Much has been said about being sure to return your truck to factory programming before taking the truck for warranty service. On the face of it that should be all that’s necessary to protect your warranty. That being said, I refer you to an excerpt from the 2006 6 liter manual: "Your vehicle’s Powertrain Control Systems can detect and store information about vehicle modifications that increase horsepower and toque output. This information cannot be erased and will stay in the system’s memory even if the modification is removed. The information can be retrieved by Ford Motor Company…and repair facilities when servicing your vehicle."
Simple question…is this true or just an effort to discourage the use of chips and tuners?
So if this IS TRUE how come it has not come up in this forun until now ?? 2006's have been for some time now, and i have tried a few different programmers,gms miser, etc. Now i am bummed out........as i am sure alot of 2006 owners will be !!
So if this IS TRUE how come it has not come up in this forun until now...
Not many people read their owners manual???
If true, I bet alot of people are going to get caught with their hand in the cookie jar. But just about everyone knows that tuners void Ford's warranty, but they do it anyway. Probably because they think Ford won't find out.
If Ford didn't have to pay for all the "tuner induced" warranty claims, lagitimate warranty issues wouldn't be haggled over.

It may or may not be reality. The truth of it is though, that the technology is there to do it if they want too. Anyone with a little knowledge of memory, logic, and cpu chips knows it can be done. The real factor in whether it is reality is what is the cost of the technology to do it. Mfr's watch all the costs of everything down to the penny, but eventually they will use the tech, if for nothing else but to keep warranty claims in check.
OK, so I posed the same question to some of the leading tuner manufacturers and here is one of the replies I received:
When returned to stock, our tuners put an exact copy of the binary image back into the truck, with not tell tale signs that there was a flasher.
Note, whenever anybody flashes a truck, or even disconnects a battery, the P1000 code will be stored in memory, this will be the only detectable indication that anything was done to the vehicle.
We often get Ford dealers to call us and ask how you can tell a performance flash was done to the vehicle, and our response is, with our software, there is no signs of modification.
It seems to me that either Ford is trying to mislead me or the tuner manufacturer is unaware of some hidden memory in the trucks computer.
Look. It is similiar to your home computer. Just because you delete a file from your hard drive, doesn't mean that someone can't recover that file who knows what they are doing. I have no doubt in my mind that the tuner companies do not know and understand completely the workings of Fords computer. As I stated earlier, the technology is there. It can be done. At this point, I assume that it is. This is why I will not change the programming on mine till it is out of warranty. Period. Mod other aspects of the engine, no problem. I will take my chances on those.

Neither. The tuner manufacturer is trying to sell you product, of course they're going to say either FMC can't see it was there and/or mention the congressional warranty act. The fact is people get their warranties voided every day...right, wrong or indifferent.
FWIW, I personally know that my coworker's son got his warranty voided after the truck went in to the shop, that was AFTER he removed the stuff before turning it in.
Even if you have a hook-up at a local shop that doesn't care about chips what happens when you're away from your local area and the truck craps out? You'll either have to pay on your own dime to tow it back to your shop or you'll have to risk it with some dealer you don't know. If you ask me, it's totally not worth the risk.
i was told to return a pcm because they wanted to recover some snapshot information. Just the pcm, no battery, nothing else. Take that for whatever you may think.
I completely agree. No chips or tuners for me. I have worked with computers and electronics for years and have no trouble believing that FMC has some sort of non-volatile RAM that is capable of recording engine parameters in a way that can't be erased or even accessed from without special equipment (the "snap shot" previously referred to).
From what I have read here and elsewhere, I must conclude that Ford does have a way, at least in the '06s, to tell if, and perhaps even when, horsepower has been increased beyond factory specs and that this "feature" has not yet come to the attention of the chip/tuner manufacturers. Given that, flashing an '06 would seem a very dangerous thing to do indeed!
I too have been up and down about getting a tuner... but now, well its out the door.. if gas prices dont force me to trade the truck in... then i don't want to void my warranty just becuase someong "the turner companies" dont know what there talking about... so for now ill wait until my 3/36 is up and then worry about it... besides by then i should be on my way out to the gulf again or on my way back... so ill have to money to do it all right the first time....
This is a topic that seems will never die. The tuner advocates say that you can't tell, and we as Ford techs say we can tell. So you have to decide if it's worth it or not.
As an example. If you disconnect your batteries indefinitely, your PCM still remembers your total mileage. Don't doubt there are other values they can store as well.
