I just reordered the pypes o/r H-Pipe and I wanted to know what would be the best way to get rid of the CEL when it comes up after I install the H-Pipe? I have a preadtor Tuner, Will that do anything?

 

Contact whoever you bought your tuner/tunes from and have them send you a new tune with the rear o2's turned off.

 

You may not even get it. I didn't! You can also order MIL eliminators from Brenspeed, but I would wait to see if you even get it first.

 

Lucky I got my CEL on the first day.

Jersey-Don't buy MIL elminators since you already have a tuner and it won't/shouldn't cost you a dime to have your tuner turn off your rear 02's.

 

Oh yah, he already has the tuner...

Yah, dont' buy the MILs...my bad

 

Thanks everyone!

 

I'm interested in how the MILs will work, because here in my county (Travis & Williamson of central Texas), they have emissions testing, and the analyzer will see the O2 sensors (among others) are "not ready" when turned off. Even tho they are turned off now w/ the CAI tune, I won't have the option (read won't take the time) to go to stock every year once LT headers are in place. So I need the O2 sensors ON, and hopefully the MILs will keep the ECM from capturing an error code. Has anyone tried this, and can verify it will work?

 

Re-ordered? Changed your mind the first time around?

Can always put a pic of your g/f or wifie in front of the CEL.
Seriously, do what Leo suggested.

 

Jim, I'm confused with your situation.

If you're subjected to emission testing, just having the O2 sensors 'on' won't do jack if you have LT headers installed. Your emission levels will be off the chart! Believe it or not, that catalytic converters actually do something and this is where the rear O2 sensors are screwed in to.

My advise is if you don't want to be swapping out your LT headers every year, get a shorty that's 49 State legal or keep your stock manifold. Downstream, if you go the O/R H or X route, you'll need to swap this out with your stock catted H prior to your emission testing.

On your CAI and tune, depending what CAI you have, you may need to re-install the stock airbox and reflash it back to stock in order to be within the emission level limits.

Bottom line, MIL Eliminators are not the answer to everything, especially emission testing.

 

MILs are the way to go, IMO. But wait until your emissions have been checked before puttying your O/R pipe on. Then remove your O/R pipe when its time to get your emissions certified again. Alot of places only check to see if you have any codes. But I think any honest emission tester will be able to know whether you have cats or not. JMO. You might be able to get away with it, but I doubt it. The worst thing that can happen is that you take it home and fix it and pay to have it retested again. Right?

 

you can turn the O2s off with the predator]

MIL eliminators are for chumps and the uneducated

 

My plan is to install the Amer. Racing LT headers, with their own little hiflow catted X-pipe.

When talking to the emissions inspector, he said he just checks to see if cats are present (not if they are stock or not). Then he hooks up the analyzer to read if there are any codes in the ECU. I failed my emissions test 2 weeks ago, 'cause I had a CAI and custom tune loaded that turned the rear O2 sensor off. Thus the ECU told the analyzer the O2 sens was "not ready" along with Cat sens, evap sens, and O2 heater sens (WTF that is). Anyway, I swapped back to stock air box and tune, went back, and all but "evap sens" was now "ready" and no error codes.

So what I'm hoping, is after install of LTs and catted X-pipe, I can turn the rear O2 sensors "on", and then use MILs so the ECM doesn't get sent a voltage that will light up the CEL, while allowing the ECU to think the O2 sens stuff is all "ready" and functioning.

 

MILs are good for times when you have to reflash to a stock tune and you don't want a CEL. Like when you take the car to the dealer to fix your !@&* TPS sensor fault under warranty.

One is a hardware solution and one is a software solution. I prefer hardware.

 

 

I have the same mods as you currently(C&L Racer,Flows,Brent's Tune),and I am planning to do the AR LT's with Catted X too.

PM official_style,he has the same setup that me and you are planning to do.I PM'ed him and he said the AR X & LT's made his exhaust have all drone eliminated.The sound is deeper, louder, alittle bit raspy,and it is quiet until you mash the pedal down so it seems that his car is a sleeper, so thats cool.

 

No, really, tell us. How do you feel about MILs ?

 

You can get MIL eliminators for $11.95. Why knock an inexpensive mod? Believe it or not, but alot of people don't own a tuner yet.

 

I wish I got the pypes first, I was stupid enuff to buy the JEGS O/R H-PIPE!!! (BIGGEST REGRET ) They sent me out some stupid a$$ pipes that had 4 02 holes! SO BOOTLEG! I just sent it back today and ordered the PYPES from Brenspeed. Also, Thanks bills for the how to do hotlinks, Im gonna install the pipe based on that.

p.s. How high did you raise the car up?

 

put it this way, enough to get under the car, some rhino ramps work or on jack stands
