2015 F150 Ecoboost FIXED!

[wwest]

Personally I cannot believe/accept the possibility that the ECU calls for boost while the throttle plate remains partially closed. I have always believed that the Ecoboost's design uniqueness comes from simply using boost as a means of extending the engine power generation once N/A intake flow is exhausted.


On the other hand if we assume that the CAC offers a bit of flow restriction in "high cruise" then the turboes might well be spooled up in order to maintain atmospheric pressure at the CAC outlet.


Plus that would help to explain the condensation issue.


If there is a pressure drop across the CAC during "high cruise", throttle almost, but not fully open, then the formation of condensate while "off-boost" becomes perfectly understandable.


Furthermore I am of the understanding that the 2015 F150 is making use of airflow vanes/shutters to prevent the cooling of CAC crossflow air during cruise mode, or "off boost" mode, whatever.

I couldn't agree more! I knew that was the problem! Now if only all automotive manufacturers would exercise this same knowledge the automotive world would be perfect.

Do what?

Do you mean "fixed" as in "I got my dog fixed"?

"Sounds like too much intake and not enough exhaust!"

I thought it may be too much exhaust!

WTF? Cabin fever?

Sounds like too much intake and not enough exhaust ! I'm experiencing the same issue with my stomach !!!

Just kidding, but what your discussing is definately over my head !

Are you asking a question, trying to tell us how you fixed something, or?
