I use the 3.2, I prefer it at 3.1-CS (powerfull ramp a bit more slow) i haven't gap between cranks turn stop and motor stop. I don't know how is work the walk mode ? i never use it. For walk mode i use the throttle with mechanical range limit to walk at 4 km/h max. I find The gap with the 3.6 interesting in technical uphill, the raison why i remove it is mostly for the crack noises with it when you change speedToday I tried all the firmware I have in the rocky climb.
I have an FC1 with base firmware 3.1 as the basis. I have horrible cutoffs and a horrible rattling sound from the motor. It looks like I have torque sensor issues, because in the beginning I only had cutoffs on low-steep climbs and low assist levels, and now I have horrible cutoffs on technical climbs with strong assist levels (this is all on 3.1 firmware). My supplier sent me a warranty motor (unfortunately, it's still an FC1, but with 3.6 firmware). But that's just the backstory.
For the reason that I can't get my warranty motor yet and I have a besst I decided to play with the firmware.
1) 3.1 cs is the most natural FW. Like it, but I have the same cutoffs unfortunately. Riding without pleasure.
2) 3.6 is a terrible FW. Really dangerous. After you stop pedalling, the motor gives full power for 2-3 seconds. Yes, I read about it, but I didn't think it was that crappy. But I don't have cutoffs on this FW, hi bafang, if you decided to fix the crappy torque sensor behaviour this way, I'm not your customer.
3) 3.2 is something between 3.1 cs and 3.6. As a result, I have less cutoffs, but still have assist after stopping the pedaling. I also noticed that with 3.2FW I have a weak walkmode (but I had about 20% battery and that may be the reason).
I realize that I have a defective motor, but the behavior of the different FWs is so various.
The questions still remain:
1) Are there any FWs for the FC1 that you can suggest trying?
2) Is Walkmode on 3.2 so weak or was my battery capacity low?
3) I was playing around with BESSTpro, changing parameters (mostly angle and acceleration). When I change FW, those parameters don't change. Is this normal? Also, when the Besst box writes the FW to the controller, I get error 30 on the display, but the box still changes the FW. Is this ok?
4)Torque sensor calibration via besst. I have only been able to do it once, it is no longer performed. Is this normal?
Thanks in advance and sorry for any mistakes, English is not my first language
I never could perform torque calibration ? my torque sensors (older fail and newer sent by bafang) as never been recognized by the BESST tool. Or the calibration is weel performed, without any informations to indicate it ?
I have systematically "ERR 30" with firmwares who weel downloaded in BESST tool but who can't updated to the controle . For those i have checked (not all), the firmware who download and those who don't, have different 2 first digit in the file.bin. Someone with the same rev codification, exemple: bafang have sent me 3 x 3.6 rev, only one functioning with my controller.
