I like ECUTune or ECUTweak, since it's a sibling app to ECUFlash.
BTW, I'm still in this. I've been working on refactoring some of the stuff to make the application RamTune-aware and so that contributions to the code from the community will be easier. Is the source control system back up? Do we still have access to the original repository? If not, can I vote for Subversion as our next source-control manager?
I'm sure we'll have plenty of time to talk about all of this in the near future. Glad to see the site come back.
