Crossing fingers. Car in the shop for parts swapping..

[TopherSho]

Update:  Bad start switch thingy.    Ford is replacing the entire Button-to-control module for the PTS.  scary part... the assembly is in back order.  since June 2017 0_0 ?

so were stealing another dealerships parts.  also getting a quote to replace the turbo... Massive pain and cost incoming.

Well in for a penny in for a pound.  Just ordered 2550$ (labor included) 2 full turbo replacements. 

sigh... 

@AJP,  I think i'm going to ask you for a copy of my last tune (with meth) with TQ management for the 1-2 shift.  I wonder if i tore up my wastegate diaphragm with the hard 1-2 shifts and all that wheel hop and shuddering.

[SHOdded]

  You are going to retain the old turbos, right?  Give a good onceover and stuff to see what might have gone wrong with them?  Sorry it's hitting your pockets so hard ...

[FoMoCoSHO]

Do they know exactly what is wrong or are they hanging parts?

[AJP turbo]

I guess that's not terrible with new turbos and ford doing it...but I fear they are just changing parts even though my best guess is that the wastegate canisters are bad

And Topher I don't think vibration is the main culprit but maybe just the age ? But sure we can look into the tune

It's a educated guess on my part with AJP providing feedback.  It is not speed sensors,  its not the solenoid, its not the connectors, junctions hoses, misfire, knock sensors, or Tq source codes etc..

Couple that with the behavior I'm pretty convinced.  If not ... well I'm going to actually set it on fire because this dealership useless.. and there are no speed shops for 100+ miles that i think can do the job.

[SHOdded]

... and then it turns out it is the PCM connectors that have corrosion ...

[ZSHO]

I would say for $2550 can the dealer guarantee any repair with certainty that replacing the turbos will fix your issue! 
Agreed with AJP and playing guessing games by throwing parts @ it will add up to a substantial amount!  Dunno!  Z

ye-gods i know...  It is a risk but at this point all i have left is totaling it somehow.  Hoping the predictability of the of the boost problem is mechanical as it presents itself.

Just for funsies, have you checked your baro pid for accuracy?

That is built into the PCM and if you have a failing sensor or PCM I could see that causing all kinds of hard to diag boost shenanigans

probably not since I have never heard of it before now    ... how does it work?

It is your barometric pressure sensor and very important to speed density calcs.

Oh that's the 3bar/MAP.  I have three of them.  still has the same behavior.

No, I'm talking about the baro sensor that is mounted to the pcm board.

I double checked and there is a a 3 way correlation check between the sensors at startup and it looks like another 2 way @ 1500 rpm if I'm reading it correctly.

Pgs 137, 142

I'd want to make sure its not malfunctioning outside of those conditions.

Just curious, how much is it over boosting?
