Going for a world record for thread resurrection here.. :lol: Did you ever find a fix for this? I've got one of the early BBS02's that has this pulsing issue (under PAS, throttle is ok), a slightly later version of the drive I also have doesn't have this problem. The only programming option that see...

ASSIST_LVL_AFFECTS_THROTTLE causes extra float calculations, I don't know, if geofft has activated this option. No, I don't use this option, I prefer to have full throttle available in all assist levels. Would just add that since switching to the 'Torque from X4' branch (from Xnyle's torquesensor b...

So I basically just copy/ paste /replace everything starting from line 211 of ACAsetpoint.c from the "Torque from X4" -branch to the master branch and flash with my normal parameters? Correct? I'm wondering if you couldn't simply use the 'Torque from X4' branch and just de-select the 'Tor...

Hm, has anyone tried to increase the deadtime? Yes, under Casainho's instruction I played around with increasing the deadtime many moons ago when he was investigating this issue. We also played around with the motor angle to no avail. I have also tried running with 'pwm off at coast' selected but w...

My current configuration right now is the controller is placed inside a saddlebag on the downtube, so placing it outside the bag would give it a significant amount of airflow. The only problem is cable management but I'll figure that out somehow.. My solution here was to make a largish hole in the ...

I've reduced the battery amps to 10A and phase amps to 20A and the controller is still getting worryingly hot :( Im at my wits end right now It is a known fact that the OSF seems to produce more heat in the controller than the stock firmware. I think this is down to the way that the pwm is operated...

Can't help with the display question I'm afraid, I think the LED880 is a Kunteng product so you may get some communication if you use the KT-LCD3 option but I wouldn't bet on it. If you only need power on and light it maybe easiest to dispense with the display altogether, just fit a by-pass plug on ...

I just wanted to double check if I can flash this firmware into my KT48ZWSRKT 18 mosfet controller with an LED 880 display since I couldn't get much info about this controller. Copied from the wiki.. Q: Can I use a KT36/48 ZWS type controller A: As the ZWS type has no phase current sensor, you can'...

I have the Stages power crankset on my main road pedal bike. Man, if you guys could get those or the Garmins to work with a BSHD that would be the bomb for sure. Yes, they are expensive, costing more than the motor kit itself. But it would make an almost perfect torque sensing e-bike. I'm really su...

I'm having a lot of issues with a 60V+ 18fet controller, and many users here had the same issues with 18fets : resistors + LM getting VERY hot that it needs to be replaced by a DC/DC buck, controller not powering up due to wrong volt cal (the wiki is wrong for this part, as I said above). I've read...

I drilled a hole to the side of the casing, sealed the lm317 with kapton tape and the big resistor with heat resistant tubing from touching the screw and clamp. ...I've been running a similar arrangement on my controllers for some time now, with no issues. The end caps of of the big resistors are u...

Ok. Now that I have chilled a little. Let's buy the 7th and 8th controllers for this project but please help me. Before doing anything stupid, let me get this workflow straight( and sum up what I have learned this winter): 7. If for some reason speed oscillates I may try to lower both Gain values. ...

How to find the right motor specific angle so that I don't accidentally do this same thing again?

....stancecoke describes a method on page 170 of this thread.

Troubleshooting help needed: I changed hall sensors to my geared hub motor(52V battery/S06S controller). Last night I flashed S06S with OSEC and tried to find the right motor specific angle. I started the controller and the wheel started to spin on it's own without throttle. I tried different motor...

'Seriously impairs' ? Any road tests by someone to support this claim? I remember during earlier testing of the fw at one point I tested the difference between FOC on/off with the bike on a heavily loaded training roller. The difference was very noticeable, with foc 'on' the motor sounded and felt ...

Quick question is this OSFW compatible with the S-KU63 controller if not what are the required modifications (maybe changing CPU?) or do i really need the KT36 or S06S controller? i'm a rookie on these subjects its for a school project :oops: The usual problem with using non sinewave controllers wi...

I do have Bafang motor with 6 magnets for speed reading. How to setup this properly so i can get real time speed read? Shall i select "external" speed sensor? How about defining six magnets? Appreciate any response. I think if you select 'External speed sensor' and then divide your wheel ...

Thank you soo much, @stancecoke!! That really helped me a lot. @geofft: Funny thing: I ended up with almost the default setting, as you recommended. :) '239' brought me down to minimum measured current (1.3A) .....thought I'd give stancecoke's wheel-in-the-air-current-measurement method a try, had ...

Esp for the angle, I can go from 1 to 255 and I find multiple 'maxima' settings where the motor sounds smooth and fast running (all tested w/o load -> wheel in the air). However, at the fasted & smoothest setting (around a value of '15'), the current draw (as per BluOSEC App) goes unproportiona...

How does the torque from x4 branch work differently? I can't really find any documentation on it. I run the a torque sensor, so by the sound of things I could use it. The 'torque from x4' branch allows you to run both throttle and torque sensor together by connecting the throttle as normal and the ...

Also: Is this known freezing problem only happening when one actively uses the BluOSEC app (i.e. while there is a Bluetooth connection)? I was getting what I think was the freezing problem when using Xnyle's 'x4throttle' branch. This was with the lcd3 display i.e. not using the BluOSEC app. The mot...

Looking to upgrade my controller to a KT. Is there a recommended place to buy from? I see bmsbattery linked. Are there other places as well? For 6-fet versions (and other accessories) I've also used PSWpower:- http://www.pswpower.com/ven.php?cargo-s220052 ...they've been a reliable supplier for me ...

How much current capabilities does these S06S controller wires have to have for the controller to work properly; Throttle: +5V, GND, signal Brake: +5V, GND, signal HALL: +5V, GND, white, green, yellow, blue -signals PAS: +5V, GND, signal Display/bluetooth: +5V, GND, RX, DX, blue I'm planning to use...

Hello guys, I'm new here. I compiled and flashed the firmware on a KT36/48SVPRD-HRD01 controller. I get no error at compiling (with proven setting: THR-PAS,KT36-48svpr,12s,26inch,Q128h + Diagnostics), Just a couple of things worth mentioning with those settings. The throttle min/max numbers were fo...

Well done! It sometimes takes a bit of patience and experiment to get it to run how you want, but it's worth the effort in the end.
Like you say the feel of a torquesensor bike is quite special, getting back on my BBS02 equipped bike just doesn't feel the same any more....
