Livernois Tune Madness on "Winter Blend"

[FoMoCoSHO]

To clarify OP stated he is running E-0 which apparently WI has lots of.

To the OP was curious to know if you ever got a chance to properly tighten that rear #3 spark plug under the charge pipe figuring your issues seemingly started right after installing the plugs,just trying to troubleshoot and help ya out.  Z    http://www.ecoboostperformanceforum.com/index.php/topic,4587.msg72383.html#msg72383

I would definitely recheck all the plugs too see what they look like.  Did he also state that also his issue started after mixing E85.  If so I would find away to check fuel pressure on the lpfp.  The E85 could of damaged it.

Low pressure pump is a non issue

Doubt the e85 damaged it....just curious why u would think that?....the fuel filler says e0-e15 because the high pressure pump really cant support more E as far as ford thinks, with their saftey net in mind.im pretty sure all the fuel system has been upgraded to handle various fuels...fomoco posted something about that a while back

I think on a stock tune you pretty much have 2000 psi at the rail at wot all the time so everyone running a 3 bar tune on pure gas would have fuel pressure below what ford preferred....

Its not a ffv car because the pump wouldnt have the output not because the components can't handle ethanol fuels

Are you running E0, E10, E15, or ..., AJ?

My sunoco says E10

I think I saw you mention you're in PA, I'm in Lower Bucks, are you close? I guess our stations use similar fuel if you are, maybe also even if we're not close

Pittsburgh..i know nothing of lower bucks lol....

And happy 1000th post to me...i am a big shot now and i have arrived

Being in PA, you are in one of the "boutique" states that features an even lower RVP than the Fed demands.

The Ecoboost was initially designed as a FFV. On E-85 it was rated at 415/400. I suspect they axed the FFV part cause they knew the tuners would try to exploit this and they were uncomfortable because they knew they would run out of HPFP very quickly above those levels. All the hardware is Bosch that is rated for E-85. Rated for hardware robustness that is, not the insane amount of HP some of us want to make.

Hhmm i wonder how i am able to run so much boost with no knock in 12 degree temps...maybe its all the logging i do with pids...or maybe im just lucky and my car is a freak

[FoMoCoSHO]

For us E-85 guys, I believe running E20-E30 and reducing enrichment to get volume back is the way to go. All the benefits of E-85 without the extra strain that straight E-85 would cause

Ford agrees...

"Reduced enrichment. Enrichment of the fuel mixture at high-speed, high-load conditions is currently used to reduce exhaust temperature to avoid damage to engine or emissions aftertreatment components. However, enrichment also degrades thermal efficiency. Increased ethanol content enables improved efficiency by reducing or eliminating the need for fuel enrichment."

Yep A great idea if you are into mixing E

Slightly more spark advance possible for a similar boost when compared to e0 gas and at your typical 3 bar tunes which run 13-15 psi it wouldnt overly tax the fuel system.

To optimize the tune i would rescale and add some fuel to the curve to offset the higher fuel volume demand for the specific Ethanol concentration to keep fuel trims in check....or just let the 02 sensors take over and add fuel as they see fit as long as ethanol concentration isnt too high and or boost isnt too high since the 02's are limited in how much they can add and pull....i wouldnt do that but it can be done

I have plenty of logs with pid's of fuel rail pressure showing there is plenty of fuel pressure at 18 psi boost above 4k rpms.....so that tells me at 15psi with e20-30 would be no problem...but i pull all this through comprehensive  datalogging so that may be a useless to some of you and i wouldnt put alot of stock in what the cars sensors are telling you

Would you possibly describe this issue as a short lived sudden miss?

This is what mine did when I had it:  https://youtu.be/ucgwkBqCxkc

watch around 40 MPH...it miss fires and redlines...never did solve the issue.
