TSDZ2 OSF for all displays, VLCD5-VLCD6-XH18, LCD3, 860C-850C-SW102.

[Charlie Whiskey]

Just want to report a minor bug, when mbrusa gets around to it.

Running TSDZ2-v20.1C.2-860C, when the brake sensor is engaged, the word "brake" is no longer displayed at the bottom of a 860c display; the brake sensor otherwise works just fine.

This was working in TSDZ2-v20.1C-860C.

Hello everybody. My motor has firmware 20.1, VLCD5 display. After a long trip, error E08, after pressing the light button, E02. Broken torque sensor?

 

[Elinx]

... 20.1, VLCD5 display. After a long trip, error E08, after pressing the light button, E02. ...

E08 is a problem with the speed sensor
E02 shows de setting (depending of assist level) if you press light button

See the display manual of v0.20.1C

E08 - ERROR_SPEED_SENSOR
Faulty speed sensor or magnet too far away.

Thank you. I understand correctly, on firmware 20.1C, the speed sensor is monitored and, if it is absent, the motor is blocked?

 

[Elinx]

...... . if it is absent, the motor is blocked?

imho a faulty sensor is something else than "no sensor".
Disconnect the speedsensor and try.

E08 error is shown if the speed sensor is disconnected.

 

[Waynemarlow]

The motor won’t run if it cannot see a speed reading in some modes. You can however put the motor into Cadence mode and the motor will run to get you home.

I think you should be able to set it not to disable on error, in misc settings I think.

 

[galaxissurfer]

It's ready, I have to try it.
I plan to do it on the weekend.

Hallo from Germany, have you tested it?

 

[Elinx]

.... have you tested it?

Why so impatient?
It is all volunteer work done in his own time.
Give him the space to write and test the firmware whenever and for as long as he wants.
I'm sure, if mbrusa finds it finished enough, he will publish.
Nobody wants firmware with strange behaviour or a lot of errors, which raises a lot of questions and comments.

Yes I tried, all right.
There is only the problem of a drop in power beyond cadence 90.
Before the release I have to understand the cause.

E08 error is shown if the speed sensor is disconnected.

Error E08 is due to a faulty or unconnected sensor, or the absence of magnet.
The distance between sensor and magnet is no longer a problem, it works even if they are very close.
The presence of an error disables assistance in all modes. It is however possible to force assistance even with an error if this is caused by a sensor problem. Enable "Assist with error".

Thank you. And so it happened, the magnet turned away. Put it in place everything works. I am enjoying how the latest firmware works.

Continuation of tests 20.1c3. The battery wears out a little faster compared to 0.8. Normal temperature max 67°. But I did notice a strange unusual problem. Rather, it applies to full bikes. When we sit on the bike and support our legs (lowered saddle), swinging the suspension in hybrid mode and power assist, the bike runs away from the butt. The engine starts during a deflection of the suspension: / this problem appears to a lesser extent in the emtb and torque modes. I have a bicycle with a floating bottom bracket in which the pedals move backwards during bending. Many frames have a similar phenomenon, greater or less than. If someone has this soft loaded and the bike with full suspension, let him check it.
I was very troubled by strange engine jerking when I was driving around rock gardens and rtv/agd sections, a quick bend test at a standstill showed the reason.

 

[mbrusa]

What is the setting of the "Assist w/o pedal rotation" and "Motor fast stop" parameters?
With full suspension bikes, it is better to disable them.

 

[ilu]

I mechanically calibrated my torque sensor (range from 80 to 200) and installed version 20.1C3. I'm using 36V motor with 52V battery and display SW102. It's definitely the best firmware for this motor so far. I'm immediately a fan of the hybrid mode, using it with "Assist w/o pedal rotation" option, "Motor fast stop" is not enabled.

The motor response is super fast and hybrid mode works very well increasing power with higher cadence. With my setup the power goes up until I reach cadence 110, then motor starts to stutter. That is plenty enough for my riding. Field weakening is not enabled, but it didn't seem to make any difference to max cadence.

I have a full suspension bike and I have no problems regarding that, although the linkage is such that the bottom bracket doesn't move closer to the back wheel when suspension is working.

Assist w/o pedal rotation - disabled
Motor fast stop - I tried both settings on both the same. only faster the motor turns off after pedaling has stopped while this option is active.

this is how the suspension system looks like in gt

 

[w0utje]

Tried the 3th version on my 750watts mtb with 52v battery, works like a charm. Feels powerfull even with the lower settings and battery usage is like the 20.b version. Its better then with the first c version, about like 10% I quess. Higher cadance feels the same also above higher cadance then 90, still can do like 18km in lightest gear with 20.b that was like 14.
On my roadbike with 500watts motor and 48v battery I cant get it to work properly, is feels sluggish, not powerfull at all. The first c version and 20.b version work both just fine. Tried the same settings as with the first c version but cant get it to work properly. No clue why the 3th beta doesnt want to run properly.

Hi
Can you please tell me what is the difference between casaini and mbrusa version. Is the mbrusa version an improvement on the casaini version? Which is better and more stable these days?
Thanks

The problem you describe can be caused by a too abrupt stop of the engine or by the better reactivity at the start introduced in the latest version.
In addition to disabling "Motor fast stop", set "Motor deceleration" = 0.
Try to decrease the sensitivity of the torque sensor, see the calibration procedure.
Enter in "Torque adc offset" the value obtained without pushing on the pedals + 10/15, in "Torque adc max", the value obtained with the maximum weight on the pedal.
Enable "Torque calibration".
I hope it is decisive.

I have a motor TSDZ2 ,battery and 860C LCD and I´m waiting for bike all I had all flashed latest mmbrusa firmaware,but how it work virtual throttle. Please can you tell me

 

[mbrusa]

For Virtual throttle set and use: Street mode->Hotkey enable.
Available in Offroad mode or in Street mode with Throttle enabled.
"Motor max power" setting mode: While pressing UP, long-press POWER.
Virtual throttle: in "Motor max power" mode, while pressing UP, long-press POWER.
UP and DOWN buttons for setting and using the virtual throttle.

Yes it is working thank you , please where can i find a complete explanation of all the functions in the menu for the LCD860C such as this virtual throttle function where it is and how to get to it and use it. I searched but I didn't find it anywhere.

Hi,

First let me introduce myself; my name is Dennis and I’ve been following this forum for about a year. I’ve built 4 bikes with the factory firmware and recently converted my Cube Attention MTB and flashed the emmebrusa firmware to the motor and the SW102 display.

I think I need some help with the motor power settings. The motor is a 36V/250W and a 36V battery. With the ‘Power max’ setting to 250W the bike feels slow. I’ve changed it to 500W and now the bike feels like it should. After a short ride the motor does not feel hot. Is this setting acceptable for a 250W motor and should I install a temperature sensor?

Greets,
Dennis.

Yep just set this to 1000w and max amps to 18A and play around with the assist multipliers to get the type of feel you want. It will only climb above 250w in strong winds or up hills. I only adjust the power down when I'm running low on battery.

Unfortunately anything over 250w continuous will start overheating the motor... very slowly above 220w but above 350w it will probably only give you about 15 minutes and above 500w maybe less than 5 minutes.. Saying that its very rare to be running at over 500w unless you are battling a hurricane and want to maintain 40km/hr.. all depends on the terrain, speed and conditions.
