stillen intakes and fast intentions cbe tune?

luigi90210

why are you spreading false info?

the magnuson-moss warranty act states that the manufacture has to prove your modification caused the defect, if you go in with a blown motor and there isnt a problem with the tune(after extensive testing via dealer) they have to fix your engine under warranty, they cant just void it all together but they can deny a warranty claim if your modification did cause a defect

if i install an aftermarket radio and suddenly my speakers arnt working, ya my modification caused the defect but if i installed an aftermarket radio, and my glove box handle broke, they still have to fix my glove box under warranty unless proven otherwise(whether it is through misuse or my aftermarket radio)...

I am 100% aware of this, BUT, the information I spread is NOT false info... If you're saying your aftermarket radio controls your speakers, and if the speakers give out, YOUR modification caused caused the defect... The ECU controls the engine... Pushing it or modifying it outside of the factory specs, ANY tuning is considered "outside" the factory specs, because if the stock ECU notices anything it cannot correct by itself due to your mods, it will throw a CEL, kinda the reason behind a CEL...

When people ask what mods effect warranty I explain whatever you had to touch to install that mod, usually loses it's warranty (On intakes you'll usually lose the warranty on MAF sensors, on HFCs you'll lose the warranty on the O2 sensors)
No, you do not lose the warranty on the WHOLE car, I didn't say that, I just said at LEAST the engine... They can claim more parts are out of warranty (reason stated below) But yeah, you can have a different engine in your car, they'll still fix your window as long as you're under some type of warranty on that.
The only mod I know of that can't really effect your warranty in any way is a CBE (even though it kinda clashes with the other info I've posted below)

Also, the other beautiful advantage Nissan has, is that they can say, even on my car that has full breather mods, 'because my car has more horsepower than stock, I put extra stress and strain on the engine and transmission and anything really related to the drivetrain'. Now, if I have catastrophic failure, you best bet your arse that I'm reverting to stock, but when you revert your ECU back to stock, they WILL KNOW that. (Same with things like the MAF sensor, they can say I overworked it, or I overworked the O2 sensors or they got too fouled because the HFCs aren't as efficient as stock cats)

I do not mean to attack you, but since you're looking through my posts, on other threads as well, I am going to link that thread as well:
Be Careful with UpRev in Mass

And if a STATE can tell how many times you flashed your ECU and they won't pass your car for inspection, what makes you think corporate, who has to shell out THOUSANDS of dollars, won't do the same, and deny a warranty claim?

In the real world though, the ECU does correct some things itself regardless (see above, it will correct poor timing set by a dyno tuner). It probably won't correct bad A:F targets, although I don't know if anyone's tried that to be sure. Either way, the burden of proof is still technically on the manufacturer to show that you caused the problem. If the car has a defective camshaft from the factory that's going to snap after 10,000 miles, tuning the ECU doesn't change a thing about that really. Driving habits will cause a far larger variance.

Sure, Nissan has more lawyer-power than you do, but you also have the dealership on your side if you choose the right one. They're more interested in maintaining long-term customer relationships, and will spend the time to investigate what really caused the problem and whether they should push things in the direction of Nissan paying up or not. I haven't yet heard of a legitimate case (with any mfg) where ECU tuning caused someone to lose on the warranty when a mechanical manufacturing problem was clearly at fault. I'm sure if you dig around you might find a few, but you can find a few of anything on the internet, and those people just may not have understood how to work the system in their favor.

I agree that if there really is a problem with the engine when they manufactured it that the problem is STILL their issue, BUT just for an example as an extreme, if your car is TT and let's say the CRANKSHAFT breaks, they can say it's because you were pushing too much power, it is DESIGNED a certain way, and you are DIRECTLY messing with it, even if it just a tune, you still are modifying something the manufacturer didn't really design you to play with

On my first hand experience, BMW 535i was chipped, motor blew at 30k miles, and a few days later BMW HQ called and informed me that the car's ECU was reset but their black box had data logged a higher amount of air and fuel being dumped into the car over a prolonged period of time.. SOL

Another friend in Dallas had ONLY a NST pulley kit, one day was driving, pulley sheared... He reinstalled the OEM crank pulley and belt, and it was wobbling, drove to the dealer, the OEM cast iron crank pulley sheared! Now I believe the crankshaft was defective that even the stock pulley would wobble... But they proved he had an aftermarket pulley and corporate declined all repairs... Paid out of pocket for a new motor...

Again, the dealer, if you find the right one may be able to pull strings and pull some shady work so you keep them as your main dealer, and hell, they make money off a warranty engine swap, so they SHOULDN'T care... (If the dealer is accused of foul play, the dealership gets fined several times the cost of the repair) Again for a catastrophic engine failure, unless you REALLY do have a great dealershit (Brandon, you have Baker North and South, so you're taken care of) you're gonna be SOL by tuning your car when it's warranty time


So if you're willing to bet your $500-1000 tune plus the cost of a new motor for the extra xHP, and no throttle delay, which I haven't experienced, and the ability to take your limiter off so you can go 200mph, by all means, do it...

Hell, I'm an Econ major, by all means tune your car, 99% of the money you pay goes into Americans' pockets, it supports the economy!

In my opinion the stock ECU will adjust the A/F ratios enough to get the best HP out of your mods if you give it enough time to adjust, making the effects of a tune minimal
