please help me understand what the crap is going on? (wastegates) : Resolved!!!

[TopherSho]

yeah... that is he problem now.  This isn't a TQ converter.  .. this is some kind of 'noise',  bad harness, bad ground, pcm.

Were super close to either being fixed.  Or reverting to stock and selling it.   I am not chasing wiring harness demons.  I just don't have the skill.

I am still going to log the tranny .. but i am mentally prepping that we wont find the TQ converter is bad.  once we see that I will drop in the fresh hand made tune from brad (from scratch new tune on both updated SCT's) and at the same time do the needfull PCM reset for adaptives.

After that all I can do will be to get a PCM on the web,  and try to have ford install it.   That will be the last of the car money, no more water in the well.

Is it still having the same problems when stock?

I do not think I drove it long enough on the stock tune.  The 15-pound tune went 'bad' like 24-36 hours later after multiple restarts.    the OEM tune was on there long enough to get the OAR to .96,  and get a clean set of logs.  Then it was off to the 14 pound tune,  where i drove it for a few hours to get the OAR set and log it again.

I may not have driven the OEM tune enough,  and even if it repros,  the DAMN dealers did not want to touch it, and were unable to provide any assistance.

Agreed with SBS! FWIW you can always find a used PCM on Ebay for fairly cheap which is the (Brain) of the vehicle and just have it programmed @ the Dealer if that's the case!!!
What's your VIN Number?  I'm presume it's an earlier build Job 1 ?

Brad also suggested a PCM swap ..

[TopherSho]

VIN =  1fahp2kt3ag106362

STRATEGY =  DMJKBLA

ECU SWPN =  AA5A-14C204-DF

[TopherSho]

ok this is weird.. Why does my SWPN not match up to any known ford ecus ?

ECU SWPN =  AA5A-14C204-DF

Does not show direct replacment by either of these ::

Do i have some early one-off s*** jugging weird version of an ECU ?

edit .. man i am in a bad mood.

Topher,
Weather been sporadic up here.  If you can start tracking weather or at least keep it in the back of your mind when these events are worse/better.  Not sure if car is garage etc..

My last car (Caddy STSV) suddenly started throwing ABS/Traction control failure messages in the rain when leaving stop signs and turning.  ONLY when raining.  I did a harness check and connectors and all was good, so has to be some other failure that only cropped up drivining rain..  Weather can be a beast up here on electrical type issues, just another thing to keep in back of mind.

And yes I sold that car within 2 months of it starting to do that an bought the SHO...  LOVED that car, but too many gremlins in 2yrs of ownership and that was last straw...  I feel your pain!

Yeah i saw those a long time ago when i car-faxed it,  and did another site lookup.  nothing jumps out at me.

I was going to head down this same path. If you're still in Oregon, the moisture content of this year and all others combined could be your problem. Especially if the car is parked outside all the time. If you had any problems with the original battery leaking down on the harness below, over time would create a problem.

Mine leaked and acid got to the harness but I cleaned and wrapped existing wires to prevent any possible electrical problems. I was close to the coast too so it was worse. You may have moisture though or rust problems somewhere because of the constant moisture you're surrounded by.

There were a few TSB related to the PCM that kind of popped out @ me! Dunno!  Z

I saw that ... but kind of ingore it.. the symtpon doesnt see 'right'.  Do you think the are referring to the ACC brake feature?  i'm not sure that would create the jitter... but disabling the ACC should kill that for a test ?

Aslo ... my ECU part number.  it doesn't seem compatible with the any of the replacement units i have found.  Thoughts ?

its possible.

[StealBlueSho]

I will tell you this... and I have mentioned it before.... to date, I have not had an SCT based tune regardless of tuner that runs 100% all the time. Torrie flat out couldn't get my fuel pressure under control among other things... BCB damn near blew up my motor with their 2nd revision(going 1.14 lambda in the middle of a boost spike will do that) and then told me that I don't have enough tables for them to work with.... and Brad has spent HOURS working my tunes over to come up with a tune that flat out runs 99% of the time. I still get a stutter in the upper RPMs once in a blue moon....

A lot of those TSB are resolved with a strategy update which you have the latest... so I dunno dude....

I am not sure it's mechanical since it runs fine after a flash....

I would @ least try to remove the PCM to check for lose or corroded connector's or (water intrusion) to validate address your concern!
FWIW would try to rule out a malfunctioning Fuel system!

BTW How's the oil level? Sorry if this was asked before!  Z
