The distance between magnet and sensor is approx. 4mm. But it is the LCES 1075 frame from Light-Carbon. Had loaded the latest firmware and unfortunately the dropouts were back

Hmm…I dont have that. I only recognize cut offs when riding in higher PAS with very low pedal force - my impression is this is related to different torque sensing and my short 160 mm cranks. I just did 100 km of partly extreme trail riding at Zugspitz Arena, and Motor performance was awesome. Very powerful with low battery consumption.The distance between magnet and sensor is approx. 4mm. But it is the LCES 1075 frame from Light-Carbon.

SO different with my M510. A lot on off assist, maybe i will be back on m500 until good firmware can fix this on off problem.

By any chance do you have a low speed cut off setting (25kph ) and riding easy trails. If you’re riding at speeds around the cut off level the motor gets really confused as you’re putting in some torque on the pedals reaching say 24 kph, it starts to cut off power, you have to put in more effort to maintain speed, you give up and the motor now is sensing below 25kph and needing to put more power in according to the torque sensor.
My EZesty is truely awful around the 25kph doing this cutting in and out on one of the motors I have. I have a 32kph version same firmware and its smooth as.

no....I mean its like on off motor assist, not continue give power when i give some torquw on pedals, speed not more than 25kph pb flat terrain or light hill. tomorrow will try the other m510. i hope its jus one faulty motor.

This is really annoying. If I read about the overall experience in the group, it looks like almost everyone beside of me has severe problems with the M510 Motor, that seems to be related to torque sensing, pedal force and assist behavior.
There is an option to do torque sensor calibration with the BESST tool. Did anybody tried this with M510? Is there a description available how to do the procedure?

The problem is that the BESST Tool does not recognize or read a torque sensor at my M510

On the TSDZ2 project we found pretty quickly anything less than about 7mm clearance of the magnet gave rise to some pretty odd motor behaviour, have you tried pushing the clearance out to say 8mm and giving it a go ?
I had already reinstalled the old sensor with the spoke magnet and a distance of 10mm, with the same result
I don't get it either, I have 4 x M510 in Typhon Production sample bikes, and no problems
I fear my problems come from the fact that I loaded the 48 V firmware onto the 36 V motor

This is what happened to both of my M510 motor. Steady pedaling but power assist on off happened at level 1 and 2 on flat terrain and light uphill. Unconsisten assist.

loaded the 48 V firmware onto the 36 V motor. My m510 came as 48v and did exactly the same. With me it was better when switching from 5 assist levels to 3. But also then it still occured sometimes.
Now my m510 after a bit of rain is not doing anything anymore. Dried the whole bike and all connections with the air dryer, inspected all cables and the controller on the motor but nothimg. My remote will not switch on the motor anymore - when using the Besst Tool the remote workds properly and all 3 buttons do work without any problem. Nobody could tell me what might be wrong and in this cases Besst Tool is just not worth anything, eventhough there is a menu "diagnosis" but that cant just be used

It's very odd behaviour, I find that I'm riding mostly in 3 (out of 5 levels) as I just can't get the cadence/pressure right for 1 and 2. Even on level 3, it seems worse immediately after starting the bike up, almost like it's buffering the signal somehow, or maybe I'm subconsciously altering my cadence and pressure. Here's hoping a future firmware update fixes it! After about 5 minutes it seems to settle down, but this is all very subjective.

I‘ll have to check…will take a day or two…If I have time at the weekend I will open the engine to see if the cable connection between the torque sensor and the controller is ok. Maybe the plug isn't sitting right
@thaeber , can you read torque information with your display or BESST-Tool from your motor ?

From @c_pardo13 :
i have tested different firmwares in a m600 motor, and m500 controller in m600 motor, and sometimes, after flashing, the hmi dont turn on, but turn on with the best tool .
i have resolving manually introducing the serial number at the best program and reflashing with a original firmware
I can give it try although I'm not sure how it killed my m600 just by plugging in the rogue HMI from the M510

Today i change from 5 level assist to 3, even worse
The problem is when we reduce the pressure on the power assist pedal it immediately turns 0 power, it doesn't decrease slowly and then when the speed decreases and we increase the pressure of the power assist pedal it also doesn't go up smoothly. Only happened on flat terrain and light uphill.
But what I like is when on steep hill the power is good and smooth.

I do feel this, but only when I have very light pressure and torque on the pedals.
For riding where I have pressure on the pedals, the motor never cuts out unexpectedly.
same situation with me.
For me this is correct, and the way I believe it should behave
suits me. I have already written several times that the Giant syncdrive pro engine also behaves. To me at time can write on the screen 99.9kmh and there is no engine help. I stop wiping the sensor and everything is ok. i am using a spoke sensor, so there is a problem. I'm waiting for the disk sensor to come.

Besides the more power thing, I think M500 is more natural on light pedaling. I hope Bafang can make it more natural on M510 like M500.
M500 feel but more power on level 3-5 will be so good.
You must different firmware to what I have got. Before you ask, I cannot supply it to you.
@VMG Chris has bafang approved to share firmware on the forum?
