I don't know that there are any new EM diagrams out for AH2 yet but Badboy posted a number of them for AH1, you may want to do a search on that (by his name or "EM diagram"). I know I have quite a few for AH1 but I'm not sure how relevant they are anymore and they only account for very specific conditions (ie, specific weight and altitude).
There hasn't been a lot of AH2 data out there yet, the aircraft are still changing a bit and not all have had some of the remodeling that is likely expected (some have).
