Not sure the best way to go about converting to a Flex Fuel Tune as I am running manual transmission.

I am currently running the following:

2002 Chevrolet Camaro Z28, 5.7 L, V8, GM_P01

P01, ECM, GM Gen3 V8, 4.3L V6

Hardware: P01, GM Gen3 V8, 4.3L V6

OS: 12212156


I want to install a flex fuel sensor so I can run E85. I also plan on running a pro charger also. I found a tune file from Sloppy Mechanics wiki that has flex fuel enabled, but it has an automatic transmission and is not the same operating system. The segment swapper is greyed out when I try to swap transmissions.

Does anyone have any information on this or how I can go about converting to flex fuel with my ECM? Would it still work having an automatic transmission in the tune even though I have a T56 Magnum?
