I also have the flex tune since it came out. Love it, data logged a couple times and everything has always looked good. Switched back and forth between 93 and e85 a few times. No issues what so ever. On colder mornings it might crank a couple extra times before it starts. Never had a no start. I will also be running 93 or mostly 93 for the winter.

I love mine. Do it. Only downside is gas mileage takes a shit and not many of those stations around yet, but when you floor it with a full tank of flex fuel you will have a smile on that face :)


Ps how do I read the data logs? And what do I look for to see if it's running good? Lastly how can I make the nguage tell me when it has adjusted? I have just been watching afr until it drops to 10.2 or so

just installed mine yesterday, along with SP headers and PMAS intake...trying to run this 93 out to fill up with the Korn. is it absolutely necessary to datalog or is that just if you have an issue? using the nguage

yes! just go to the alcohol data on your gauge and look to see when the content goes up from the 93 content. usually get it under 5 miles and fill it up e85 and look at the content on your gauge.

When you fill it , hold your rpm around 2k , you will watch the afr on your dash go from 14 to around 10. Then enjoy the new torque

Installed my flex fuel tune last night. Currently running 93 octane. I also have pedalmax and just for the kicks I turned it off to see the difference with just the tune. It was like pedalmax was still on, no throttle lag and the car pulls really smooth on 3rd and fourth gear now. I am loving this tune so far. I also don't have the problems people are having with the ford racing tune such as rev hang. The car engine brakes whenever needed.

Nice. A pedal max really isn't needed with a tune

What kind of mileage drop did you see going to the flex fuel? I am more concerned with the range, I wish it had a bigger gas tank!
