Stock Tune Segment Swap

[eldplanko]

First post... noob question.

Looking for a stock tune for my 2016 LML for EFILive... did the TIS lookup for my vin on GM and figured out my segment part #s. I found one stock tune that has 7/8 matching segments (everything but system), and a separate that has the other one (system). Can I just segment swap the system segment from one into the other to build my stock file?

I've done it for others and they said it worked. Just make sure ALL the segments of the finished base file match what TIS calls for.

That's the plan... guess if it doesn't work I can always pay the $50

Segment swapped, EFI Live checksums all good. Is there anyway to confirm the EFI Live checksum matches the TIS CVN so I can be certain me “stock” files I downloaded off the net haven’t been tinkered with?
