    Anyone know about/tried TOSEVEN Mid Drive?

    This post from @stancecoke, on the DE forum, explains the operation of the To7 torquesensor through several illustrations.

    Anyone know about/tried TOSEVEN Mid Drive?

    FYI The torque sensor is a metal ring with strain gauges glued to it. These are placed in the To7 controller as a wheatstonebridge after which the signal is amplified. In order to measure the torque signal with another controller, a wheatstone amplifier is required once again. With regard to...

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

    Unfortunately, no. The seller doesn't know about it either. PSW always sold the old version, but now that is no longer so certain, but still the best chance. Enerprof always sells the new version. If PSW has integrated the new version not flashable too, you can consider to buy a separate...

    :bigthumb: Congratulations on finally finding the likely cause after all this time. I hope that the Java version can finally reach the same level as the 860C version without fear of a burned controller. 🔥 The main question is: Does correct handling of this Irq solves the ghost pedaling...

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

    36V sfw 81-150 and 48V sfw 81-153 looks both normal and indeed very similar, so you would expect about the same sensitivity. 36V OSF 156-95 looks strange to me with a "negative" range. Or are these values 0-95 the right one? (Personally I never have done this with a Vlcd5) Is this measured too...

    imho you can't compare torque values of stock FW vs OSF To know the sensitivity or full range of the torquesensor, measure the max. value with you full bodyweight on the pedal. 5kg is too few for a comparision, because the range isn't lineair.

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

    The sensitivity of all Tsdz2 torquesensors is different, so with stock firmware it is possible to feel that difference. You can read TE and TE1 with Vlcd5, but not change it inside stock firmware. Only with OSF it is possible to optimize the range of the torquesensor and the feeling between the...

    Cost reduction. In the past Tongsheng had reduced more components, like bearings.

    New "TSDZ2 Torque Sensor Central Motor"

    There is a good chance this controller isn't flashable. First is to check the settings. If there is an option to enable/disable the speedlimit, it could be such a controller. Second is to measure the speedsensor input. If you measure 0V (be carefull with power on), you can't flash this...

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

    You have disabled the calibration already to remove the E02, you have said. Because the hallsensor and magnet are outlined, so the range is decreased you can't do nothing more than accept that or line up the hall sensor again, by a hardware calibration. If you want to disable the torque sensor...

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

    Your torquesensor isn't the best, so these values are close to each other. That is the reason you aren't satisfied with the performance of it. Have you measured the zero and max. values again after you had seen the error 02? Because if the new measured zero value is drifted above the earlier...

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

    I read this and see you enabled/disabled the calibration. But have you done the calibration too (zero weigt and max weight on the pedals)? Which two values do you have measured? Without calibration the standaard range is 160, but practical most range values are around 100 to 120. Because the...

    Pull out the speedsensor connector of the motor and measure the motorside connector. You need to power up the controller and measure the pins (black and white on the picture) If you measure 5V you can flash OSF (without powered up motor) For OSF you connect STv2 to, red 5V, white Swim and black...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    No. The EU have as limit a maximum of 250W continuous power, not the maximum feasible power, that can easy be more as twice as much for a short time. The given 250W continuous is the power at which the temperature does not rise and is hardware related (dimensions, quantity copper etc) so this...

    No, it is Bafang 860C uart version. This display does only work with Bafang motors with uart controller. The canbus version of 860C will not work and also can't be flashed. A Tongsheng 860C can't be flashed too and is delivered as stock display for Tsdz2

    New "TSDZ2 Torque Sensor Central Motor"

    If you have the Vlcd5 you can check the Torque range with hidden settings. Te0 and Te1 are the same value without load on the pedals, Te1 will increase with load.

    If you had powered up the controller and measured 0V, then you can't flash the controller. :cry: May I ask where you bought the Tsdz2B?

    You can use the DIY without a problem, but you need to isolate the sockets with shrinktube. If you are not that handy it is better to buy the complete cable set. Because you have the speedlimit toggle the chance is there that the controller isn't flashable. To be sure you need to measure the...

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

    What you have done in hidden settings is changed the max. current setting, which can give also more power, but only if needed. As long you don't need this, everything will be the same. This setting is hidden because of the risc of burning the motor if you stay for a long time with that high...

    If you have this toggle setting you have indeed a non flashable controller (without SWIM port). On the old controller there is only a max. speed setting

    TSDZ2 48v 2020 new firmware

    What about the speed limit setting? Is there an enable/disable option for that inside the settings? Problem is, you don't know if you blow up the Swim port. To be sure if you have the old version controller pcb, you must dissamble the motor Here you can see the differences old vs new
