Because we can...

and:

Because the Magnussen Moss Act is still in force.

That's why.

I agree with ag. Pay to play, if you screw your truck up with a tune, it should come out of your pocket to fix it. If not ford just passes the buck onto the consumer with increases in new vehicle costs.

I tuned my ecoboost with under 1000 miles. I don't hot rod or race just love the extra grunt and trans tuning. If aftermarket tunes were causing any Ford motor to blow with regularity I many have thought differently. Engine failures either tuned or stock are rare. My .02

Sure, and good luck to you if you have any issues with any part of your drivetrain because I highly doubt you have the engineering background to be able to prove that the tune did not cause the problem if one should occur (whereas Ford has a lot of engineers who can most likely run the calculations to show that the tune was the culprit).

I love how people think they can hide behind Magnussen Moss as if it means they can do anything they want and cannot be denied a warranty claim. If you are so protected by Magnussen Moss, why not leave it tuned when you take it in for a problem? Why try to hide what you've done?

I don't own much that is stock. Why? Becuase they build everything for the masses. They need to build something that will not only make some young kid happy who trips and falls into a bunch of money and they need to still make someone who buys as a retirement gift happy also, they need to find the balance. I customize to make it mine and to suit me, if you don't thats fine.

The Magnussen Moss Act protects the buyer. Let's say they build a lemon of an engine and decide they don't want to warranty any of them, but they notice that you added a different 4x4 sticker, changing the drag coefficient, adding extra wear on the engine and the reason it blew. Thats going a little on the extreme side but it keeps both parties honest. FYI I keep my tune on my truck when I take it in, hell the service manager asked the brand and some contact info because he added the same one to his personal truck. Now I'm not going to complain if I am burning tires off and smoke the transmission, it is what it is and I pay for it, but lets say a power seat or my radio doesn't work, then yes I would expect them to fix it regardless of tune.

What problems can a tune cause anyway these days? Sure, you can fry your PCM. That's pretty much it. So I tuned my truck.

Just stay away from banks, bully dog and superchips IMO.

Still not as bad as Audi has gotten, for major repairs, the audi/vw scan tool will download your ecu and send it back to the motherland (AoG - Audi/Vw of Germany) and if the ecu parameters are changed by any means you get a TD1 code applied to your vin. Td1 = ECU modification and entire powertrain warranty void. Previous companies such as APR had extra memory allocated for "stock" mode and you could switch to that, lock the ecu and go unnoticed, so AoG started downloading ECUs. The only way is to flash back and they dont really monitor flash counters as most tuners reset it to what it was originally prior to flashing the problem exists if catastrophic failure, you have to tow it to the shop that did the flash, flash back, then tow to Audi. Fried ECU you are just SOL and AoG has the only set of computers that can program new ECU, so the days of hot swapping ecus are even long gone.

Sure MMA exists, good luck, the guys over on Audizine have had a hard time proving that to Audi. Audi goes, warranty plainly states upon buying the car any ecu modifications are a direct violation of the warranty and will result in a powertrain warranty void and repairs may or may not be warrantied and if you want to go to court, we will see you there.

Once TD1'd it can not be removed and this can not be applied manually by service techs such as for intakes and exhaust, audis version of skynet does it.

MMA mainly protects people with intakes, exhausts, intercoolers and so forth. ECU tampering of any sorts basically does not need to be proven to be the problem, you tuned it, your tuner couldve put something out of "our spec" thus your problem. They have no way to read your programmers code to see that he didnt botch a line of code all they know is, someone messed with it and that is all that matters. Now you need to prove your tuner vs Ford or audi or any manufacture for that matter isnt in the wrong.

The only thing concerning me is the condensation/random mis-fire problem. If I tune and have this issue come up I want to know is Ford going to deny warranty b/c of the tune. In my mind they should not, but I've dealt with GM too much before with a bad rear end in a TBSS that was tuned and got the shaft. I'm a hair trigger's pull away from buying an SCT, but still a little hesitant to do it due to this. Great thread with some good answers so far, so please keep the answers/opinions coming.

Dont get me wrong, I understand the protections intended by M-M but I've seen way too many people do things like put 35's on a mid-size truck, grenade the front diff when swap back to stock to try to get it covered under warranty.

From the standpoint of a tune, Ford could very well be justified in voiding the entire drivetrain if something were to fail after you added a tune because there are tunes out there that provide huge torque increases for the EB which could potentially put a component beyond the design criteria (and just because one truck is fine after the tune does not mean they all will be, the one that has no problems could just be on the high side of the design tolerances while one on the low side could break).

Look at the early tunes for the new mustang 5.0, lots of issues because (from what I understand) some tuners were ignoring knock sensors. No way Ford should even be asked to warranty that but too many people lack the personal responsibility to own it rather than trying to scam the big corporation into paying for the fix.

Oh I know all about the act and no I don't expect them to cover if I push the limits of a component. Ford leaves a lot on the table to make it an all around engine, I chose to go with a tuner that has a reputable background, waited to see how their tunes worked, and paid a little more for a named shop to do it and not some guy that bought the SCT package and doing tunes out of his basement for $50.

I have a heavily modified snowmobile for riding in the mountains, I said I am keeping it stock to the wife when I bought it but it was down to the bulkhead after being in the garage for 3 hours, it's how I am haha. The 800cc now puts out close to 180hp in a twin 2smoke, if I blow it up I know I am on the hook for a new top end possibly cases and a crank, build it bigger and better next go around. BUT, if say polaris has an issue with say a suspension component or wiring or something else, you better believe because of MMA I am covered.

I agree some people abuse this act or think it will cover them, but honestly these engines have a lot left in them, me running the right tune and right fuel I know I wont have any issue for the life of the truck due to a tune and especially with my driving style. Luckily for me my dealer agrees something minor as a good tune that they will cook me later if I need something done on my truck that is reasonable.
