I'm not condoning or promoting tunes here, so please don't make a flame war out of this thread. What you do you with your car is your own business, and there are reputable tuners out there that will back up their work like Livernois. I just wanted to spread the word about what people are getting into when modding their new cars in case they are unclear about how it works.

This is why I won't be tuning my Powerstroke until it surpasses its 100K powertrain warranty (only 25K more miles and counting :dribble:).

Yeah, it's got us Mustang guys all up in arms. I understand why they did it, but it still ****** me off that they're going so hard-ball on an issue that is at least partially attributable to poor engine design.

Cylinder #8 ******** the bed pretty regularly. Yes they all have tunes, but if the tunes were really at fault, you'd think some cylinder other than #8 would occasionally blow. Actually, there is one known case of a stock engine blowing #8.

Most mustang owners are about as sharp as a bowling ball. :laugh_ti:

Says somebody on a forum dedicated to cheap, slow tauruses?

What does that have to do with being bright?



Im not the one that expects a MFG to cover failures to modified rigs.

That not-so-bright individual would be you.


Do you HONESTLY expect a MFG to warranty failures with modified rings? Should I simply come out and call you a ********?

Thanks for posting, Typhoon -- it's about what I expected and I believe what most here expected too.

"Dumb *****" put words into others' mouths. I at no time said I expect Ford to cover warranties caused by tunes. What I'm saying is that I'm not entirely certain that the tune is the only cause of failure of cylinder #8. If my engine were to shit #8 tomorrow, do I think Ford will cover my warranty? No.

Do I think Ford should make a bigger effort to figure out why their engines are ******** #8 on a simple tune that they had to know people were gonna do? They made an engine in their premier muscle car that was so weak it can't handle slight mods? I agree, bad tuning is a cause, but bad tuning would cause all sorts of different problems - at the very least, ******** cylinders other than #8. #8 is the last in the coolant loop, and it's the farthest from the knock sensor.

Furthermore, have you read the TSB? It's ridiculous. It directly intimates that if you but an axle-back on your car, the entire powertrain warranty is void. Excuse me? Magnusson-Moss? Anybody? Ford is pretty directly ******** on the aftermarket community with this TSB, and creating an adversarial atmosphere where, frankly, none need exist.

This is Ford from a decade ago, the era where we typed Ford as F***. Look at the bottom of the site. See where it says "This forum is not affiliated with Ford Motor Company"? That's because Ford tried to sue this forum because they felt we were infringing on their IP and trademarks. What kind of sad shit is that? Ford is so threatened by a tiny little forum for an obsolete car they took out back to shoot in the head that they were gonna sue us?

That's what's going on now. They are so threatened by the concept of bad publicity from a faulty engine design element they're trying to sweep under the rug that they felt the need to publish a three-page TSB specifically and unequivocally placing the blame for any damage as a result of said design flaw squarely on our shoulders. I'm fully aware of the concept of modifications voiding warranty claims for damages caused by said mods. I'm also aware that this is, to me, pretty obviously a high-tech repeat of the cam swaging issue.

The question is this: Yes, the tunes are causing the issue - for now. However, there's already been one case of a bone-stock engine with the same problem. Are these tunes simply foretelling the future? How many more stock engines are going to shit #8 in 60,000 miles once intakes are gummed up from the pretty copious amounts of oil coming through the PCV system? When they aren't running at peak efficiency? When the coolant isn't as fresh?

That's what I'm saying. If you have a problem with that, then by all means you have a right to that opinion - I fight quite hard for your ability to disagree. I'm not saying Ford is doing, legally, the wrong thing. They have lawyers with several million years of experience and the law on their side. Those actions, however, while legally correct, are not morally right. They are not doing the right thing on this issue. That's my opinion. And, having a $40,000 investment in their company for one of the cars in question, I think I have a right to it.

Oh really???

Yeah, it's got us Mustang guys all up in arms.

Pretty damn easy to read between those lines.

Mustang + typical Mustang owner + newly redesigned engine (with potential problems) + cheap tune = Mustang-boom.

If FMC has a legitimate problem at stock levels with said engine, they will take care of it. With such a new plant they will have problems.

How the **** do you think they can even begin to actually sort out the problems with so many people running tunes? This TSB seems to point to one thing for me. They ARE actively investigating the problem. And eliminating the chance of failure due to a tune is the first step at addressing it.

Simple investigative procedure in action. Remove any and all probable outside causes in hopes of finding the root of the problem. A tune has simply too many variables.

All something they HAVE to do. In this day and age everyone is cutting costs where they can. Utilizing it benefits YOU, not the MFG.
Why is it that so many people get "up in arms" about a MFG being more strict on their warranty stipulations? They are in a business to make money, not hand cocky tune running mustang owners brand new engines every time they pop one.

What I'm saying is that I'm not entirely certain that the tune is the only cause of failure of cylinder #8. If my engine were to shit #8 tomorrow, do I think Ford will cover my warranty? No.

If it isnt modified, yes. They are required to by law.

There is one clear and simple reason cars come with warranty stipulations. Accountability. A failure on a bone stock rig within the warranty time/mileage will be dealt with by the MFG. But any modifications to that rig that the MFG deems relevant to the failure or overall reliability of the vehicle will remove the accountability from the MFG, and place it upon you.

Clear and simple.

Dont like it? Go buy a Kia. I hear they have great warranties.

There's really no need to be a ********* about it. It's still pretty clear that you're not understanding what I'm saying. Read the TSB. Read the part where it says a CAI will cause the engine to explode. Where aftermarket mufflers will cause the engine to explode.

Do you have no business sense at all?


All that tells me is that they have had way to many modified 'stangs roll into the shop with broke motors.

They are sorting things out. But they have to weed out all of the failures due to mods first. ALL of the modifications. Is that SO hard to understand?


And *********? Really?

That's what I'm saying. If you have a problem with that, then by all means you have a right to that opinion - I fight quite hard for your ability to disagree.

Pulling that card makes you the d-bag.

For once I'm on Ford's side here.

The engine is advertised at 412 HP. It's a 5.0L.

The Ford Five Liter engine has come a long way since Shinoda tried to max it out in1970 at 290 HP. They only made about 7000 of those. The standard Mustang 302 made a measley 230 BHP.

for YEARS 290 HP from a stock, naturally aspirated 302 was unheard of.

Now, emissions standards are a hundred times more strict and the stock 5.0 make 412. And it's still affordable like a Mustang should be...And you wanna ***** about how modifying it voids the warranty?

Here...

I wonder how light you could make the car? Cause that's what you got if you want them to warranty the drivetrain.

Once again, I have never once stated that I expect Ford to warranty the engines that are tuned. Why do people keep saying that? There is a price to pay if you're an early adopter and want to tinker with the engine. What I'm saying is that Ford should spend more time figuring out why their engines are grenading with light mods and less time blaming it on the modders. Sure, deny warranty claims for tuned engines. That's how it should be done. But to publish a TSB saying an axle-back voids your power train warranty is ludicrous.

Also, the only thing the old 5.0 and the new 5.0 share is the displacement (and actually, the old 5.0 is a 4.9, so it doesn't even share that). Totally different architecture. People are getting 300hp out of a NA 3.2L V6 nowadays - technology marches on for all engines.

Do you have a link to a thread on the grenading of these new engines? I was thinking about purchasing a new Mustang but certainly would not want one if they can't be enjoyed. Would guess they would deny warranty on totally stock engines if Ford could prove that they had been to the dragstrip.

When this happens, is the engine salvageable, or does one need a new short block, or long block with new heads?

Interestingly, all of the cyl #8 threads on all 4 Mustang forums I frequent have vanished into thin air. I wouldn't be surprised if Ford was involved in that, too. There were at least two on each forum... and now, nothing. Weird.

In any case, as with the MT-82 problems, I think it's being blown a bit out of proportion. Less than two dozen owners have reported blowing #8 that I know of, and that's out of tens of thousands of mustangs over two years. The problem was diagnosed pretty early in the tunes to be that they were dialing down the knock sensor sensitivity. Every major tuner since has dialed it back up and sent out patches, and I haven't heard of any problems since then.

As usual, it's not the problem that's the big deal, it's the cover-up.
