Upgraded HPFP on its way!

I would tend to agree.  The cut out will allow the turbos to spool up faster and the engine wind out quicker with the same tune.

Keep in mind Ford said hell no about anything above E10.

Then they quietly backtracked and said E-15 is fine.

We know they have tested the EB at 30% blends.

We also know they have tested E85@100% + port injected 93

My ECM has had no issues dealing with the blends I have ran to date.

Do the math.

I would say no to the Tune having to be modified  to use 4DR's cutout . He ran it in his Flex for How long .... with no mention of this issue and you know  he monitors all of the variables closely .

Maybe He'll chime in and educate us since we don't know what his tune was and we're not tuners... We both need to know if anything needs to be done both for engine safety and performance. 

Likely FoMoCoSHO is right and the ECU can deal with it

So FoMo, your car is adding timing on its own in the 26° range or are you running a tune for that?  Im not getting any more out of it than i normally see when going WOT, but when cruising and pulling hills its adds a ton.
The one thing I have noticed in my truck when logging it takes longer for the fuel to catch up and hit the commanded AFR but it is capable of doing it at any blend I've ran.

I've noticed that I'm seeing 26+ in 1st @ WOT, 20-22 in higher gears.

I'm still trying to figure out the logging on this new software, it polls data so fast I may miss peaks on the gauge screen.

No tune.

i have seen no lag in AFR except when I'm running a new blend percentage, the lag can be felt in throttle response until the ECM learns the new trims. If I return to a previously ran blend, that lag is pretty much non existent.

New times in the drag racing results section.
