We need to keep on this and let others know about these problems. That way people will buy other brands if Bafang doesn't help us with this.My Canbus Biktrix Ultra Beast is ok to ride on the beach but on the road it has too much power in assist one. I cant wait until the canbus is cracked so i can smooth out some of the settings.
Once they come out with something or a way for me to update my M620 firmware i will buy the BESST tool and modify. I was watching a youtube video and it looks like a PITA to use.
The BESST tool requires a dealer connection to Bafang to authenticate before you are allowed access to a VERY limited number of parameters. So yes thats the programmer no you can't expect to get much of anything out of it unless you are a Bafang dealer, and even then you can kiss goodbye most of the things available in the UART motors.
Bear in mind that the USA is a teeny piece of Bafang's business, and the DIY market where people want to dig into the motors is a sliver of that. Bafang has *never* been happy about anyone programming their motors... ever. This is their way of locking people out for good. Don't expect it to change unless its a total aftermarket effort.We need to keep on this and let others know about these problems.

Teeny part of their business, yes, certainly. The bigger story though, is the mid drive stuff we're talking about is mostly illegal anywhere but the US. Consider the market for 100nm plus motors outside the US. How many Ultra M620's do you think might be sold in Japan, or Europe? That's the "teeny" market!Bear in mind that the USA is a teeny piece of Bafang's business, and the DIY market where people want to dig into the motors is a sliver of that.

One solution may be though a little expensive and I'm not absolutely sure can be done by just replacing the controller is to get an X1 controller from Watt Wagon.I can't say enough about this new ultra. I hate to ride the bike. The programing is terrible it's so jerky.
Have you tried asking Anna @ Green Bike Kit?An X1 controller is a possible solution. If they don't have something that fits a Canbus motor they surely will very soon.
An easy right-now solution would be to simply swap the motor while they're still available in UART: https://www.greenbikekit.com/bafang...otor-parts/g51-m620-ultra-barebone-motor.html
It is possible (nobody knew last time I asked) that the UART controller would work on a Canbus motor: https://www.greenbikekit.com/bafang...-parts/bafang-ultra-motor-controller-52v.html
It would be great if somebody could confirm whether or not that last option is possible as it is by far the cheapest. If it was I'd probably pick up 1/2 dozen of them to put on a shelf for the future.
I have no doubt the Archon X1 is fantastic and greatly improves the Ultra. However, a great many of the most common complaints of the stock Ultra programming have absolutely nothing to do with its sampling frequency. For years these things could be fixed (tuned to taste), greatly improving the feel of the motor for those who wanted to put forth the effort--basically for free. So while the X1 is a solution and probably a very nice upgrade, don't be surprised if somebody who just wants to fix something he thought he could fix for free is still quite angry after being told the X1 is the only solution he should bother with.If you are going to spend any money, get controller upgrade (and/or motor) from Watt Wagons. Don't waste your money buying an Ultra from Luna (or anyone else). I highly doubt you'd be able to program it to your satisfaction (due to the sampling frequency issue). The Archon X1 might seem like a pricey upgrade but it's the best money I spent during the pandemic, my Frey CC being a close second but only because the Archon X1 made it complete. YMMV with the Juggernaut.
