Well, I have E-85 very close to my house and I rarely travel.
I would like to do some experimentation as I've had some good results stock with E-85, my current blend is about 23.5 % @ 96.5 octane.
I have been monitoring with Torque, AFR commanded and measured seems stable but I know it will work better if stoich is adjusted to the blend I am running. Using Torque and an ethanol calculator I am able to keep the blend very close to where I want.
I am seeing 2600-2700 PSI peak on the fuel rail and I've not seen any dropouts in the logs like is being seen with some of the 2013's that have been tuned. (not yours)
I am going to figure out how to enable the graphing feature and log only FRP so I get the most data possible. I am confused with my results as they seem contrary to what the conventional wisdom about the Eco fuel system is. The 2013's are different, the LPFP is variable and maxes out 10 PSI higher than gen 4.1. I have been documenting my experiences in 4dr's E-85 is awesome thread if you are interested.
Would you be able to help me with my endeavor? I plan to start my build as soon as this miserable winter ends. I currently have a typhoon on the car and I have catted downpipes and 4dr's boost actuated cutout ready to be installed at the same time.
I do have an AWD dyno in my area and I would be happy to do any logging necessary to get it dialed in.
