had a quick question on updating a 2014 5.0 gt to e85, so I haven't messed a whole lot with fords and wondering if anyone can assist a bit
on adding 47lb injectors and going e85??
been doing some research but id just want to get some input from you guys as well. car is stock just wanting to update it a bit.
there is a thread devoted to flex fuel tuning with files you can use to help guide you, search bar is on the top left of the forum ;)
Thanks man gonna give that a shot
Top left? :DQuote:

Same timing? Typically decent gains can be found by shoving in more timing on a vehicle running E85.Quote:

No our cars don’t have an ethanol sensor. Only way to tell is by lambda.
Also to make the switch first change stoich AFR. I have mine at 8.85 and then depending on mode goto MAF and add 30-50% fueling. Drive and adjust as needed then you can start playing with timing. Gains on E85 N/A cars usually shine under the curve as you can ram more timing down low for that extra grunt off the line.
Meh, customers think E85 in their basic bolt Coyote makes it magically more powerful, so I give them what they ask for. I'm sick and tired of having to explain it to them.
MRRPMBRP is just confirming what a lot of us already knew.
Most all NA Coyotes hit the peak gains from timing advance before they hit the knock limit of 93 octane.
As hard as it is to find reliable E85 sources, I try to "encourage" my clients not to waste their time. If they really want it badly, I'll recommend a flex fuel tune if they are NA.
As for the boosted cars, I recommend E85 and a 93 tune so they can switch back and forth. Boost + E85 + Timing = win
Yep, maybe a little E85 laced with nitro would help power.Quote:
