MM and NEU compatible?

Actually, I ran the neu with both. The Nue suffered from cogging as I described above, when run with the MM. As long as the truck was moving, it was fine. Once you stopped, getting started again was iffy. I tried everything too. Cap bank, gearing, timing, start power, etc. The cogging was there to stay.

Unfortunately, bdebde is right. I don't think that Castle will release that fix until some time after the MMM is released. I know that I wouldn't buy a MMM if my MMs worked with the Neu. Well, I'd buy one MMM, but nothing near the number of MMs that I have.
