my 2017 SHO w/PP

[SHOdded]

not sure where the oil is coming from unless it is from the oil filter, engine oil pressure switch, etc. if  you don't see any oil elsewhere, i would clean it off and keep an eye. possibly ptu venting but the oil would have "that smell", an axle seal leak, or the front main cover (timing cover) leak.

as for turbo videos, ones specific to the ecoboost turbos of your style should be the pertinent ones. these are smaller turbos than normal to allow faster spoolup i imagine less room for "slop" as well. but idk.

not sure where the screens are on the oil feeds, but i would hope at the end closest to the turbo to provide max filtering. will have to see if i can find this info.

[Cobra93]

I'm not sure either. Ill watch it and try to check the bolts holding the halves together.
The only place that i could see a possible leak would be the break between the compressor/turbine side where the 4 or 5 bolts keep the center section together.
I doubt the turbo was built incorrectly.
This is a link to the video I was referring to.
Those/his truck turbosseem to be water cooled. Mine look like there is a plug

This fordtechmakuloco shows the screens you linked me to starting at 3:45 sec if the video doesn't start there.

I don't know if the truck version or year or what is different, but I only have 1 solenoid (cam phaser?) n each bank. Most of the videos seem to have 2 per bank?

Thanks, SHOdded.  I may not have much of anything until this weekend.

[SHOdded]

yes the f150 and sho engines are different variants. the sho engine is based on the transverse 3.5 cyclone engine and retains the vct configuration. the f150 is a longitudinal ti-vct engine thus the 2 solenoids per bank. the sho engine was never updated in this regard.

[Cobra93]

I have the pcv valve, vacuum pump and the gaskets
I replaced the pcv valve (numbers match), I think the old one is okay, but...

I checked the canister purge valve. It holds 30 psi for more than a minute.
Any more and the connection blows apart.

The throttle body and rear turbo are completely dry, I will continue to keep an eye on the rear turbo.

I found a video "legit street cars". He bought an sho at auction and is doing a Gearhead tune/intercooler and a PPE exhaust. He checks his turbo and states a small amount of movement is okay. I don't know for sure, but he seems knowledgeable.
Start at 14:34 if the video doesn't.

I may not check the rear turbo as the video looks worse than the small amount of play I have in my 97,000 mi front turbo.

So far things look pretty good to me.
I'm a bit afraid of what I'll see if I put the bore scope down the map sensor hole to look at the intake valves. I'm not sure if it'll fit.

If the timing advance is correct (~19° @ WOT, Ive only put 93 octane in the car), I'm getting 10 psi of pressure from the turbos, the hpfp is @ 2,400 psi and I have no misfires (plugs/coils/injectors are okay) I'm not sure why the car is so slow.
I also still have the random time I see boost the first time I go WOT.
The times I got from torque were with a full tank of gas.

I'm still working on the engine mount.

What else should I check next?
Thanks, SHOdded.

[SHOdded]

everything looks good except maybe for fuel pressure, assuming max is truly commanded. at this point it seems like an intermittent problem since it is only on the first pull.

i believe in 2013 the max hpfp pressure was raised to 3000 psi. 2400 is correct for 2010-2012 MYs.

would log both fuel pump duty cycle as well as fuel pressures from idle to wot to idle. see if you spot a difference between pull 1 and any run thereafter.

could be as simple as a fuel pump control module, or not.

[Cobra93]

I sort of figured out how to log in torque.
I have 2 idle to ~beyond 70 mph runs on here.
I hope this shows up okay.

I added custom scripts, then imported .csv file to torque from ecoboostsho from this forum back in '14.

When I connected torque to my car "fast connection was disabled".
I've not had that happen before. Data corruption, fast communication disabled, OBD device may be faulty.

I'll keep researching how to log so I can post some information that is actually helpful.

Both runs had 0-2 psi of boost until the top of first gear, hence the 7.1/ 6.9 0-60 times.


Thanks,  Joe.

[SHOdded]

it is possible the pcm is throttling boost until it is satisfied the vehicle will respond. i do not recall what the max oem fuel pressure is (untuned), i will see if i have member logs to verify. curious that there are no fuel pump duty cycle datapoints tho, maybe wrong PID. seems like generic pids for that and knock sensor count? torque pro provides every 100ms resolution capability iirc. what adapter are you using. i highly recommend the obdlink mx+ not a "generic" for these purposes. a tuning device affords 10ms resolution.

one of the reasons that the pcm will throttle is due to torque management kicking in, but since you have not mentioned any wheel slip or tire buckling type feeling, probably not the case.

the system is awd, but it still should not throttle that long. it should switch to fwd mode if the rdu is malfunctioning, and of course it will impact 0-60 times, just not sure how much.

[SHOdded]

unfortunately i do not seem to have torque datalogs, so i have attached a datalog from an sct x4 i believe. you can clearly see the pids they are using, need to find similar vehicle specific, not ford generic, pids in torque.

fuel pressures are in MPa, approx 14.5 psi conversion.

[Cobra93]

Correct, there is no power or wheel slip.

My obd2 adapter warns of data corruption.
I ordered another, it needs an app to work.
I have another one arriving today and should be able to log something that will actually be useful, I hope.

Iwill try to use the x4 to get a log. I will have to search how to post it. I'm referring to the one Matt sent.
I'll look at the log you posted, thanks.

Thanks. I hope to have some info tomorrow after work.

The other odd thing I have noticed is that half throttle seems strong, lots of torque, but WOT seems like less power. Sounds weird, but that is the case at times.

[SHOdded]

one other possibility if the vehicle has been tuned in the past is that it is still running a tune, and/or the pcm is bricked. since the vehicle is still driveable, i am leaning to a bad tune rather than hardware issues.

let's see what the x4 reveals.

[Cobra93]

Not sure what's going on with torque. I ordered the obd link lx.
It connected fine, but the same error. Data corruption, fast transfer disabled, adapter may be faulty. The obd symbol is red in torque as well as my phone symbol. The GPS and car are both blue.

I hooked up the x4 this morning and recorded until after I hit the way.

I assume (new to this) x4 records whatever I choose as the configuration. I assume in live wire on the pc if I choose the file Matt sent to log, it will show only that data.  ??

I have to figure out how to save the file and post it so you can view it.
The car didn't seem to have the sudden no boost/boost issue this morning. It wasn't amazing, but seemed to be the normal acceleration I'm used to.

Something else I did notice.
I sent my strategy code to Matt, but the file he sent back to me seemed to have a different code. The first 4 may have been the same, but not all.
I wasn't in a hurry as the car isn't sorted yet. I'll look again after work.

Thanks, SHOdded.

[SHOdded]

well its been a while since i ran a tune, so i am not sure but it makes sense the strategy code would change.

that data corruption on the obd port is an odd duck, but if it is possible, i would disable all other bt connections and try again. many times we have had owners have all kinds of dash lights lighting up on startup when an adapter is already plugged in. i think 2013+ have more issues with this than 2010-12.

so plug it in after you have started the vehicle and see if that makes a difference.

[Cobra93]

I tried to get the obd to work, but keep getting the same error.
If I go into settings (in torque) I do see communication with ecu is the error.

I also found a post by stealbluesho on how to load a config file on the x4 to use that config file.
I do have a file, but I believe it it a generic ecoboost file.
I dropped it into the box to attach it, I hope that's correct.

There are 2 WOT runs on this file. The car seemed decent during both.
One thing I do see, but maybe it is not what I think it is.
kPa manifold absolute pressure is  26.4 max. That converts to~3.48 psi. ??
Is that the actual boost? Torque shows ~10.0 psi.
I assume I'm wrong on my assumption.

I did get Gearheads config transferred to the x4.
I just checked the config is there and selected.
I will try to copy what he has selected and add fuel pump duty cycle to it.
I hope you can see the log with live link.

Thanks SHOdded, I'll have another log tomorrow with geaheads config.

[Cobra93]

I did 2 wot runs this morning with matts config file.
I did capture the "late" boost issue.

I'm not sure what I'm looking at. I can only go off what I believe
I understand should be happening.

I don't know why the throttle angle  initially hits 30%, then slowly tops out at 77% at what I assume is the shift into second gear.

Fuel rear pressure, rpm, boost, load, MAP kPa, throttle angle actual all seem to be on the same "slow ramp up" curve.

I know enough that the car is going to protect itself and can do it very quickly.
I don't know what a normal log like this should look like.

I believe that lack of boost could be an issue somewhere else, like fuel pressure being low, not necessarily a problem with the actual turbo, piping and so on.

I hope you can see the log and something is obvious to you.
Thanks, SHOdded.

P.S. I'm working on picking what to log in addition to matts config, adding fuel pump duty cycle as you suggested.

I did try what you suggested about waiting to plug in the obd adapter, same issue.
It would seem this issue started when I loaded the .csv file and selected items to log. I will try to remove that and see if it works like it used to.
I still get realtime data without issue. I don't know.

[Cobra93]

I did a factory reset on torque and removed all the what to log PIDs.
Torque connects with no errors, the 4 symbols (GPS, phone, obd adapter and car) are blue.
Fast transfer is working.

It must have been the .cvs file I loaded from the forum (ecoboostsho had posted). That was from '14 or the couple of PIDs I entered manually.
Not sure. I may try to find more pids and enter them manually or try the file without the ones I entered manually.

So everything is working as far as torque is concerned.

This was a mostly normal log from later in the day, looks similar to me.
