F-150 with Ecoboost

[Frank Lee]

You can run blends in there. My '94 F150 loves the stuff and of course it isn't even a flex-fuel vehicle.

I'd be afraid of damaging something with all the alcohol - at least, that's what they say will happen. alcohol will eat the seals and gaskets in the fuel system...
of course if you're using in a 1994 model without problems, I may have to try it one day.

Came back a different way from my favorite restaurant today due to construction - the truck automatically downshifted to 2nd gear to keep the speed down, 4,000 RPM at 40 MPH and i still had to use the brakes to keep from running away.

That hill has awful fuel economy going down, and I'm afraid to think of what it is going up.

4k rpm, when.you're off the pedal, should be on dfco... I thought pretty much everything had dfco at this point?

The only reference to a fuel cutoff in the manual is that it will shut off the fuel pump in the event of an accident.

Who's "they"?

That's what the manual for my Focus said too. But when you're on the highway and let off the accelerator you can "feel" that it is in DFCO.

I like boost I tried to get this for the possibility of snow plowing, but the truck has electric power steering which means you can't put a snow plow on it. It overloads the electrical drive system.

they ran a 24 hour test for advertising, but never said what the mpg was at WOT

would like to see them re run the testing with it "low" on coolant and oil ECT, and see how it fares.

With low oil - I'd assume the turbos or pistons (Which are cooled with oil jets from the bottom) would fail in fairly short order, so it wouldn't matter what the fuel economy was.

Low coolant? That's an interesting one - the engine would de-rate and eventually switch to an air cooled alternating cylinder mode. It would probably fuel like crazy to keep the cylinder temps down.

now you all have me curious - i'm going to go climb a hill with the scantool attached (not the instrument panel cluster) and see what kind of numbers it has for fuel economy

[p38fln]

Ok, I climbed the hill and accelerated on the hill to see what it did - and i can also confirm that it has no DFCO, when going back down the hill, the higher the rpms went, the higher the fuel burn rate went - up to 1 GPH at 3,000 RPM. I couldn't find anywhere that was long enough, steep enough, or deserted enough to see what its real maximum fuel rate was - and 26.9 GPH is really sucking it down as it is!

It appears MPG at WOT at 60 MPH would be 2.23 MPG - probably less

Maximum fuel burn rate - 26.9 GPH
Maximum boost pressure - 14.1 PSI
Maximum fuel rail pressure - 1,975.4 PSI
Maximum spark advance - +40.00°
Minimum spark advance - -7.50°
Avg spark advance -- 19.03°
Maximum intake camshaft angle -- 50.4°
Minimum intake camshaft angle -- -1.0°
Average intake camshaft angle -- 14.0°
(I forgot to turn on logging on the exhaust camshaft angle)

Air fuel ratio - Max -- 29.28:1
Air fuel ratio - Min -- 11.05:1
Air fuel ratio - Avg -- 16.70:1
(Not sure how accurate this part is - the highest LAMBDA value recorded was 1.050:1 and the lowest was 0.749:1, with an average of 0.983:1)
