I appreciate the help.

The manifold looks pretty easy to remove. I ordered new gaskets, end brushes, picks and an extension for the drill.
I haven't found any torque specs on the bolts, I'll keep looking.
I also don't know if the coolant crossover tube is attached to the manifold. I'll get som mirrors or the scope out to check.

Thanks SHOdded. look at them when you have the time.

i haven't had time to look at the logs yet, today or tomorrow most likely.

yeah tuning devices are a different beast from obd scanners.

i have to look up the intake removal info. but usually the best cleaning is done with walnut shell blasting, something to leave to the pros. may require each cylinder to be TDC before attempting the valves on that cylinder so there's that effort and time involved. if that is true, you cannot address all cylinders simultaneously, you have to go 1 by 1.

I did a log with fuel pump percentage, duty cycle and module duty cycle.

I still see the TB opening to ~30%, closing and then opening up to ~80% slowly.
Looks like this is during the shift to second.

This live link is pretty nice, I need to understand what more of the PID's actually are.

I was thinking of pulling the upper intake and cleaning the valves, but I can't find much info as to torque specs for the bolt, sequence and i assume the bolts are too small to be torque to yield.

Thanks SHOdded.

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.

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.

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.

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.

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.

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.

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.
