Sorry, I should have made myself a little clearer, there was no chance I would get to this for at least few weeks from your original post. We are just trying to clear the backlog of things to finish off.
I will add that we are currently working on an E39 / E78 software change that will be critical to further progress in the tuning of these ECM's, that should make it to the next release, so the E78 hasn't been totally forgotten.
