Quick question?

Doesn't a Tune on a new Stang void the warranty? :bang:

 

Hi,
Just flash back to stock when taking it in....no problem

 

I heard that Ford can tell when it's changed. I know they can on my SVT Focus when getting a custom tune and reverting back. Anyone know if the Mustang works the same way?

 

The ford dealers around seattle say they will honor the warranty as long you havent put a supercharger on the car, installed nitro system or touched the cats.
Basic bolt ons such as CAI , axle back exhausts , and a tune wont void the warranty out this way.

 

I don't understand how they can void your warranty for touching the cats. I thought they would just not fix your exhaust if something happened to it. Otherwise, how does changing the cats or removing have anything to do with messing up the engine? Am I missing something here?

 

I asked the question when I bought the car. I asked about headers, cat-back, X-pipe, etc. The service manager said as long as I didn't do anything to the cats, I was okay, but if they were touched, then all bets were off for entire exhaust system, modified or not.

Also, I asked about other parts. I was told by the same people that simple bolt-on parts and a reflashed tune would not void it, but anything more "serious" and they'd void it for sure.

Pretty much the same story at four different dealers.

 

Interesting - I always thought that they would try to void the warranty for a tune. That is what some other people said in the past. And it sounds like if you have already done your headers and catback, then it wouldn't really matter if they voided your exhaust parts. B/c they would do anything with your parts that are already aftermarket. Am I correct with this thinking?

 

I only did the catback today. I haven't touched the midpipe or headers (yet). On this car, if you replace the midpipe, your'e replacing (or leaving off) the cats since they are welded to it. You'd have to cut them off and then attach some sort of pipe to them to keep the factory cats. I know, doesn't make much sense. Maybe I was looking at them wrong when I was putting in the exhaust today, but that's how it appeared to me. But I am no expert. Any of the legions of people who are more expert than me, please chime in (if you're up at this hour, that is!).

 

When I brought my Gt into Ford to activate the window feature of the anti-theft system, I was talking to the computer tech doing the job and he said he would be able to tell if the car had been reflashed with a tune and then put back to stock tune. He also said with new models Ford looks at almost everything on warranty claims and a reflash has really yet to be determined one way or another. However, If you retune and blow a motor or burn a piston you can count on kissing your warranty goodbye, but if the mod does not cause the problem they will honor your warranty. This info is from a Ford service tech and not someone in management so make your own calls on this topic.

 

First = I really have no actual knowledge of where Ford stands with voiding warranties on mods, etc. I know there is a law on the books which in some way protects the consumer as long as the mod(s) do not cuasue the problem. I think the trouble comes in that great big grey area on what is suppose to be and what a specific dealer will say. - leaving the owen to fight it out with Ford and/or in court.

 

From what I have read here and on other forums once you flash the factory tune in it disconnect the battery for about fifteen minutes and it erases all traces. If this turnes out to be incorrect I have been had for sure.

 

Let's say that all traces of the tune can be removed prior to taking the car in for service. What about the added components, i.e. an intake, that require the tune to perform properly?

It seems that just about everyone will at least have a CEL warning if not engine performance issues with an aftermarket intake and stock computer parameters.

I would think that service personnel/dealers would question this.

 

Better safe than sorry IMO, save those stock parts, you may need them...
