I had permission from the dealership to install the other tune now like 75,000 miles later this is what happen. I took it in to ford and said it might be my alternator and they said , computer isn't keeping memory and charged me 99 dollars to look at it. $hit and I still don't have it fixed. They said they don't cover the ecm since I changed the parameters of the tune to adjust to the cold air kit.

Gosh Guy I hate to bring bad news but that is an alternator problem. I know mine was replaced fortunate for me it was cover on my extended warranty.

I am currently having the same issue with my car. I pulled error codes P0340 & P0344.
I plan on leaving my UD Pullies and K&N CIA on the car, but flashing SCT back to stock.
Did the dealership fix the issue?
Does Ford honor TSBs even if the warrenty is gone? I have 54k on my car.

It's the alternator with these codes. I even changed the cam position sensor,both of them before I changed my alternator. I started getting the codes, then my car starting dying if I didn't drive it everyday. Fixed the Alt. and it all went away.

I am not putting any modding down,heck I plan to do it but I am going to ask my dealer first and find out if it will or not,if it needs to be installed by them fine I will pay the xtra cash,if they say no I will wait till the warrenty runs out,part of the cost of the car is the warrenty,it's your money do what you want to do.
Most dealers don't mind a few minor mods as they realize that your aftermarket exhaust did not cause your alternator to fail. They won't say "hmmm aftermarket mods...no warranty" because they can't. They need to prove that the aftermarket part caused the failure before they can void the warranty, and they can't void your ENTIRE warranty even it if did cause a failure. They just can't warranty the part that the aftermarket part caused to fail.
I think that some people are just a little paranoid about mods....

Does "You screwed yourself out of a warrenty fix" mean anything,I seen a few post that people have said Ford will know you flashed or changed stuff in your computer no matter what you do,be a bummer if something major and they won't cover it becuse of a few minor mods,you may have just voided any engine warrenty you have now.
Hope not.

Ford has no way of knowing the flash history
of the PCM unless they do it and document it.
The few that say so are dead wrong.
Period.
He did not screw himself.
His warranty is as good as the day it was sold new.

Wow, I started this thread 4 years ago...
Anyway, The Dealer did give me a hard time about the Mods and said they would charge me for diagnostic time if I left the Mods on the car, If I removed them then they could properly diagnose the issue, So I did.. They did replace the Alternator but that did not fix it, it turned out to be a bad phaser Gear and the dealer covered it under warranty.
Thanks.
