Hallo zusammen
Ich habe eine Grundsätzliche Frage:
Spd 0 bis Spd100: Was bedeutet dies genau? Spd0 = Geschwindigkeit 0 in % oder Trittfrequenz 0%
Da würde es ja Sinn machen, zum beispiel beim Bergfahren wo man mit "kleiner Trittfrequenz bzw. kleinem Tempo ca 50% fährt - die Start und Full Kg herunter zu setzen und nicht bei Spd100.

How would you "power the motor on" if the display is unplugged?
You need it plugged in to a battery though but that's not the same as turned on...
-
Have you tried doing it with the motor powered off? ...I always do it powered off and have actually never tried it with the motor powered on.

My first step is to power the bike on. Then I disconnect the cable from the display. Next I connect my communication cable to my laptop and to the bike. Using the 'controllerst_torque.exe' program, I enter the com port, (in my case, "COM5") then hit the connect button. The "Bandrate" window constantly scrolls and never connects. I know my bike is still turned on as I can hit the throttle and it will lurch. What am I doing wrong? I can't connect to the controller.

I downloaded the UltraMag Program. I found my com port (COM5) and entered my Bandrate (9600). For some reason, the Bandrate keeps scrolling and won’t fix on 9600. It’s begins scrolling after I hit the connect button, which is prior to me connecting the cable to my ebike. I tried running the program under windows 8, (my computer is windows 10) and that made no difference. I even used an older windows 8 laptop - still no difference. I cannot connect to the Ultra controller. Anyone have a similar experience with this?
My goal is only to reduce power levels on level 1 and 2. I'm not even trying to increase power!
Any help you can provide is most appreciated.
I never had to enter the bandrate. After plugging the cable into the controller and the computer, then choosing the correct COM port - I click connect and it automatically chooses the bandrate. Does that help?

Two quick questions:
- is the power delivery between MinCur and MaxCur liniar, depening on the pressure between StartKg and FullKg? What I mean is, if you have a StartKg of 20kg and a FullKg of 50kg, can the controller only deliver either MinCur or MaxCur power, or somewhere in between as well, if the pedal pressure is say 30kg?
- if you set ReturnKg to 0, does this mean that the motor keeps running, even if you stop pedalling (potentially dangerous and reliant on the brake sensor working - if you have one), or does it still require for the pedals to turn (ie ghost pedalling without much/any pressure)?
Thanks for clarifying!
I have ReturnKg all set to 0 . I believe it allows the motor to keep running so long as the cranks are turning - even when there is no pressure on the pedals (ghost pedaling). The motor doesn't activate if the cranks are not turning,. If you lift the wheel or put it on a bike stand and the cranks spin themselves it will continue to run until you grab the pedal or tap the brake switch - otherwise that could be dangerous for sure, fingers beware.
I recently converted the bike to Nexus 3 speed and shared a video showing how it feels... might be insightful.

And then, instead of different power limits, I'd want to choose different torque multiplier mappings. One for on-road commuting, one for on-road speed, one for off-road singletrack, one for off-road fire roads, etc. Thoughts?

I noticed some of your torque settings are same as mine, are you still having issues with that?
Return(kg) - all 0's, and KeepCur(%) - gradually increases. I believe that alone should keep the motor running consistently regardless of how much pressure is being applied to the torque sensor while riding (or ghost pedaling). My motor is running consistently with throttle and/or ghost pedaling regardless of the hill grade. I also have the first three tabs (basic,pedal, throttle) and the top section of torque set to stock settings.
