    I am in there with you and I have been doing many testing and am wanting the similar performance like my BBSHD has but can not seem to get the correct setting in the programming YET.Still working on it . PS" I ride during winter time as well but mostly use my BBSHD because of the way it works.

    Here are the 2 bikes i own i use one for trails and the other for mostly street and local paths mild dirt trails

    I have played around with many settings and seem to figured out how to DISABLE stuff but to make things work the way I want them to like the BBSHD is another story.

    I just changed some more setting today and will program the bike again tomorrow and see what happens and go from there Mine is the G510 1000W .

    UPDATE here are the new setting I have tired today everything seems to work well and much smoother and now I have throttle in assist 0 as well.

    The error VlowH voltage setting happened when i tried to use the same settings as the BBSHD with the Torque tab all 0's and the Pedal assist Tab using the (double signal-24) so its obvious that did not work was courious if with NO setting in the Torque tab maybe it would act just like the BBSHD does.

    Am still trying more later on with more updates

      To clarify, the problem we're trying to solve is how with the stock settings the motor gives a big boost then cuts out when there's no pressure on the torque sensor / pedals (ghost pedaling) right?

      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.

          I went with a whole complete new set of setting for everything and its working almost and I mean almost just like a BBSHD but smooth I was not happy with the stock settings that someone else suggested I do so I started from scratch and changed almost everything

            Some excellent information here eBikeaholic, well done for figuring these things out.
            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!

              Hi,

              I purchased the "Bafang BBS02 and BBSHD Programming Cable" from Luna Cycles for the purpose of programming my Bafang Ultra (Purchased through M2S). I read through the online instructions and am having an issue with the bandrate for the software. Who may be able to help me out to see what I'm doing wrong?

              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'm looking for settings that get me closer to a Bosch or Shimano feel, not a BBSHD cadence-only sensing drive. I'm struggling to understand why Bafang programs different torque mappings for different cadences (motor rpms) on the Torque page. I would have thought that the ideal here would be to have a variable torque multiplier. I put 20 Nm of torque to the pedal and Bafang puts out 30Nm. I put 30 Nm to the pedal and Bafang puts out 45Nm, etc. It shouldn't matter how fast I'm pedaling, it should only/mostly matter how hard I'm pedaling, right?

                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?

                  hmm... I'm not sure if the power is linear between MinCur or MaxCur, but so long as it feels like a smooth power transition regardless, would it matter? I guess we could play around with those to see if it feels any different but we'd somehow have to measure the kg going into the pedals at the same time, right?

                  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.

                    Is the UltraMag Program you're using the same one as the 'controllerst_torque.exe' one from Karl's post on electricbike?

                    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?

                      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.

                      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.

                      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...

                    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.
