the 4 screws and you have 1cm access until you hit the crank. This space is enough to pull the conector out. My goal here is to be backwords compatible.If I want to sell the motor, all I have to do is to flash back the motor...

    New "TSDZ2 Torque Sensor Central Motor"

    Hallo, I took a look on the Git repository and I really like the way the C code is written clean and documented, clearly good dev work. Respect for casainho and the others who developed it. This has convinced be to order the KTlcd3 :) today. I will get in in 3-4 weeks I hope. Meanwhile I am...

    New "TSDZ2 Torque Sensor Central Motor"

    Hi guys, I see a lot of good feedback on the opensource firmware. Can this be flashed in the standard vlcd 5 or it works only in ktlcd 3? Is there a way to reset the odo in the vlcd 5? It got messed up by the 99km/h error. Thanks.

    New "TSDZ2 Torque Sensor Central Motor"

    Hi eyebyesickle, bart! The problem was that the magnet was too close to the speed sensor. Exactly like you said! You need at least a 3-4 mm. I read a lot of this thread before deciding between Bafang and Tongsheng. I think I made the right decision. This engine has a very nice normal bike...

    New "TSDZ2 Torque Sensor Central Motor"

    Hi Guys, I got TSDZ2 750w 48v with vlcd5. All was excellent until 150 km. Now at low speed (smaller than 10km/h), I get 99km/h speed error and the engine disconnects. The engine gets connected back when hitting 10km/h+ and all is good. This very bad because I can no longer climb hard slopes. I...
