I have a 2001 LQ4. I have 2 sets of flex fuel injectors.
Flex fuel 2002-07 5.3L 12580426
Flex Fuel 2007-9 5.3L 12594512
The data for the 12580426 is pretty easy to get.
I pulled up a tune from the repository from a 2007 Tahoe Flex fuel and it has the option to switch from VAC to MAP on offset select. The MAP table is zeroed out and I don't see a VAC table anywhere.
Anybody know where to find that?
