Thanks cyclebuddy - the video does give me some more information. I'm a software engineer by trade, so the open source route gives me complete flexibility to understand exactly what's going on, fix bugs as and when I find them, made modifications and improvements, and generally change things to be exactly as I prefer them. I like the 'off road' mode of the open source version where I can easily switch between UK road legal and a higher speed limit. Also, the potential to get the maximum efficiency from the motor and therefore longest battery life is a good thing.

Hi all. I have a Fiido D2. I've changed the controller for a KT36/48ZWSRTD-SJT02L2 - it's mostly working with the original firmware supplied with this controller (I'm still waiting for the KT-LCD5 to arrive), but I intend to change the firmware for a build based on KT open source firmware I've got the firmware to build OK, my problem is knowing the values to plug into the configurator tool, like number of poles on the PAS sensor, maximum phase current etc, as detailed here: KT06 Configurator tool documentation Just wondering if anyone has already done this so I could use their parameters to save me the pain of discovering them myself?

I took it apart to find out which controller it has (it's a WK3612YS), but I couldn't find any information on programming that. I then trawled the internet for any general ebike speed limit information. I stumbled upon "the mad Rumanian", who on a completely different ebike, disconnected the short white wire that comes out of the controller and goes back into it, and that removed his speed limit, so I searched for the same on my S6. Not quite the same on the onebot S6. I found a short (10cm) black wire and a short white wire - neither of them were connected to anything, but one had a male and the other a female connector on the end. I took a gamble and connected them together. Hey presto, a slightly faster S6! I then tried various combinations of the three P3 settings - I don't know exactly what they control, but by changing them you can vary the initial pull away torque and the highest speed. I found the best compromise to be as follows: P3-1 = 3 P3-2 = 6 P3-3 = 7

I've just got a new Onebot S6 ebike (very cheap on ebay). It has an LCD. I can get into programming mode, by holding the + and - keys both down together for about 5 seconds. I can then scroll through the various parameter, but there aren't many of them, and I have no idea what many of them mean. Can anyone help? P0 - First thing that is shown - doesn't seem to be anything to adjust here P1 - 0 = km/h, 1=m/h P2 - default 15.6 - can be changed to anything - I think this is a wheelsize/speed calibration value. If I increase it, it reports that I'm going faster, but I don't believe that I actually am. P3 - 1-2. Can be changed to 1-3, 1-4 or 1-5. No idea what this means. P3 (again) - 2-5. Can be changed to 2-4, 2-5, 2-6. No idea what this means. P3 (again) - 3-8. Can be changed to 3-7, 3-8, 3-9. No idea what this means.

A bit of Fiido D1 battery information... I took mine out. It has a sticker on that says all of the following: FarNess Shenzhen Huaruillin Technology Co Ltd Lithium-ion Battery Battery Model: 18650-10S4P Capacity: 10.4Ah/374.4Wh Standard Voltage: 36V Cell: 18650-2600mAh

I've just posted a thread entitled 'Fiido D1 controller configuration/information' which might answer your question.

I have a Fiido D1. In line with UK/EU law, it is limited to 15mph (25kph). I managed to find some information somewhere on the internet that suggested doing one of the following things would remove this maximum speed limit (sorry I can't give credit to the appropriate source for this information): 1) Hold the brakes on. Turn the power on. Wait 5 seconds. Release the brakes. Power off. 2) Hold the throttle on maximum. Turn the power on. Wait 5 seconds. Release the throttle. Power off. I can't remember which, but one of these worked for me, and now according to the GPS on my phone, the Fiido D1 can travel at 19mph on self power alone. Whilst doing this, I noticed that the small battery icon on the bottom of the LCD flashed a certain number of times: Twice if I held the brake and powered on, and 10 times if I held the throttle and powered on. In wondered if there where any other combinations of inputs that might change things. I tried a few. It seems that: - Left brake is the same as right brake is the same as both brakes held on = 2 flashes. - Throttle on full with left, right or both brakes = 10 flashes. I know that one of the combinations removes the maximum speed limitation. My initial questions are: A) Does anyone know what the other one does? B) Does anyone know if there are any other combinations of inputs that will change anything else? C) Does anyone have a user/programming manual for the controller? [Mine is a WK3615MS dated 03/2019 - internet searches for this model number have so far drawn a blank].
