I'm thinking - "Gee, it's failing". Rather than have a setting that people cannot
use w/out triggering a failure, why not make 80% the 100% setting?

It really sounds like 100% is the "theoretical maximum", which cannot
reliably (key word) be used in the real world. What's the point?

I'm voting with my wallet, thank you.

caveat emptor
Rather than make a different JBD for every version of the DME software BMW releases they made one version with an adjustment range. For most newer DME versions anything over 75-80% will throw a code. So for those of you, that setting IS the "maximum effect". I've actually asked BMS to just rescale it so that the current 75% is the new 100% as I think it would make things less confusing for customers. But according to BMS some of the older BMW DME versions can use the 100% setting so they've been reluctant to nerf their power potential just for the sake of marketing.
