I join the question.
I uploaded OSF 0.6.5 to SW102 and tsdz2 0.54.0 today.
I noticed a strange behavior. When I start the engine while the program is loading, the lamp will flash and the engine will start for a moment.
The second problem is not remembering the settings after turning off SW102.
Hi, I have some troubles with my TSDZ2 and wonder if anyone can shed some light on the possible causes.
- First, the speed sensor broke, so I disconnected it and the TSDZ2 worked again, without speed limit....
- Then, after about a year of trouble free usage, the display XH18 stopped working, but the TSDZ2 still worked, max power only
- After a few months, the TSDZ2 stopped working all together. It doesn't seem like a mechanical issue
How do I go about with trouble shooting? I already partly disassembled the motor to get access to the electrical stuff. Couple of things I think I need tot test, but how?
- Torque sensor, no idea how to test
- Direct connection between motor and battery to test if it still runs. Which wires to connect?
- Could it be that there a short in the speed sensor connector which prevents the motor to activate??
Thanks in advance for any suggestions!!

To compare with .....? All releases have pro and minor points. It is the user who must weigh these points.casainho said:
I am sure that the latest release v0.20b1A (based on the latest release for lcd3) made a lot of difference, compared to the default FW. If someone don't want to replace the original display, flashing v0.20b1A (or v0.19C) is the better solution for TSDZ2.
With 3 different OSF forks there is a choice for everyone.

Seems like the 3rd time the motor controller broke. That could be due to the max power (more likely related to the high current running) been ran all the time through it. The first thing i would do is order a new controller and then test.

I looked at this web sites, but I wasn't able to find any charger as a separate item for sale (only as a bundle with motor and etc.)

Yeah their website isn’t that great. Try emailing them, and say you want to buy a charger only. They’re very nice helpful and knowledgeable so it’s worth a shot.
If not, I might be selling one of mine brand new, unused 90/100% chargers (still in the box)
My 17Ah batteries last so long that I don’t need to charge them both at the same time.

I know about this option, but this project seems to get less development support than OSF and it´s little less organized also (I don´t want to offend anybody, it is just my impression). I would like to stick with original firmware for now, anyway.

Thanks, will order one right away.

You can purchase the crank separately from the likes of PSW Power http://www.pswpower.com/ven.php?cargo.2016-7n-n002 but to be honest at 6.5K you may well be better to just front up for a new one, you've had good service and its time to be retired .
I can imagine what you mean. The main developers are Italian and don't work with Github. So you must be remain sharp to follow everything. So you are right it was less organized. It should now beiing a bit better, because stancecoke has given github support. The development is on par with KT lcd3 latest v.0.20, so that is not a problem.LJay said:
The latest releases are 850C (and SW102) only.

Hi
Yes, I'm getting samples of upgraded bottom bracket spindles made from EN24 thru hardened steel, if they perform I'll get a small batch done. Email me at dave@revolvemcr.com if you're interested.
Cheers

Can you show on a picture which part you’re upgrading? I have difficulty visualizing it.

Thank you for your offer. I´m thinking about another possible solution and that is to buy non-adjustable 54,6V charger and lower its output voltage. I just have to find any proven and reliable charger on ebay (ideally in aluminium casing for simple disassembly) and modified it (if it would be possible). Is there any proven type of non-adjustable charger to buy?

Are there any available informations about how often this issues occurs, prectagewise? I´m thinking about buying a new controller and swapping it for the old one, but it would be pointless in case the issue would be the same for a majority of available controllers on the market. In this case I will just buy/build adjustable charger and call it a day

Can't answer that question specifically, but, I know of two reported cases where someone with this 48V full charge voltage problem returned the unit for a replacement and the issue was resolved. I chose not to try the return route because the replacement is not shipped until the original is received, so weeks are involved! But this indicates that there is some chance that a controller replacement might resolve this for the factory firmware. Just thinking about it, I do not recall any 36V or 52V user complaints about this. Anyway, when I switched from the VLCD6 which does not report a voltage number to the SW102 with OSF which does, the voltage reported is 1.3 volts higher than a direct reading from the battery with a voltmeter, so, my guess is that the component on the controller board responsible for voltage measurement has a very loose quality check.

Buy yourself an STLink and reprogram the voltage, its very easy and only costs a few EurosLJay said:LJay said:

Using the stlink, I updated the data memory, as per the eco-bike article, to get past the 48V full charge voltage issue, but it had no effect on the problem. When I tried the 52V firmware to get past this issue (which did work, but caused the battery status indicator to show low-mid voltage), changing the data memory did work to restore the proper operation of the battery status indicator, however, the 52V firmware introduced another issue that led me to try the OSF so that I could use a fully charged battery.
Does anyone know where i can buy a 52v battery in the EU? I have TSDZ2 with OSF running 48v and i want to upgrade to 52V and leave the 48V battery for my wife's bike, which will is also getting a TSDZ2 with OSF.
Should i upgrade to the 850C? Is it worth the cost? I'm on KT-LCD3 for 1 year and 2000km. Running so fine, it's been great, trouble free.
