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.

Is the vehicle factory flex fuel? Or a flex fuel bin without the hardware?Originally Posted by corvettechronicles
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.
