Livernois Tune Madness on "Winter Blend"

[FoMoCoSHO]

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

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.

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

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

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

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.

Is it still happening or was it a one time deal?

Did it all the time with a tune.  Fine with stock and yes plugs were re-gapped and all that.  Don't have the car anymore.  Unfortunately Livernois wasn't of much help in solving it.

Almost seemed like your tranny was slipping too...

 

[jmr061]

Yeah and you can't hear it but it would "pop" too.

 

[JMR76]

Yep, that's what mine would do.  Just started doing that in the colder PA weather.

Jason didnt you have a Corsa exhaust back then?and the other member also,and lots of oil inside the spark plug wells does not help your issues,Btw the OP stated the pop is coming from his Corsa exhaust,find it quite odd ummm,think you need to change your plugs more often and check for any visible signs of oil inside the spark plug wells for a peace of mind,now if your car has less than 10k dont even share your opinion in the matter.  Z

All this talk about plugs, I can't wait to see the plug service recommendations for the new Raptor and GT. I seriously doubt its every 15k.

BTW, last time I checked this is a public forum so Jason is welcome to share his opinion as is everyone else.

I'M actually waiting for Jasons quote and you are correct FoMoCoSHO, Yes sir!!

I thought we suppose to keep it real and not outside the scope,i'm done here.  Z

I was relating what I had experienced to the OP as it may be the same/similar issue which Livernois states that have never heard of...

If it is the same issue that would be incorrect as I have the emails back and forth with Livernois about the issue I was experiencing.  It doesn't matter how many miles are on the car which I traded in with 31k and it still had the same issue with the Livernois tune but was fine with the stock tuning.  I wasn't too concerned with the issue since I didn't drive around with my foot going to the floor all the time.  I just left it alone. 

The OP can watch the video and tell me if he feels it is a similar issue.  Didn't matter if it was summer or winter blend fuel either.

Don't have that issue with the 16 Sport I have now which I do have a Livernois tune in.

Was that video done in the cold? How cold and how long did it warm up?

Looks like a cold transmission not allowing a shift to me...just a guess, but I've seen other videos just like this from guys who get in car after a brief warmup thinking it's ok to go WOT already.

The engine was was warmed up as you can see by the coolant temp gauge.  That video is from 2.5 years ago.  Didn't matter if it was warm or not.  It did it ALL the time with the tune in it.

Couldn't really tell, not as familiar with the 13+ gauge setup. I can let mine warm up for 15 minutes to get the coolant to operating temps...but, it takes another 20+ minutes of driving to get the trans up to about 130* in temps that are below freezing. The trans warms very slow and caution should be taken to avoid any kind of WOT pulls before it is up to a decent temp.

I havent noticed cool trans temps to be a problem...once my coolant is above 170ish i go wot when im out testing..ive never seen anything like jmr car

Shonuup does your car do that when cold also?

I never get on my car when the trans temp is under 120-130 range. So I would have no idea if my car does that. I do notice slower shifting when the trans is not up to temps in normal driving though.
