os 2020005 segment swap help

[BlockerBoy]

100% completely new to this but was hoping to be able to do a segment swap for 4l80. I just installed the 4l80 and was hoping to be able to swap a stock file until I could get the truck to the tuner to have him make some tweaks. I've read that I need to do a segment swap using a tune with the same OS but have searched and searched and downloaded numerous files. I'm having no luck finding a file in the tune repository w an OS 2020005 match. Someone please point me in the right direction. Truck is a 2002 Sierra w a 6.0 swap and have everything to install lsa supercharger but was getting the 4l80 and other supporting mods squared away first.

Looks like the computer you have was probably tuned with EFI Live first because that is modded/upgraded operating system already.

Segment swaps work with factory OS's.

Somebody with other software might be able to make it a 4L80e file but I don't think you will have any luck with HP Tuners by yourself.

And here I was thinking it would be somewhat easy w the segment swap

Better off to find a fresh base file, segment swap that, then upgrade to a HPTuners Enhanced OS for the PCM. The OS in question is an EFILive COS, so you won't be able to find a segment to swap in via HPTuners, you have to start with a non-COS/Enhanced OS and segment swap that.
