EFI Live can be confusing at first, remember the search bar is your friend when it comes to finding parameters.
Load EFI Live tuner, scanner and scan and tune on your pc. Update them all before using. Update the firmware on the flashscan too. EFI Live is a PITA if everything isn't up to date.
First thing is SAVE a copy of the original file, it's essentially the stock tune with vats removed.
Then "save as" a copy and name it modded tune; this way you can have to backup file if you screw things up.
There's a lot to learn with EFI Live, it may seem overwhelming at first but just change one thing at a time and observe the results.
To turn off afm go to - engine operation-air fuel management-parameters-afm equipped and set to "no", then save the file.
Download the tune as calibration only, takes about 30 seconds. You only need to do a full flash if changing vats or other important OS data, a full flash takes 4-5 minutes. The cal on a Gen IV ecm is about 2 megabytes and the tcm almost as much; in comparison a Gen III PCM is just over 200 kilobytes.
Be sure the flashscan is plugged into the pc whenever working with the cal. If the flashscan is not plugged in many important parameters will not be displayed like os patches, in addition you won't be able to save changes. It can be frustrating at first.
When saving or downloading files be sure to select the correct controller or you will get nowhere. Your ecm is an E38 and your TCM is a T43.
Eventually you can save many tunes on the flashscan and take it with you abd download at will. A economy tune, crawl tune, etc.
BTW I talked to James at Adams today and he mentioned he never builds a ds out if phase, something about both joints having to move together. One of my 69' Camaro's had the experimental ds that was clocked 45 degrees out of phase, it always vibrated. I was told GM eventually replaced them with conventional shafts.
