Finally had the time to update the unity, and it works great 
Metr CAN + Davega X + Maytech V2, just need to work on cable management here, it’s a bit messy
Works just as intended using usb flashing, you have to rename the bin file tho, vesc tool refuses to read it with its current name (i renamed it to VESC_custom.bin)
The only issue remaining it that we would need to rebuild a version every update of the vesc firmware if we want to keep it up to date…
@b264 I see that you forked the bldc github, do you intend to work on a real open source/community managed fork of the firmware as you did for the vesc tool? Having this setting configurable would be nice, but i don’t think it’s really on the feature list benjamin is working on
