I have had my Ecoboost since Saturday, less than a week, and I have a question. When pulling away from a dead stop there seems to be a lag in throttle response and almost feels like the rear wheels skip a bit. Is that just the way its supposed to be?

 

There is a re-flash of the computer available for trucks built prior to 2/7/12. I don't know, but that might help the problem.

 

Eddie, do you have any more information about that? Is there a TSB?

 

Have you noticed it as well?

 

Turbos will typically have a lag depending on how quick you are on the throttle.

 

I don't notice any skip feeling with my 2012 Ecoboost...the only real lag I get is if the transmission is downshifting.

 

My 2011 doesn't have any noticeable turbo lag, unless you really hit the gas hard and even then it's minimal.

 

Well, no, I don't think I have noticed exactly what you are describing, but I am not sure with many things here.
You know, this is the first vehicle I own with an automatic transmission, and I am still in the process of getting used to it. Everything kind of seems to have a delayed response when comparing to a stick shift, LOL.
I was just wondering about this TSB, it's always good to have the information.

 

I am wondering of what I;m feeling is just the nature of the transmission. I'm REALLY easy on the throttle in town to the point I might be too easy. Letting off the brake and enough throttle to get moving.

I noticed almost the exact thing in my wife's new Highlander. So it may be how I am driving in town

 

Here is the text of the TSB borrowed from another forum.

12-2-10 3.5L GTDI CALIBRATION UPDATE - VARIOUS ISSUES - BUILT ON OR BEFORE 2/7/2012

Publication Date: February 15, 2012

FORD: 2011-2012 F-150


ISSUE:
Some 2011-2012 F150 vehicles built on or before 2/7/2012 and equipped with a 3.5L gasoline turbocharged direct injection (GTDI) engine may exhibit a malfunction indicator lamp (MIL) with various diagnostic trouble codes (DTC) and driveability concerns.

ACTION:
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

The calibration update contains improvement actions and enhancements to address the following conditions:

Intermittent engine surge during moderate to light loads at cruise.
Enhancements to misfire monitor detection.
Powertrain control module (PCM) DTC P0430 and/or P0096.
NOTE: INSURE ALL HARD FAULT POWERTRAIN DTCS ARE ADDRESSED PRIOR TO PERFORMING THE CALIBRATION UPDATE.



If the vehicle exhibits DTC P0430 replace the left bank catalytic converter. Refer to WSM section 309-00. Proceed to Step 2.
Reprogram the PCM to the latest calibration using IDS release 77A.03A or higher. This new calibration is not included in the 2012.1A DVD. Calibration files may also be obtained at Buy Motorcraft Parts Online | Official Motorcraft Auto Parts Site | FordParts.com.
NOTE: PLEASE ADVISE THE CUSTOMER THAT THIS VEHICLE IS EQUIPPED WITH AN ADAPTIVE TRANSMISSION SHIFT STRATEGY WHICH ALLOWS THE VEHICLE'S COMPUTER TO LEARN THE TRANSMISSION'S UNIQUE PARAMETERS AND IMPROVE SHIFT QUALITY. WHEN THE ADAPTIVE STRATEGY IS RESET, THE COMPUTER WILL BEGIN A RE-LEARNING PROCESS. THIS RE-LEARNING PROCESS MAY RESULT IN FIRMER THAN NORMAL UPSHIFTS AND DOWNSHIFTS FOR SEVERAL DAYS.

OK, I think it might be the traction control. I turned it off tonight and there is a difference. I don't think it knows what to do on our rough multi surface streets here in town.

 

Hey, thanks cgartly for posting that.
Now I am wondering if it would be worth it to have that TSB done even if I don't really experience any symptoms? What are others who own the EB do? Yes/No?

 

Check the build date on your truck, if it's after 2/7, you already have the TSB incorporated from the factory. Another thing to consider is the "drive by wire". There is a very slight throttle response delay on the drive by wire trucks. It's not a lot, but I have noticed a difference between my '11 and my 'ol '97 that had a cable.

 

There's also a built in lag in the drive by wire system. In my mustang the 1st thing I do getting in the car is turn off the traction control. I can't recommend this for everyone

 

That is what I have been doing. Makes a difference
