Ok, my header is on the truck coming, very shortly too might i add, im installing it either monday or tuesday when i have off but im doing some research first, since the pre-cat will be coming out, and everyone says it will throw a CEL code, im wondering where can i get a o2 simulator, or antifouler? im not to sure what antifouler is and ive done a little research around here but cant find anything with some good information about getting the ecu to not throw a cel

help me out here guys :)

from what i understand an o2 simulator is your best option. antifouler will not really fix the problem, just covers it up. where did you order your header from? they may carry the o2 sim since they are selling the headers.
if not i'm pretty sure creative compacts sells them. if you don't see it on their website call the 800# cuz i know they carry it

how hard is the o2 simulator to install? and um creative compacts doesnt have it on their site, bah! lol how much is a o2 simulator anyway?

I have knowledge on american cars but not imports :doh: but im getting the hang of the whole import scene now too! :) lol the header install itself will be pretty easy but the o2 sensor issue seems to be whats gonna be a little harder, if i install the header itself, and figure out where i can get the o2 simulator from, could i get a shop to install it?

o2 sim works good but if you want to try and find anti fourlers they are normally for spark plugs and you can get them at your local auto parts store. I think the size is 18mm and most people stack two on on top another. also with the search button i found this

Hope this helps

i'd rather do antifoulers personally. they're much easier and work just as well if not better

anti fouler works with my alphawerks

zpi has o2 sims for 100 i think

the antifouler doesnt not cover up probs. they actually try and fix it but its not succesful because i believe over 80% of the anitfoulers on here have thrown a CEL.

o2 sims cover up probs. o2 sims are designed to cover up and make the ECU think everything is ok or it feeds the ECU data to run the correct way.

you can get an 02 sim from AW for cheaper than 100 i believe. mine's from AW and it works great

some people said alphawerks own o2 sim didnt work..but then again i found out all o2 sims have their lemons

ANti-fouler www.clubsciontc.com $20 THey are great and fast shipping!

Great customer service as well i might add !

make sure you wear clean latex gloves when you handle the header

Haha yes indeed!

antifoulers worked for my RSX. no CEL with race header. now i gota install my alphawerx header and hope i get the same outcome.

be extremely careful when handling o2 sensors. i somehow busted my primary o2 on my rsx when installing my header but luckily dealer replaced it out of goodwill.

if it throws a cel on tuesday, and i cant get to bypassing it, is it something i should worry about, will it harm anything or no? because i might not be able to get around to the part i need or the time to do it on tuesday and i need the car wednesday for work


oh and btw with the CAI i am at about 180 miles with a half of tank of gas to go! woo and i get my first oil change tomorrow!

www.thescionstore.com

here you can find a O2 simulator...

i though that the alphawertks header was not supposed to throw a cel?

thats becosue they give you an o2 sim with it atleast they used to

how the hell do you get the the downpipe bolts off, i cant figure out how to get them off, i tried all kinds of stuff on them, and i still cant get them to come off no matter what i try i live in southern jersey, someone should swing by today, i live in delran, right off of rt 130 and i really need some help with getting this header done today, i have about 5 more hours before im completely screwed :( help!!!!!!!!!!!!!


NM Guys its installed, torquing down my ____ and then im gonna double check and fire my baby up :0 lets hope it sounds amazing!

hahaha good you got it installed


check engine light?

I have anti fouler mod and my check engine light has came on twice i just keep restarting the ecu.. How do i know if it is my o2 sensor that is bad? If it was bad would the cel come on after about 200 miles or imediatly?? thanks............

Why would you buy something that gives a cel code?

A cel code means you car is not running right.

An antifouler is a Bandaid way to go about the problem.
And a Simulator is also.

Why dont you figure out the problem and fix it?

the cel a header throws is 99.9% of the time catalytic converter out of threshold. does YOUR header not throw a cel?

I have the new Megan Header along with racing solutions s-pipe and installed the antifouler and no CEL, I'm about 3K miles now.

Because, the CEL indicates emissions failures, not actual problems w/ the engine (for the most part). The car is still running perfectly fine, it's just that the emissions specs are not up to the stock sepcs.

yeah.... So how do i find out why i cel keeps poping up with my antifouler installed??

get the code read. post pics of the antifoulers installed.

OK i will have to wait till my cel goes off again. But if my sensor was broken it would went off before 200 miles right?

yup

well before my car got vandalized my cel came back on about 200 somthing miles after i restarted my ecu.. WHat could the problems be?

Did you install the LONG THREADED SHAFT Anti Foulers? Part # 42002
I believe that the short shaft antifoulers do not space the O2 sensor far enough away from the exhaust flow to read a reduced flow rate in the pipe.
Remember to drill a 1/2" hole through ONE of them then screw the drilled one into the non-drilled fouler then install it in where the 2nd O2 sensor is located.
The long foulers have been installed on my car for 1K with no CEL in sight.

I have the one from clubsciontc and i installed it on the s-pipe cel comes on every 200 miles.
