    Tsdz2 watts/amps settings after cooling mods installed?

    I have a 48V TSDZ2 with a home made cooling mod similar to the ebikestuff full kit. I've set OSF to 18A/900W max on a 14S battery, with hybrid mode. I use my bike as a city/suburbs commuter, so lots of accelerations but no sustained max power more than a few minutes. My usual cadence is 70 to 85...

    They are both suitable for OSF (I used both). The black button version is more recent, and I found the following differences with the old one : - The soldering pads (for initial flash) are on the opposite side of the PCB - The waterproofing has been improved. It makes it a little more difficult...

    Thank you again for this work mbrusa ! The startup assist level choice is great on SW102 since the assist level is not permanently visible on this display. I noted a bug on SW102 : The bottom line, mostly used for temporary informations (like "motor init" during startup, type of assist chosen...

    For an easier access you can remove the dust cover of the CSK30P (without taking the gear out) : both covers are clipped into each other and you can remove the one facing you by carefully using a screwdriver as a lever. I did that to regrease it as it was slipping too, and had no issues since.

    Hi mbrusa, Thank you for this new version ! But on my computer with the java configurator, compilation fails (with the same settings as beta-0) : sdcc: Generating code... ebike_app.c:226: warning 158: overflow in implicit constant conversion sdcc: Calling assembler... sdcc: sdasstm8 -plosgffwy...

    Here you can find the wiring of the 6 pin connector of the controller, and this is the wiring of the SW102 (assuming you got one originally meant for a Bafang motor) : "Power Lock" is "Vin" on the page I linked. Note that you must wire Rx of the display to Tx of the controller, and vice versa.

    Yes I used the latest update of both firmwares, as well as the previous ones. I clamped an ammeter to the battery wire, and turned on and off the VLCD6 (before E07 appeared). The display wouldn't turn on again without disconnecting the battery first, and yet I didn't see any current surge. Same...

    Both ! With "Wait TSDZ2" the motor doesn't start, and with "e6 fatal error" the motor stops. It's always in the same order : first I get "Wait TSDZ2", then if I disconnect the battery, the screen and motor work for a few seconds to a few minutes, then 'e6 fatal error' and the motor stops. I...

    Hi mbrusa, thanks for chiming in ! The low cut off is set to 42V, for a 52V battery. I checked all connectors, including inside the motor, all seem fine. Indeed it's strange that disconnecting the battery allows for a normal startup, but the e:6 fatal error now appears a few seconds after that...

    Hi, another problem here.. TSDZ2 with SW102 and v20.1C.5. On startup the display freezes on the boot screen 'wait TSDZ2'. Unplug and replug the display doesn't help, but unplug and replug the battery allows for one normal startup. When the display is turned off again, the issue reappears at next...

    It's probably the CSK30P sprag clutch that needs to be replaced.

    That would actually be worst. Less voltage, so more amps drawn for the same power. But again, that would work. It's just not ideal.

    new tsdz8 pswpower

    The cells are Samsung 50E and it's a 2P pack. I think that would be a little weak if you're often at full power. It's more a case use for Samsung 50S cells. This pack would work but you probably will have a lot of voltage drop at high power, and premature ageing of the cells.

    New "TSDZ2 Torque Sensor Central Motor"

    Any advice on how to take out the HF1216 bearing from the cylinder thing that keeps it into the blue gear without access to a hydraulic press ? Also, when putting the new one into place, should I use a glue or something, or is the press fit sufficient ? EDIT : I managed to hammer (the heck...

    Thank you for your explanations. The smooth start is absolutely great for protecting the blue gear and drivetrain when starting from a dead stop, but I miss the snappy feeling when restarting pedalling after cruising, and I believe there is little chance to damage the blue gear when the bike is...

    Hi mbrusa, There is some serious magic going on with 20.1C.5-beta-1-860C... I've seen my energy consumption going down, and I even had to reduce my assist levels a little ! The motor also seems to be less struggling at high cadence and everything feels smoother... I assume this is due to...

    New "TSDZ2 Torque Sensor Central Motor"

    My TSDZ2 was pretty quiet at low RPM, but was noisier than I'd wish when pedalling over 70 RPM, so I decided to replace the fast spinning bearings, which are more likely to transmit vibrations. I changed the 696RS at the end of the motor shaft, and the 608RS and the 6001RS on both ends of the...

    Hi mbrusa, In case this wasn't reported yet, v20.1C.5-beta-1-860C works perfectly on SW102. Thank you so much for your work ! Is there a way to automatically set the assist level to 0 or 1 at the startup of the display ? For now the assist level stays the same as it was when display was turned...

    Hi mbrusa , I have what seems to be a small bug on 20.1C.2-update-3 with a VLCD6 display : With the 'walk assist debounce time' option on, when releasing the 'up' button, the motor remains active not just during the time set, but until a button is pressed again. So the bike keeps going by itself...

    Yes, extension connector glued, and different wires color for me too.. Would be allright if at least the wiring was correct ! Edit : Oh, I'm saying all of this because it's the connector on the TSDZ that I modified in order to plug a SW102 : I normally don't splice the SW102 connector and keep...

    Buyers of SW102 on Aliexpress, beware ! I just got a new one recently, to replace a broken one (user's fault) on my TSDZ2. The seller proposed 2 cable lengths, which I found unusual, but since it was a few € cheaper than the others, I went for it.. The display actually come with a very short (5...

    You need to do a hardware calibration of the torque sensor. The ADC delta is 300-230=70. That's way too small. The ADC no weight should ideally be in the 70-100 range. I had a torque sensor with a small ADC delta too, around 60. After a hardware calibration it went to 160 and the overall...
