I'm in a little bit of a conundrum here. I've assembled a 5.3 engine that is identical to a LMF. Same cam, heads, intake, injectors, etc.
Because of my manual transmission and several other issues, I'm starting with a LS3 operating system. I'll need to copy the tables over by hand from a LMF tune.
Trouble is, there's no LMF tunes in the repository! The LMF was only found in the 2010-2014 Express vans with all-wheel-drive, which makes it a rather rare beast. I don't see many vans around anyway, and trying to find one equipped with a LMF would be looking for a needle in a haystack. Then there'd be the question whether a random stranger would let me plug into their obd2 port...
What route would you suggest to find this particular tune?
