Headers without a tune?
 

I purchased the Borla UELs but I don't want to get a tune and void my warranty. Ft86speedfactory said it shouldn't be an issue, but I am a little worried that the engine might start running lean. Can I still run them for the next two years until my warranty runs out before getting a tune?

Buy the openflash tablet. Flash to the stage 2 Uel tune. If you need to go to the dealer for warranty use the oft to flash back to stock map. Takes 10mins to flash.

There is no flash counter? and is there a tune for my Borla UEL, Nameless DP/OP and TRD Ctback?

Also curious about the flash counter, I know GM and Ford have been doing it for a few years now.

It's an n/a car...you don't *need* a tune for performance parts. It will run just fine.

I've heard about this mythical flash counter and I have yet to see any evidence for it. OP: minus a header, you don't need a specific tune for those as they don't do anything except add volume to your exhaust. The Stage 2 UEL tune from shiv will work fine for what you have.

While you may not "need" a tune, depending on what you mod you may end up with worse performance, worse mileage, or a poorly running engine without tuning for the mods. Anyone suggesting running a catless header without tuning for it obviously does not know what they are talking about.

you dont want to void your warranty with tuning but you bought headers that removes emission equipment?

I agree with Malt. Even if the mythical flash counter does exist, it's not something the dealer can just check on a whim. From what I understand, they have to send off your ECU to be inspected.

And at that point, something CATASTROPHIC must have happened, since the dealer is willing to go to such lengths in order to deny you warranty work.

I say buy an OpenFlashTablet, flash shiv's Stage 2 UEL Tune, and enjoy your ~25 more horses.

If needed, flash back to stock and remove your headers before having warranty work done.

6000 miles, 3 track days, and a bunch of autocrosses with JDL UEL catless headers, over pipe, catted front pipe, Invidia catback, and an O2 spacer for second sensor (with the occasional CEL but very rare) on stock ROM.

There was an improvement in power over stock, as much as with a tune? Surely not.

You already voided your exhaust component warranty by installing Borla UELs....

To avoid any engine issues, you should get a tune for safe operation.

Use the stage 2 uel tune. ALL TUNES INCLUDED FREE OF CHARGE!!!!!!
Best $500 I have ever spent on my car.

You definitely want a tune with a header. It will usually double (sometimes triple) the gains you get from header alone.

Header without the Tune is like Cereal without Milk.... It works, but works better with the other :).

I ran the RevWork UEL for a few months with an O2 spacer and without a tune and still got a CEL. You're already voiding your warranty by replacing the headers.

I highly recommend getting a tune. You can probably get away without a tune, but not for very long. You risk running too lean and possibly blowing something

No, you aren't voiding your warranty with headers. Nothing "voids" warranty, they can just deny you. He will be denied warranty for exhaust components, but nothing else.

I know I have read it several times on this forum but do you know what the name of the law is that prevents dealerships from denying warranty because of aftermarket parts?

Mistake

They have to prove that the exact part caused the problem. They can't tell a guy who has a turbo on his car that they won't replace his taillights with condensation because he put a turbo on. It doesn't effect that part. But if something was wrong with his engine or transmission that they could prove messed it up, they can deny.

yea cause the headers wont void the warranty. thats a totally good idea to not get a tune. dont wanna mess up your warranty.

Another ignorant post. :thumbdown:

i was just kidding. not trying to come off like that. ppl here already answered his question. header will work but kinda a waste with out a tune. for warranty, tune is easier to hide than a header (sound, you can see it).

HEADER ~$600
TUNE ~$600

$1200 Header/Tune will get u maybe 16hp-25hp $75-$48 per 1hp
$600 Header alone will maybe get you 2hp-10hp $300-$60 per 1hp

Cheap headers are 600... real quality headers are nearing 1 grand

OFT+OFH 1k

OFH </> JDL, FT86SF, P&L

JDL, probably not although tuned vs tuned, not much difference between the 2.
P&L no idea.
FT86SF, non-tuned yeah but AFR looks like dog turd, tuned, not quite. Not in the same league as JDL either.

So 1k for header+tune with more performance vs header with no tune in terms of price, OFT+OFH can't be beat. You also get gauges and logging plus can learn tuning and make other adjustments specific to you car and use it to flash.

Pretty sure then entire point of this thread is talking about Borla headers lol thus the $600 mark he used in his example is valid. Your comment, not so much. We're not talking about any other headers

i kno. i was just saying 600 cause he got borla ~600

Where do you see the AFR for the FT86SF headers?

In its thread.

yes belive it magnussen moss act or somthing similar
however in the end it going to come down to you, usually untrained without experience or qualifications arguing your point against qualified trained personel with the backup of automotive engineeers and lawyers and a big budget.

If you change your header you have altered the gas flows changed positioning of 02 sensors possibly removed cat, increased power output changed afr ect. You have probably removed heat shield so any melting deterioration of belts hoses or other components due heat from aftermarket headers would be most likely denied.

And thats if you were not running a tune or they did not find it.

Your chances of any engine warantee would be slim if they could find or argue that the problems were caused even indirectly by header or install. Even something as simple as an exhaust gasket leak near 02 sensor will cause incorrect readings and throw your afr and fuel trims wildly off. Or damage to 02 sensors ect

It would definitly risk denial of warantee on many engine related issues.

Not to mention people buying and thinking stuff would be carb or emission legal just by having a cat with no proven data. Sounds legit.

Not everyone lives in a state that checks for that.

Thank God I don't live in Cali... my E39 is catless and passes emissions :bellyroll:

in the county where I live here in WA, no emission laws.

Doesn't matter if you live in a state or county that checks for it, tampering with or replacing a functional catalytic converter is against federal law.

It's also unconstitutional that I have to meet certain requirementes (earn X amount of money or be a father) in order to have a concealed weapons licence, but I can't do shit about that.

If you can explain to me what a concealed carry license has to do with catless headers or tunes for ECUs I'd love to hear it, otherwise keep the politics/gun crap out of here.

basically coming down to stupid federal laws that make no sense...

Let me see, you say that even though a state doesn't have emission laws its against federal laws, then I say that a local state law is anti-constitutional but is still enforced, to prove that states can do whatever the fuck they want with the laws and you want to keep politics out.

Good info in this thread.
