#167 of 276 Ego Boost,NOT
Feb 12, 2012 (7:33 am)
Well after owning the F150 with ecoboost and giving FORD the benefit of the doubt. I was sadly let down and my apologies to all! A month ago the engine started shutting down and I would shut key off and restart and may be ok a day or two.Took to the dealer three weeks ago and they said they couldn't find any thing wrong and that the factory was aware of the problem! Well on 02/06/2012 it just quit running! I had a flatbed tow it to the dealer I purchased it from.After five days of being there I am now told that they have NO FIX for this! Even if they think they have it fixed I am afraid to go anywhere when and if I get it back! I don't think the owner of ALBANY FORD IN ALBANY CA. would like to be stranded on the bay bridge with his family to get run over by a semi! They expect me to let them throw parts at it till the problem resolves itself. I should have kept my 1997 dodge ram that never let me down. I will proceed with the California Lemon Law if the dealer doesn't do the right thing, Money back or new identical truck. PLEASE POST ANY PROBLEMS THAT ANY OF YOU HAVE HAD SO I KNOW I AM NOT THE ONLY ONE!!

My suspicion would be a "stalled" turbine, doesn't turn/spin freely, from HEAT expansion and thereby blocking the exhaust flow. Have the (St,d)ealer disable the turboes, "wire" the wastegate(s) open, and see if the problem still repeats.

I have the EXACT same problem. Now 2 of us. Just picked up after 5 days at Ford with the same out come . This is so Dangerous. I'm so sick of it . On the 3rd day it wouldn't start I used the lock unlock and it started next day 5 or six times , next day turned off going 70 on highway and almost got in a wreck . 5 days at the Ford shop . I was asked to pick up . I also wish I just kept my trade in. I hope no one has to get killed for them to just give us another truck . F 150 ecco. Just 500 miles and I'm sick of dealing with. When I first complained to the dealer after just 200 miles , I was asked to just jump it. WOW Carrollton Texas

With the EcoBoost/TwinForce design Ford is faced with basically the same problem that Boeing was with the early 727's, turboes take a LONG time to spin up. Boeing solved their problem by advising the 727 pilots to always keep the engines "spooled up", partial throttle, on the final approach leg.
The long time constant, spool up/down time, of turboes makes it extremely hard to solve that control equation. My guess is that they will eventually need to find a way to throttle the boost on the output side of the turbo rather than just using the wastegate as "throttle".
F-150 forums throughout the internet are indicating serious EcoBoost problems.
And now we have the new Explorer with an EcoBoost I4 proving.....interesting...

i want to order a 2013 platium 5.0 does anyone know what real world mpg is and also towing mpg . has anyone heard what changes may come for 2013.
#173 of 276 towing a 2012 f150 4x4 ecoboost

Has anyone set there 2012 f150 4x4 ecoboost up to be towed 4wheel down? if you have what did you have to do for wiring the brake and tail lights to run off the motorhome and not damage the f150 systems?

The stalling is most likely the ECU and TCU issue as indicated on forums, which are a vastly superior source on the likely problems than wwest, who is an inferior source to the back of a ketchup bottle on the topic of turbocharging.
Turbos take milliseconds to spool up. You're comparing a 10cm turbine wheel to a 100cm multi-stage turbine? producing 20,000 lbs of thrust? moving a 200,000 lb aircraft? first tested almost 50 years ago?... This is logical to you? That's painful. and indicative of just how well you think things through on this matter. There's concept... and then there's SCALE. You're off by several orders of magnitude, but to you, it's the same thing...
As if you were capable of sound logic , and as if every automaker hasn't already perfected turbocharged induction in various models.
(and they ALL already have blowoff valves and DO regulate on the output side of the turbo)
(and the turbos will be spooled 100% of the time while towing, and on light boost at all times except going downhill. Towing is more than enough load to burn the fuel which spins the turbines post-combustion)
You're an N/A purist on a smear campaign that failed before it started. Autos are headed this direction.
You admitted that all these theories about turbo operation are guesses, and you keep inventing ways to 'prove' turbines are unproven technology in autos.
The only reason I most likely won't dignify you with another response for some time is for the same reason all the other knowledgeable people dropped off; it's just too exhausting to try to convince the truly ignorant of a fact.
Well, wwest clearly has more argumentative stamina than the knowledgeable people who have posted on this thread, but cannot be convinced of fact for the sake of his fantasy world where his 'guesses' are correct to save his life.
The difference between genius and stupidity is that genius has its limits.
(and no, you do not get to claim to be the genius)

Only correction is most Ecoboosts use a 4cm turbine wheel, and I imagine the 3.5 is in the same category.
And while searching for that, I found these:
http://puregreencars.com/Green-Cars-News/Technology/continental-to-supply-turboc- - hargers-for-ford-ecoboost-engines.html
In order to prevent pressure from rising too steeply at high engine output, a waste-gate valve conducts the exhaust gases past the turbine. On the compressor side, a compressor bypass valve prevents air, which has already been compressed, from forcing its way back into the compressor housing when the throttle closes. This safeguard prevents compressor surge, which could damage the turbocharger.
This confirms the points I have maintained:
1)Waste-gates are to prevent over boost. They open as a pressure release when boost is above what is needed.
This is in normal use, NOT in racing only, as you maintained, due to your ignorant 'guessing'.
2) the throttle plate prevents charging the intake air when load is not required. The piping in-between compressor and throttle are frequently more pressurized than demanded.
3) Ecoboost regulates this post-compression using blowoff valves, or 'compressor bypass valves.'
Astonishing how the most incorrect person is the most convinced of his 'guesses.'

Wastegates control the amount of exhaust going to the turbine side of the turbo. A spring will keep the wastegate closed during idle or part throttle and boost will open it up regulating the amount of exhaust.
Another blow to the EGO boost you've been giving yourself with your fantasy-understanding of turbochargers.
Like already stated, the wastegate might stay closed a little longer at high altitudes to build the boost to the correct setpoint. Once the boost setpoint is achieved, the wastegate will start diverting some of the exhaust gas and the motor will operate the same way, regardless of altitude.
Wastegate is on the hot side of the turbo (turbine) and it works as a bypass valve as well, but is used to regulate boost, bypassing exhaust from the turbine once the preset boost pressure is reached.
The real purpose of a waste gate... how obvious to everyone but wwest.
And the grand finale:
EVERYONE knowledgeable about turbochargers know they are spinning 100% of the time, and waste gates vent excess boost.
This truck does do NOT 'torque out' in 'NA mode' before spooling the turbo. The turbo is always spooked to some degree , from .1% to 100% boost, depending on the fuel being burnt under idle to heavy load. Spinning the turbine is a natural effect of combustion.
You like aircraft? Turbocharged aircraft are on boost at all times while cruising at altitude. And the only time they can go to vacuum induction is at idle.
You. Know. Naught.
