E85 is AWESOME!

Here's a primer on current flex fuel tech in modern vehicles...

Great read. Thanks!

I would not personally play with E85 unless i could monitor fuel pressure; Each car will act different fuel pressure wise considering the blend could be different; As for how long it is beneficial, i do not know.

Look for the MSDS sheet of the brand you are using.

Speedway is 75% winter blend, 85% summer.

On the ride home tonight, the Big Girl rewarded me with a new peak torque reading...

353.7

FRP hit 2670 on that blast.

Boost @ 12PSI

She was very strong tonight, every WOT was well into the 300's, HP and torque.

Nice!

Wait. what?  Did you swap injectors to run E85??

Nope.

2013+ fuel system is a little beefier to begin with.

Hits AFRs just fine and FRP is still outstanding.

Lots of info in this thread if you're interested.

cool seems like a nice / easy way to pick up some added power. I guess the ECU recognizes the added octane and adds more timing for it. Is that where the added power comes from ? how do I log with an iphone5 ? I already have concerns about my FRP with my LMS tune due to high rpm hesitations. Mainly with hard downshifts, but I don't know what to do about it, or confirm that's whats going on.

DO NOT ADD E-85 IF YOU ARE ALREADY FRP CHALLENGED!

You need to get some data toys and log that FRP ASAP.

You should also cruise over to the unleashed vendor area and check out what Mr. Torrie's tune belted out on 91 octane. (hint...it doesn't run out of fuel)

It is a very enlightening thread.

I figured out how to use the graphing function in Torque, but I can't figure out how to get it to use two axis so I can compare FRP to boost, RPM, ETC. Whenever I choose FRP, the axis 2 option disappears. I will inquire with the Torque developer about this.

But since the graphing allows me to watch for dropouts I decided to push ahead. I figure I will keep pushing till I get a CEL or i see FRP fall.

I went and put in 6 gallons of E-85 and 11.24 of shell.

Usually I top off while the car runs but now that I understand Ford's "deductive refueling logic" I shut it down so I could watch what went on with fuel trims on restart.

Now I'm at E-29, 97.5 octane.

My peak FRP was down a bit at 2400.

Graphing showed a perfectly linear line, none of the dropouts that we've seen with the fuel challenged SHOs.

Get this.....28 degrees of timing advance @ WOT. I've never seen over 25 before.

Fuel trims were a little wild at first but within 5 minutes all was well. You would never know about crazy trims as the car ran perfectly while it made its adjustments. Based on what I saw this "deductive refueling logic" is functional in our (2013) cars from the factory. The description of how it works matches with my experiences exactly.

OK, so I am a little late to the data logging game...  That and I'm super old school, analog gauges on all my other cars... I've been doing hardware upgrades (exhaust DP's, IC next) but I did knuckle down and ordered the Nexus 7 and a mount for it, I'll be logging by later this week.  Do I need a Bluetooth adaptor or?  I'd love to mix in a few gallons of E85, 97 octaine sounds sweet 8)

Learning as I go ... I'm a little confused on on the E85 thing I've been reading up on it and have changed my mind and decided to give it a try .... especially at $2.69 a gallon . Last night before I installed the 3 Bar , t-stat and plugs I filled to a little over 3/4 with 91 . This morning after I loaded Torries 91 Tune I drove to a Kum n Go gas station that has E85 and topped it off with 4 gallons of E85. I only live about 3 miles from it.
Some posts are saying don't use E85 in the 13 SHO and others are Nuts over it.
The fuel inlet shows E85/20 so I'm thinking go for it , especially with it blended with 91 to raise the octane.
I have Torries 93 tune as well just not loaded ...
I'm not using Torque Pro yet ... waiting on my MX to get here .

Work with torrie to get some good data logs to make sure you're not running out of fuel, that's  your only concern, E85 takes 30% more fuel than regular gas and you're close to the limit of the stock fuel system with a tune already.

 

[SHOdded]

Hopefully, having a 2013 will work in his favor and give him some headroom over the 2010-12.  Torrie probably already knows, wink wink.

That's what I was thinking as I have read several posts on the forum stating that the fuel delivery system on the13+ is a little beefier.

I don't want  to mess with this too much until my MX comes in so I can run Torque Pro.

What should I be monitoring ?

I'll send Torrie an email and ask him what he has for an E85 blend .


Eventually my build plan will necessitate a modified pump system , possibly the one that 4DR has .

 

[FoMoCoSHO]

As much as I've been impressed by E-85 in my SHO, i would not use this tuned with out the guidance of Torrie.

He has indicated that 30% is the max but each car is different...so proceed with caution till you can generate some logs.

Thank you FoMoCoSHO , I am waiting for a reply from Torrie about this . I expect to hear from him tomorrow .

What Tune do you normally run ?

I am untuned so my fuel requirement is definitely less than yours.

Untuned at E-29%, I've had no issues which I believe is due to the beefier LPFP in the 2013's.

As soon as my cutout returns from PPE I will be using Mr Torrie for a datalog tune with E-85.

Just take it easy till he gets you tweaked and you should be safe.

 

[FoMoCoSHO]

I would love to see your AFR, FRP, and fuel trims with the current tune.

When my MX OBDII  adapter gets here Sometime  this week I'll be on a learning curve with Torque and I'll post it .

Hey 4DR, I've read that the EB uses Bosch fuel injection parts.

http://www.bosch-automotivetechnology.com/media/en/db_application/downloads/pdf/antrieb/de_5/Bosch_di_folder.pdf

Is any of this in our cars that you know of?

Because the specs about MAX pressures, types of fuel, etc is quite interesting.

This stuff will support 2900PSI and "worldwide qualities" fuel.

Apparently the Motronic ECU has torque based programming also

"Torque is used as the key criterion for implementing all
requirements. According to this criterion, the air-fuel
ratio is adjusted in such a way that the demanded
torque is provided as economically and cleanly as
possible. It also allows active driving safety systems
such as traction control and ESP® to intervene in the
engine torque.
Motronic can be used to control internal-combustion
engines
running on gasoline (port fuel or direct injec
-
tion), diesel, natural gas (CNG, liquid gas) or ethanol
as well as hybrid drives. Standardized communication
interfaces and data formats support networking with
all vehicle systems which influence the drivetrain. "
