I haven't driven the car in a few days, but this morning when I did I received several warnings:
AWD OFF
Service AdvanceTrac
Lane Keeping Sys Malfunctioning...
And the kicker was that at one point the warning about LOW engine oil pressure
where do I being with my troubleshooting? I've simply turned the car on/ off several times throughout the day. I plan to tune back to stock and change back to the 2 bar MAP.
Battery original ? Low battery voltage tends to make the car act wonky @ times!
Check to see if any codes are set! Z
x2. Sounds like a good setup for a misbehaving battery.
It's not the original, I replaced the battery about 6 months ago. But I'll look to get it tested

Also, did you have an obd adapter plugged in while the car was off? Battery Management System reset with new battery?

yes... still do

no, I'll need to look into this
A) wonky behavior has known to happen with obd adapters on startup
B) the pcm will not charge the new battery properly without a BMS reset, thinking it is still the old dying battery

What OBD adapter do you have plugged in? I've seen these same messages (minus the low engine oil pressure) on my previous 2011 that I had tracked down to a flaky OBD dongle plugged in. It was causing those systems to reset. Try running without the adapter for a bit?
Your describing the exact series of warnings I get when my tune fails to load on my p.o.s sct itsx.. lights flash once and it dings at you and throws all same warnings. IDK of its related but maybe a dying battery caused pcm to do something weird with tune? Revert to stock and reload tune and see if issue persists before removing parts?

It was simply the OBD II adapter. After well over a year of leaving it plugged in, it was the cause of this issue. Pulling it out prior to startup allowed for a normal behavior. I was able to reinsert the adapter and get back to torque.
I am still going to look into how to reset the Battery Management System.
Thanks for the help, I feel like a dunce creating a thread that was caused by something so simple.

I wouldn't worry about it...It's good for people to see since many people wouldn't think that could be a problem...Someone will see this thread and it may help them

Nothing is ever simple with cars nowadays, LOL. Good to periodically remind folks of possible solutions to such issues.

As we have been down this road Before,
and it cost me a ECU, a tow, An SCT lockup (back to SCT), ETC ETC.
WORDS OF WISDOM: and this ALSO comes from a Ford Master Tech:
Never load a Tune Without Having the Battery on a Dedicated Charger,
and that means having the Battery at Full Voltage. Make Sure the lights
are Off, Battery up to Snuff, and you will be Fine, Low battery Voltage, You
run the risk of the the above, (it DID) and >:( it can cost you a bundle...
A good warning to heed.
Some models and or poorly designed / broken models of OBD2 adapters have caused the same or similar issues with Nissan Jukes and I am sure other cars.
Here's the most recent member who Fried the OBD PORT while leaving the adapter plugged in! Z
Beware all ecoboost owners!!!!!!!!

FYI I have the OBD MX Bluetooth. I also do not leave it plugged in anymore :)
Seems no adapter is immune.

Do you think it's appropriate to say that the mx adapter may have fried the obd port? I remember that persons flex having a whole lot of unresolved problems and I can help feel that he had a lemon or flooded car or something else wrong
It was one problem after another ...im just not sure it was an OBd adapter that is simply broadcasting the signals coming from the port that can "fry " things
I thought the mx adapter was the more expensive non clone device that is recommended for module programming with forscan and the better option because of better protocols or something?

I guess its better to Preach Precaution and anything is possible!
I would hate for it to happen to anyone on here that's all! Z
The MX adapter is indeed of the highest quality. The frequency of issues are significantly greater with the "cheaper" ELM327 devices. The main issue is usually to NOT have the device plugged in while starting up the car. After the car is started, it should be ok to plug in the adapter. OR if the adapter can be fully depowered when the car is shutoff, some of them like the Veepeak have an ON/OFF switch, that is another option. Probably some interaction with the multitude of systems checks the PCM does, and the tool trying to retrieve data likely interferes with that. Not to mention plain ole EMI.
I don't think it harms the OBD port, unless the adapter is really of poor quality to begin with. $5 adapters in $50,000 cars ... no thanks.
