Flex fuel/Ehanol sensor retrofit?

[jkampf87]

Hey all i have a procharger kit on order here for my 07 silverado classic. i have the L59 flex fuel motor. 

I believe mine has the virtual sensor set up which reads the ethanol content on the o2 sensors.  dont see any content sensor after my fuel tank... unless its well hidden ontop of the tank?

looking for some insight on this. id like to run e85 on my supercharger set up. from looking around the virtural sensor set up isnt ideal. so is there a way i can run an ac delco content sensor on this? i see the option on my HP tuner so there must be a way? or am i stuck with this virtural sensor set up?

If the computer is a flex fuel and you can set it to sensor in the calibration you should be able to wire it into the computer and make it work.

sounds like what i need, any write ups on this?

Maybe somewhere, I've never done it on that computer. I'm sure you can track down the wire diagram pretty easy to see were it needs power/ground/signal.

 

I've done it on a E38 computer which is much different.

Alright believe I found some info. Looks like I want to wire in my Vout from sensor to pin 56 on my ECM then mess with a few things on my tune file... All parts on order except the fuel filter, here we go
