Deatschwerks Developing EcoBoost Injectors In Time For 2015 Mustang

Looks like an auxiliary PI system.
Really is the best solution. Doesn't break the bank.

Then again if you look at that paper I posted above, do we really need any as long as the E is kept low thus keeping fuel volume in check? Look at the results of the testing with E-85 at 14%

Here's another study Ford was involved with...

Assuming that data is correct and my experiences so far lead me to believe it is, with that knock resistance shouldn't I be able to start moving target AFR's up during WOT? (I'm at .80 currently)

Wouldn't doing that help restore fuel headroom also?

At higher levels of E I start to see knock which I believe is due to the fuel pressure drop. It doesn't matter how much octane I have if I'm out of fuel.

As E comes down and volume is restored positive KR activity disappears and negative KR increases pretty dramatically, I actually see it at WOT.

Well, it'd reduce the work load on the system, as the demand drops. But that's of course a delicate balance...
You'd need to make sure your fuel and blend is fairly consistent, if you tune aggressively and with blending E.

So, lambda .80...That's what in E15 blend (isn't that your blend ratio?)? AFR of 11.5 or so? Seems healthy.
But I'm no expert.

I guess it depends on your goals. I saw you mention in another thread. Your goal is an 11 second car. I'll bet that's achievable spraying meth and blending gentle E and possibility running the OE system on the ragged edge.

But I'll bet you won't stop there. Becasue you'll end up wanting mo powah. And you'll end up having to find another solution anyway. Lol

Perhaps ajp can offer some thoughts.

Yup, E-15 now. Looking at those octane numbers E-10 may even be sufficient which would give me even more headroom.

I've pretty much got the blending process down so I'm not worried about that. Fill up with 93 to 85% on torques fuel gauge, then top off with corn....puts me right around 3 gals give or take.

Whether I will want more power remains to be seen, the car spanks pretty much everything that steps up unless it's a GTR or Shelby. I was untuned for a very long time and was quite content. 

For now I just want to make sure I wring every ounce of performance out of the stock setup and I don't want to waste money on WMI if I already have massive effective octane and can keep pressure in check at current, or even lower levels of E.


The research just leads me to believe we haven't exploited the benefits of directly injected corn yet.
