State of E92 programming

I've had EFILive for quite some time, but when I got my Fifty, I originally didn't want to mess with the programming due to waranty, and later read that - at the time - the ECM locking prevented reprogramming. I was wondering what the current status is (the feature overview has a checkmark for ECM flashing), and whether there are some nice how-tos on what one can do to possibly optimize the parameters (back then, used a wideband O2 & the detailed document on how to do a speed-density programming for my LS1).

Thanks!

Sadly if your doing a swap and require VATS deletion you can only get a Calz file, but only from someone on this forum and only if you can somehow get anyone to actually reply. IMO, seems like EFI Live has gone crickets on development and further support (what little there ever was) on any Gas stuff.
