Hi,
I would like infos about sierra 6.2 at4, some are flexfuel, some not, so how to flex it?
Will i need alky sensors, bigger injectors, pressure regulator...?

I don’t believe any of the L87’s are flex fuel from factory. I could be wrong though.
You would need to make sure your ECU is flex compatible, do you have any flex fuel settings in the tune file?
The newest ECU designs haven't even had a fuel composition input. On top of that, some of the newest ECUs don't even have flex fuel software logic in them anymore, so this is going to be tricky.
I have a tune file from a 19 Denali pickup that has flex fuel enabled. Virtual sensor. Havent messed with converting it to a flex sensor or put any ethanol in it.
L87 are not flex fuel and it cannot be turned on in the tune and pinned like previous Gen V E92/E92A vehicles
Yep same as the E99 in the c8 and Zr1
