AFAIK , Ecutek maps are encrypted at the application level. So a tuners map and settings are safely secured and tied to the site licence (dont hold me to that however).

Once the tuner has come to the point where he/she is happy with the tune, the settings are reassembled back into the proper ROM format for flashing.

You could reverse the ROM and then do stuff to it from that angle.. sure..

Just depends on what you want to do really.
