I was browsing E-Bay the other day and came upon this:
Universal MIL Eliminator, O2 bypass, Simulator
a while back I asked if there was anything I could do to trick my downstream O2 sensor to prevent the CEL or my car to run like "isht" when I would remove the "CAT".
(2003 Outlander AWD)

Let me get to the point here:

-want to gut my "CAT" to keep the oem look,

-wonder if this "MIL Eliminator" will do the trick?

I thought the air/fuel ratio was not the same all the time, I though it changed when you accelerated har, etc. Can anyone clarify for me? The reason I mention this is they state it will return you to a "perfect" ratio of 14.7/1

Is 14.7/1 really a perfect ratio??

my point exactly...I don't think a stoichiometric air fuel ratio is ideal, although most cars are delivered from the factory to that setting. Although if you have a piggyback modifying your ratio you are good to go. The 14.7:1 ratio is the best ratio for emissions. The best ratio for power is 12.8 to 13.2:1- roughly 13 parts air to one part fuel. A fuel economy mindedratio for fuel economy is 16:1, hopwever stumbling and poor idle will begin to occur at this point.

Pretty good article for people like me- explains air fuel ratio and the help a wideband O2 sensor can provide to gain optimum performance.

Well I found another one of them:
MIL-eliminator

I talked to the mechanic that worked on the exhaust on all my cars and two weeks ago he installed one
of these "MIL eliminators" for a guy on a Lancer with an after-maket exhaust system.
He said in his own few words "the little piece of isht seems to be working just fine".

I've decided to gut the cat this weekend and use this item on my O2 sensor, I'll keep you all posted how it all went.

Thanks for all the input.

Makes me want to get all technical with my car....lol
I'd like to have a wideband and the ability to modify a/f ratio to see what the gains are for just that alone. I believe that's what the piggybacks do for the most part is modify the a/f ratio. Is this correct?

Optimat, let us know how it works for you, also if you lose any bottom end power or where there are any noticeable gains.

I finally got of my lazy but and ordered the part, it should be here within 4 days.

With any luck I shoul hack up my cat next weekend, and post some insight on the project outcome.
