Correct me if I'm wrong, but from my understanding, the KessV2/Alienware hardware is able to read the LML ECM as a binary file and they have then converted it to an editable format? (FYI - this is still a $10K proposition)
Some European software is out there that will allow you to edit the .bin file, however, you'll have to invest the R&D time into that (IE, make your maps, identify them, etc)..
Awesome that EFILive is allowing us to flash them at least.
