Bafang M500/M600 Tuning & The BESST Tool

Does anyone have any idea why I can't install any other software to my m600?
I have the factory software version 46.2
CRX10NC4818i132046.2
There is no possibility to adjust the power on each level there.
I want to install different soft but it is the same every time. Aoft is sent is BESST TOOL (one beep), I disconnect and reconnect the cable from the controller, then nothing happens. Installation to the controller does not start.
Everything else works, I can read and change parameters.
I'm using software version 1.2.23 and 1.2.18, and it's the same on both.
The exact version of my m600 as in the attached photo

Use BESST 1.2.18, this works every time :).
First check if your python script is running and not showing any module errors. if yes, you need to fix them. start python from cmd.exe

-> see check_begin

then launch beest, enter random login/pass
in python there is auth.logs visible.

share them

Hi do you have a link for the python the link in here comes up not found
 
Hello, I'm having a problem with older versions of Best Tools below version 1.2.18. They do not detect the BESST device, it does not appear on the COM port. Does anyone have a solution to this problem?

Thanks mate but when I go to the login password py it won't let me down load it

I just copy data and paste into text file, then save it as loginbypass.txt and then change file extension from .txt to .py
Unfortunately it is not allowed to attach python scripts here
 
I was able to connect to my m600 version 46.2.
You can indeed adjust the current limit percentage in this software. Unfortunately, this does not solve the problem of hopelessness of this engine. They compare this engine to the bosch it works tragically. It doesn't have enough reactions to my leg strength. m600 works like my first old e-bike only with PAS sensor.
Example, I'm riding on lev1, I have a constant 120W when riding evenly, all of a sudden I push with all my force on the pedals and I still have 120W. It works badly and has no responsiveness. Until there is a software with access to the control "cycling parameter" and "support relation" this engine makes no sense and sets development back several years.
Do you know of any more soft versions under the new hardware? Currently known is 46.2 and 46.3 Is there anything else?
46.3 I tested and in this version you can not change any parameters.

Hi, do you have 46.2 bin file?

U can only change the basic parameter. I have 46.2 controller and it works. But indeed this M600 not as good as M510 FC 2.0 that is so responsive to our leg pressure and all parameter can be tuned.

Is there still problem exist with m510 erratic power supply?

Did you have a chance to test the new firmware? Do you know what Bafang did modify in the file they sent you?

Besst tool received with a dealer login so I have tried the modified 46.3 firmware. It is certainy changed from the default 46.3. L1 power is now good with maximum 100w output, ideal for low power use on flat trails to conserve battery. L5 was full power but will need to test on my local hill climb to check how it responds to cadence and torque input. Will be interesting to compare to 14.6 which is my preferred FW so far. I have downloaded 14.6 from Github file library but for some reason it will not load using the update function on Besst. I select it ok but it seems to fail a compatibility test and wont upload to the Besst box. Does anyone have an original Bafang version of 14.6?

Usually GitHub has original Bafang files. Try using besst-pro to flash old firmware. The account they provided also may have restrictions.

Do you find torque sensor response to pedalling on new firmware similar to the old one? I wonder if they changed hardware in their new motors. Some people complain that only cadence sensor is used to calculate the motor output on recent m600

You have a newer hardware version of the M600. You won't upload old software versions to it, i.e. 14.6 for example. For the new hardware version there is 46.3 and 46.2 as far as I know. Unless there are some more then someone please correct me.

what version of controller do you have?
I could not install this firmware on my.
 
I got a new controller for M600 with version 46.4, but I can't change the settings of the assistant in Besst tool.

From what I can see all 3 of my M600s are the same version with the controller hardware CR X10N.500.FC 3.2. I will connect the latest motor running the modified 46.3 FW using BESST Pro and see if I have access to the motor parameters and report back. Testing so far with this version is promising with lower power and support at L1 (max 100w) which is very natural feeling and full power at L5. Riding the big uphill test on Sunday so will confirm after that.

From what I can see using the information access via the display, all 3 of my M600s are the same controller hardware with the description CR X10N.500.FC 3.2 . I will connect the latest motor running the modified 46.3 FW using BESST Pro and see if I have access to the motor parameters and report back. The modified FW provided is definitely different to the stock 46.3 so it was clearly adapted for me by either Bafang or the folks at Dengfu.

Could you share your 46.3 software rev ? or if somebody have the 46.2 (i have asked to bafang, but no answer). i have recover some 46.3 on netwoork, but it don't download to the controler 500FC3.2.

i have tested 46.7 and 46.9 and i find 1 level to powerfull

I have attached the revision earlier in this thread. It is looks like it has set L1 at 15% power and then 35 55 75 100.

I have the same controller hardware (FC 3.2) and it uploaded just fine. Strange that we are not experiencing consistent results.

i suspect that it existing several soft with same number, but following your country localisation (and rules), BESST tool block the download. Bafang have provide me 3 x 3.6 revision for the M510, but only one downloaded to my motor.
 
No

You have old M600 controller. You will be able to flash only fw with bootcode 0x89. So you wont be able to flash 46.2 or 46.3.
