LS1 Flex Fuel Tuing
Hi, Ive got a 2003 Holden VY Ls1 with cable throttle that i will be writing a 2002 Yukon file to with flex enabled.
Ive done plenty of flex tunes using the later e38 pcms hence my question about the LS1 Pcm. I usually use the PE EQ ratio multiplier to tune my fuel on PE for E85 and the rest of the closed loop is left up to the factory parameters which is pretty good. This File Im going to use does not have a PE EQ ratio multiplier like the e38 does. So how do I adjust the WOT fuelling? Do I just use the Open Loop EQ ratio for alcohol tables?
Thanks Guys

Nobody ever tuned a 5.3 or 5.7 with factory flexible fuel before?
