As I wrote, I have a regen lever:) this allows me to program (pretty much) any regen power that I want. Conditions don't really matter, …..   

Thanks for the explanation.
I hadn’t realized this was possible.

Hello,
you're right, the MBB overwrites some settings (at startup, or constantly, I don't know), for example the custom ride mode, like you said. Therefore, I can not use the regen-braking in the custom mode, only in sport mode (that's on a 2013.. it only has a switch with the two modes).

Here is a video that I made about fitting a regen brake lever. I don't know if it helps much:)

Yes, I came across that in my searches. Good video. I expect that once I have the softare, that'll save me a good bit of time. From the look of that tank and dash, that bike is at least several years older than mine. Since Sevcon had changed hands twice from when your bike would have been built and Zero has obviously been locking down things like their MMB over the years, I was hoping to find someone who had modded a 2020+ bike.

Are you able to download your DCF file with your DVT software?

Oh, and an older note: https://www.motorbiscuit.com/the-verge-ts-is-an-electric-motorcycle-with-only-one-brake/

Yes, I think I can download DCF files. I think I remember doing that, before changing anything

So after having to wait over a month to get my cable, the newest software is NOTHING -- and likely also the result of the latest revisions to the controller firmware -- like the images, videos, and instructions posted about past models. In some ways, the new stuff is simpler. I did discover a few interesting things though.

For some reason, Zero is writing the top speed values for all drive profiles through the SDO protocol at startup. So you can't change those and have the changes stick. I don't really have a need to go faster than 106, but if I ever change my mind, I might make a little PIC board to simply send the one SDO command a few seconds after startup. It's pretty easy to extract the necessary commands now that I have the software.

Also, Zero leveraged the footbrake input as an RPDO through the canbus, so that has to be deactivated if one wants to use a custom regen lever anymore. And if you do that, you'll want to set your max brake torque to whatever you want in both the drive 1 (eco mode) and baseline (sport) profiles. The regen lever will at least work the way you want for those profiles. In custom, however, the MBB overwrites the brake % at startup or if you try to manipulate it through the app, so it'll max at 8.5%. Your regen lever in custom will be no more powerful than the stock max regen.

Otherwise, smooth sailing. I really don't understand why they don't sell it with adjustable regen in the first place, even if nothing more than a sales gimmick. It's practically free to implement.

That's annoying, one of the few things I'd want to change software wise is the top speed as my bike is one of the 11kW models limited to 86mph.
