Too much boost and engine load.

Boosted150 · November 05, 2016, 06:19:59 PM

Hello guys just had this weird thing happened, just accelerating maybe 30 - 40% throttle felt truck start shuddering glanced at Gauges and boost pegging 20 psi with 2.2 eng load I instantly let off. Will be running a data log in a few hours once I get out of work but this is bothering me I've never seen over 18 psi or 2.1 load especially part throttle. Truck has been on the same 91 custom tune for 12k miles. Any idea what would cause this? Picture of Livewire min max readings.

Check your vacuum lines here... Mine does that when it pops off the hot pipe there.

StealBlueSho · November 05, 2016, 06:35:32 PM

Do you monitor wastegate duty cycle? I noticed when mine did that the WGDC dropped to 0 to slow the turbos downs as much as possible.

Boosted150 · November 05, 2016, 06:46:45 PM

Didn't see any vacuum lines off and do not have wastegate percent up. I will check when I log it tonight though.

X2 on what SBS said.

Ok just did a quick data log and something is defiantly going on I'm about to put truck back to stock for safety reasons. Help me on this guys as I'm still learning gas side of tuning but here is my quick wot run. I got out of it since I saw knock, rear fuel pressure drop and AFR hitting .5.
I don't know how wastegate percent looks but I'm all open to learning.

I just went through all the vacuum lines they were all tight and connected.

When did you last clean the MAP sensors, and have you verified there is no buildup in the intercooler? The intercooler is still stock, no holes drilled?

I have not cleaned map sensors is this a normal on ecos just hit 30k miles?. Yes stock intercooler no holes I'm planning on upgrading this winter and save stock one, I can pull off charge pipes to check though. I also just changed the oil and noticed a strong gas odor and sending a sample into blackstone.

Yup it's normal, especially on tuned EBs. Use MAF cleaner/electrical parts cleaner. Easy peasy. Spark plugs are pretty commonly changed by 30K also. Fuel dilution is a common problem on DI engines, and your F150's PCV system may be suffering from excessive blowby. Pulling plugs will tell you if too much fuel is entering the chamber. A compression test will tell you how the piston rings are doing.

How many miles since your last oil change?

StealBlueSho · November 05, 2016, 11:16:43 PM

Yea... Still seems to me the car loses its vacuum signal from the turbo somewhere...

Boosted150 · November 05, 2016, 11:33:29 PM

Yea I did NGK 6510 1 step cooler gapped to .030 at 20k miles I have 28,500 miles on truck. I change the oil every 3-4k miles and it was changed 3 days ago (pennzoil platinum 5w-30). I will have to wait till tomorrow to pull plugs and triple check vacuum lines my garage has my other project in it right now.

You've done everything right, hopefully it is something simple as a sensor or a loose wire. Maybe even a calibration update like they did for the intercooler.

OVERFULL

FORD:
2011-2014 F-150

This article supersedes TSB 14-0040 to update the Service Procedure and Part List.

ISSUE
Some 2011-2014 F-150 vehicles equipped with a 3.5L Gasoline Turbocharged Direct Injection (GTDI) engine may exhibit a raw fuel odor from the engine oil and/or an engine oil level indication overfull.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

1. Determine the part level of the positive crankcase ventilation (PCV) valve by its color. Refer to Workshop Manual (WSM), Section 303-08.

a. If the PCV valve color is black proceed to Step 2.

b. If the PCV valve color is brown proceed to Step 3.

2. Replace the PCV valve. Refer to WSM, Section 303-08.

3. Change the engine oil and filter.

4. Determine the vehicle build date. Refer to WSM, Section 100-01.

a. If the vehicle was built on or before 10/24/2011 proceed to Step 5.

b. If the vehicle was built after 10/24/2011 proceed to Step 9.

5. Remove and discard the brake booster vacuum hose. (Figure 1)

6. Install a new brake booster vacuum hose. (Figure 2)

7. Install a cap over the open port on the air cleaner outlet pipe. (Figure 2)

8. Reprogram the anti-lock brake system (ABS) module to the latest calibration using IDS release 93.02 and higher. Make sure you are connected to the internet when entering module programming to obtain the latest updates. Calibration files may also be obtained at the website.

9. Reprogram the powertrain control module (PCM) to the latest calibration using IDS release 93.02 and higher. Make sure you are connected to the internet when entering module programming to obtain the latest updates. Calibration files may also be obtained at the website.

NOTE : 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.

Thanks what do you think of fuel pressure dropping off and afr dropping to .55 I've never seen that?

Thanks that definitely sounds like a common issue. I'll see what a UA analyst says then I might have to take it in for that problem.
