i have a 2014 S7 4.0t
There are flex fuel tables in the tune file. I am wondering if anyone has or can point me in the right direction to enable this feature.

No hardware.
I am trying to understand the logic for it as they don't have an enable mode for it. I found values for the fuel pressure increase based on fuel temperature, then it will modify or use SF which is secondary fuel like ethanol. I am going to test my theory out this week.
Not sure if this helps but I have an S6 with ethanol sensor wired into OBD port just like DS1, but Hptuners does not read it. I cant find anywhere on the tune where I can enable a flex fuel sensor, like ive seen on some videos for GM cars. Let me know if you do get it working, It seems like it does have everything else you would need.
Any update? can anyone reach out to support? we need support for ethanol sensor and addition of 4 bar map and ability to log wgdc. Ive tried asking support maybe if someone else reaches out they will consider it more and realize the demand
In order to have the ECU working with the Ethanol sensor it need to be wired directly to it, for this you need to know the specific location for the pin on the conector and then do the programing required to let the ECU know its there.
