Flex fuel sensor

[Milkman83]

Who has added a physical flex fuel sensor? Which sensor did you use and where did you pin it in the ecu?
I’m looking to add one to my 13 Denali.

@iamdub did it but he's on hiatus for a while. His story starts about at the link below (and he provides detail links a few posts down from that):

Loving my E85 right now

I thought it was more of the fuel content sensor (or whatever its called) that told the ECM what duty cycle to run the injectors at, Not the O2 sensors? Edit: Flex Fuel Content Sensor is what its called.

Hey thanks again. That was exactly what I was looking for. I just did a dod delete with a gpi cam and my tuner wanted me to get a physical sensor before he turned flex fuel back on.

If you have links and or part #’s post em up please. I’ve got to do that to my 09 Esky to ensure GM’s current system of e85 tuning by exhaust gas only doesn’t have to guess as hard.
