My other questions have mostly to do with which display to order If you want it simple and cheap, just use the display, that comes in bundle with the motor, no need to flash the display at all. https://endless-sphere.com/forums/viewtopic.php?f=30&t=98281 Tutorial: https://github.com/stancecoke/TSDZ...

I would suggest to connect the torque-signal to X4, as the plug of the throttle may fit to the controller as it is...

Sorry, please link. see here: https://github.com/AckmaniacSoftware/TSDZ2-Smart-EBike-compatible-with-original-VlCD6-display Also added a pull request to stancokes repository Sorry, but I don't want to do any work on this project, please contact marcoq to update his repo directly. regards stancecoke

Could X4 be used in place of the throttle wire? Or is that a digital input? You can use x4 for the torque signal, if you want to use the throttle in parallel. We discussed that in the german forum just a few days ago, I added the information about the wiring to the german forum. https://www.pedelec...

I'd like to get rid of the fork judder at medium speeds and medium PAS levels. sorry, in this case, the firmware can't help, as it's a known problem of the capacitors used in the KT controllers. The combination of the motorcoil inductance and the capacitance in the controller seems to lead to a res...

for a 6 FET, yes.

OK, first: you have to set the phase current limit to a much higher value than the battery current limit. e.g. max battery current = 15 amps --> max phase current = 30 amps. I'll add that hint to the wiki. If this doesn't help, you have to test differerent values for the Motor specific angle. All ot...

So I bought a KT 6 mosfets controller Is it a ZWSR type (no phase current sensor) or a SVPR type (with phase current sensor)? Is there anyway to use some kind of physical control switch for changing PAS levels with the android app, without an LCD3 or compatable dashboard connected? Not yet, we'll w...

Now its back to 1,7amps. ... The controller is S06S from bmsbattery. OK, then everything seems to be OK, the idle current is OK and the S06S has the phasecurrent sensor :thumb: Is the software developed here able to prevent this over-voltage problem? Yes, Xnyle has implemented an overvoltage limit ...

This picture is taken when full throttle and tyre in the air. 11Amps What kind of motor do you use? For a normal hubmotor, 11 Amps with tyre in the air is still much too much :shock: It should be about 2 Amps maximum. Again: is the current sensor installed on your PCB? 15 Amps can only be reached a...

you can build your own survey quite easily, everybody can take part here, e.g:

along with the KT 9-Fet controller w/Bluetooth

Be aware that you need a normal BT module for the BlueOSEC App. The BLE Module that comes with the Kunteng is not working with BlueOSEC, see the Wiki pages

If you (or anyone) could suggest the best known working combo I'll order it right away.

Sorry. I mean ordering the TSDZ2 or buying a torque sensor and a KT controller for use with my existing hub motor. Depends on your usecase. If you don't plan to climb really steep mountains and the speed is your most important need, you better keep the hub motor. The middrive has only advantages in...

Torn between this

What do you mean with "this". The torque sensor? The Kunteng Controller firmware? Higher speeds with which motor?!

But what is a pad x4 ? That's a solder pad on the pcb for an additional analogue input. https://www.pedelecforum.de/wiki/lib/exe/fetch.php?w=400&tok=2996b8&media=elektrotechnik:torque_wire_x4.jpg How does the above option compare to using CAv3 ? Pros: --> No additional hardware (and no quite ugly d...

36v --> DC/DC step down --> 12V --> red wire (supply)

gnd --> black wire (gnd)

PAS signal --> green wire (speed)

throttle signal --> white wire (torque)

If you want to use a throttle in parallel, you have to use pad X4.

I recommend the e-rider sensor https://www.aliexpress.com/item/33030138390.html?spm=a2g0o.productlist.0.0.26c5351d1AO5X1&algo_pvid=acc5808e-fd29-4824-be6a-8f982a431529&algo_expid=acc5808e-fd29-4824-be6a-8f982a431529-2&btsid=d3496ece-5a31-4d71-b6c2-7ad13a68ba30&ws_ab_test=searchweb0_0,searchweb201602...

This march I built a prototype with strain gauges on the crank and an HX711 module . The data transmission from the turning crank to the stationary bike frame is done by the SPI protocol of the HX711 via infrared LED RX/TX - pairs. It worked on the workbench, but I prioritize my Lishui opensource se...

Hm, the STC µC can be flashed via the display connector with a quite strange flash tool, see here: https://endless-sphere.com/forums/viewtopic.php?f=28&t=100064 But if you want to implement FOC you have to deal with the X8M06 :-( First you would have to do a Reverse Engineering of the schematic of t...

Does it require openocd?

openocd is only needed for debugging.

Hm, casainho and me splitted our developments on the Kuntengs one day also, as I had different prefers and finally casainho quit the Kunteng project to concentrate on the TSDZ2. Or fork a new project branch, that they can play with all they like, Yes, you are right, but it would be fine to have a ce...

When I start to ride under PAS mode, the motor works intermittently, with a creaking sound.

Ramp start bigger than timeout makes no sense.
Use a PAS with more magnets and /or increase timeout.
