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

BTW, transmission adaptives IME do not change with a KAM reset, that is just the PCM portion.  The TCM / SBA portion has to be reset with IDS or similar highend scan device.

I’m not 100% sure of that? Correct me if I am wrong but LMS has always preached that after an initial flash the transmission shifts can be harsh until the adaptives kick in. I would think that the SCT platform is similar.

The tuner may reset the TCM adaptive tables, IDK.  You would have to ask them that.  But these tables are independent of the tables in the PCM.

Agreed with SHOdded! THe Trans adaptives can only be reset with IDS or similar high end scan tools!  Z

! No longer available
 
Added 1/3 to 1/2 a qt of tranny fluid and retested.  Still stuttering hard, making it into 4th was questionable.  I have a brad-cfg log of the event,  not a new tranny log for it so i will upload it later.

I set up a tranny log that has all the tranny pids EXCEPT voltage so i could keep rpm and some of the other normal stuff.  i will try to get a log of the issue using that tonight!
 
Here is the brad-CFG log of today's run.  Note how long it takes @ WoT to get to 4th gear,  the choppy rpm,  choppy intake timing.  look at the back half of 3rd.  note the waste-gate gets choppy as well and the whole last 3-4 seconds is super jittery awfulness.  yet.. no tell tale source of issues.

I cannot make a tranny log tonight.  it will have to be tomorrow. :( 

After the tranny log i will follow the Adaptive reset procedure. but i will note that i have had the cables off before for overnight work and not had to do this.  on the good side.. the wife BEGRUDGINGLY singed off on 500-600$ more for a possible TQ-converter. 

But i think that's it.  after that shes done spending money and i sadly think she will be right.



 
Checking voltage and resistance values on the TCM/SBA will help eliminate that as a physical concern.  Very DIY, will only take your time, and a DVOM.  Same thing with the transmission range sensor.  If the connectors on the PCM have not been inspected, they can be inspected, cleaned and greased as a DIY project.

Let's see what the trans log shows, if anything.

I can see in the log EVErYTHING gets choppy halfway through 3rd gear.... wastegate, rpms, manifold pressure, and speedo.. not sure what would be causing EVERYTHING to get choppy like that...
 
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?
 
Only reason I ask, is if the issue persists while stock, instead of dumping money into guessing, it might be worth while paying a decent dealership hook it up to their IDS system to see if they can find anything. It would be cheaper at this point than throwing parts at it and praying it works.

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.
 
 
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!
 
VIN: 1FAHP2KT6AG107151

Strategy: DMJKBLA

ECU SWPN: AU7A-14C204-GTC

For comparison considering we have the same strategy...

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.
