Why? Did they change the firmware to make it work? What is the exact problem?

No it’s standard vesc firmware. v3.65 I believe but all sellers of this esc seem to say reverse and battery indicator function will be lost if you update the firmware. I’m not sure why that is though.
that’s old…

I’d just make a stack of speed washers until it’s 11mm thick

I knew those speed rings I ordered would come in handy

Yeah it’s a pretty old firmware version. I’m just really confused as to how a voltage reading being forwarded to a remote can be affected by the vesc firmware version. I’m hoping @esk8supply can explain.
Just for context I want to run a loaded/ ride unlimited hub motor which doesn’t have sensors.
Actually I think it’s v3.65
how are you checking the version?

Going off memory. I’ll have to check my computer to see what version vesc tool I used for it.
Which remote / Esc is this? @Esk8supply seems to have a couple? are there docs for how the remote gets it’s voltage reading?

That’s all the info I have on it.
hmm. some kind of integrated receiver. my guess would be they have a forked version of the firmware to work with it? but also claims to be ppm type.
but:
If you have 1.06 vesc tool, try that first due to the increased functions you will get.
did they mean vesc firmware or vesc tool. … what version do you currently have? hooking up vesc-tool to it should tell you in the firmware tab even if it doesn’t let you do anything else but upgrade.
but that numbers old for either. weird.
i look forward to the answer to that riddle.

Found this at bound motor:
“Please do not upgrade the firmware, this version compatible with FW 3.65 only（VESC TOOL V1.29）, otherwise, some functionality will be lost, such as speed mode switching and front-back direction switching.”

It sounds like they are using modified firmware. If this is the case, it’s an easy fix. Just port their change into the new version.
@Esk8supply Where is the firmware source code that ships on the ESC?

oh oh… here we go… sally forth for science brother
Any way to extract the source code if I still have it on the vesc?
