From what ive searched ive found nothin but things like anti-foulers that do nothin but jus turn it off. I dont know about eveyone else but i would much rather have a TOTAL fix not jus pushing the other aspects of a CEL to the side.

Unless i missed the thread or didnt word the search properly to find a thread stating thats there is actually a o2 sim that works i havnt seen anything. The cars been out for awhile now and nothing...

ZPI tried but stopped making/selling them after seeing that it doesnt work (found that out first hand >_<) But wonder why they didnt try and fix and keep testing to get one that works.

I hate it lol i like the header jus hate the damn CEL and what it causes...i know about the MMW fix but as far as i can understand it does what the anti-foulers do an is not a complete fix.

Point of this is did i miss a thread from searching that says who has come out with a good complete fix for the CEL? or am I along with everyone else that wants a total fix screwed...

 

Whats wrong with the anti-fouler fix? It turns it off.... no harm done to your car. What the problem?

 

Can you not just relocate the 2nd o2 behind the 2nd cat?

 

the reason for the 02 error is the lack of cats in the exhaust.....but what your saying would work, if he had a cat in his exhaust...

but most aftermarket ones do not, and no header(that i know of) has a cat in it.

 

ok but what i am talking about is how it runs rich, and with the anit-fouler it just turns the CEL off but still runs rich correct?

plus ive noticed since the header has been put in it shakes more than it did before. It doesnt shake violently just annoying...

 

I have the full chromed out draxas exhust w/ hi-flow resonator, so not sure...

and also does anyone know if the MMW CEL eliminator work and work for other headers and sold seperatley?

thanks in advance...

 

the o2 simulator is just like having a anti fouler, it won't tune it to run clean, it just gets rid of the CEL. the anti fouler is just a cheaper way to do it. do a search, a few days ago someone posted a place that sold them.

 

o2 simulators from what ive been told are SUPPOSE to be a complete fix..not just take away the CEL...

and i dont need to search i know where i can get CEL eliminators, the question is which has found to work the best...because ive read lots of ppl it hasnt worked for when i searched on this subject...

so plz if u arnt going to answer my question then plz dont post at all...i have searched this subject many many times...

thanks

 

from what i have heard, the first 02 is what the tc tgunes off of...so the second 02 is only used to show that the pre-cat is not working properly

 

The reason why many companies are not dealing with this issue is because of the EPA. They are cracking down on the industry for stuff like this. That is why Casper stopped making and selling them too.

 

So is the 2nd o2 sensor really important? or can it be replaced with, oh lets say an AEM uego lol

 

I have yet to see it be done personally. The 2nd O2 sensor measures cat efficiency. That is important to the EPA and emissions testing.

 

OK the first sensor is an Air/Fuel ratio sensor some would call it a wide band O2. The second sensor is just a regular O2 sensor or a narrow band O2. The only job the second sensor has is to monitor the exhaust after the cat which is located in the manifold that you took off (if you have a header). If it's not there then it thinks it's not working properly and throws a CEL. Anti-Foulers work for some people sometimes. Personally I don't like tricking the ECU but that's just me. The ONLY thing you can do to fix the problem is to add an OBD II compliant cat and relocate the O2 sensor behind it.

 

True, however in CA and a few other states you can not relocate a sensor AND/OR use an aftermarket cat at all on an OBDII vehicle.

 

You are correct. Just to add to that it's also illegal to remove a working cat from any vehicle in all 50 states. So in Cali you're toast either way.

 

100% correct.

 

As far as I know, the CEL causes the car to run rich. So if you turn off the CEL you don't run rich.

When I install my turbo kit I had a CEL for couple days until I was able to install the anti-fouler plugs and the CEL went away. I also run the AEM wideband to confirm that I don't rich because of no cat.

 

^^That is correct. Air/Fuel is monitored and changed by the stock ECU, so a CEL indicates a problem, generally causing the car to run rich or lean b/c of more or less airflow, or a sensor missing so it cannot take readings. If an Anti-fouler cancels the CEL, that tricks the ECU to thinking it is running at nominal (normal) conditions.

 

Older OBDII systems it would work fine on but I found out with my car that it didn't, the reason why is because my car is CAN Scan OBDII its a new version of OBDII. CAN stands for Controller Area Network and it sends data at extremely fast rates not exactly sure how much faster but at a minimum its 3 times faster. The computer has close specifications for every sensor and even closer than regular OBDII so its extremely hard to fool because of this. I had to relocate the second sensor behind the cat on my custom mid pipe and no more cel problems.

 

I have the CEL, and my car runs around 14.5- 14.7... cause that's what the ECU does, change the mix to achieve this AFR. It runs richer at WOT to help cool off at the higher RPMs.
