I'm not sure if this is old news or not but I saw that Ford Racing released a stand alone controller for the 3.5L Ecoboost. It's advertised as only working with their crate engine though since it needs a return-type fuel system, although I assume that's just to feed the DI high pressure pump, so it shouldn't be hard to plumb a junk yard engine to work with it. I'm wondering how popular these will be as swaps going forward.

FWIW, they don't run overly rich. No more than a PFI N/A motor most of the time.
The issue is something else. Not that it's better, but it's not too much fuel.
There is some discussion that it may be partly due to the amount of time the small motor in a big truck spends in positive manifold pressure, and because of this the PCV system cannot remove blow-by fuel vapors effectively. Any input on this theory?

That would actually make a lot of sense. I wonder if these would do better given some kind of vacuum pump to pull air through the crankcase while it's in boost (and probably dump it into the intake upstream of the turbos)?

The system is plumbed to push air thought under boost. It's not as good as a N/A system, but it does work pretty well.

Ok, so that's not it likely.
My Dad's Escape Ecoboost just dumped all the oil and threw a rod at around 50k miles. Kinda random.
A lot of small Euro turbo engines spend most of their lives under boost and don't have dilution problems. After plumbing a boost gauge into my Volvo it is eye opening. Any throttle at all leads to 2-8psi boost.
VW put less-powerful 1.8t engines in A6s overseas. That's almost mean

1.6 or 2.0?
I think it's the 2.0
They are covering a new engine under warranty btw.
