2005 Silverado Installing ethanol content sensor

[Supercharged111]

I found a file with the same os number and same year just with flex fuel enabled. I might give it a shot and if it doesn’t work i can always go back. Thank you for answering my questions. I’m planning on adding boost and just looking for a little flexibility with fuel options.

This requires a full flash, not a simple flick of the switch or mere segment swap. It has been done on LS1Tech though. I was initially thinking LS1b.

But the GenIV stuff is similarly simple.
