O2 Sensor Simulators?

Anybody know where I can find some O2 sensor simulators for an 09 5.7 to shut off the CEL? Trying to do some research on my own but itís hard to find anything vehicle specific.

Why not correct the issue causing the CEL being on?

Don't limit search to jeep - maybe the dodge* side of Mopar is more likely to deal with this type of wonderful idea.

* lots of hemi's in their lineup.

When I see the price of OEM I think aftermarket.

So, what's the CEL code(s) and what have you done already? What type of exhaust system do you have on it? Any leaks ANYWHERE in the exhaust?

Donít have a code yet, just anticipating having one in the future.

I cannot think of a situation where eliminators would be advised or help.

He's talking about the post-cat O2 sensors. And you typically run them when you cat-delete or hollow out stock cats. That's why he wants them.

WHY would do that on a street vehicle?
the o2 sensor would likely send skewed readings..

Or if you have long tube headers and high flow cats.

Look up spark plug non-fouler. Dorman makes a few.

The non foul option doesn’t work on these long term. I tried various lengths, bends, and various amounts of steel wool to fill them. The best way to solve your issue is a custom tune. HP tuners, or a predator platinum with a custom tune will take care of it. Hemi Fever tuning is a good option.

The post-cat sensors donít affect any type of performance, they only monitor whether the cats are functioning correctly. The pre-cat sensors are what alter air/fuel mixtures and other things depending on whatís coming out of the headers. If a post-cat sensor throws a code, thatís all it does. Doesnít change anything performance-wise.

To cut the CEL off.

I was getting codes after installing American racing long tube headers. I used Vibrant Performance O2 Sensor Restrictors Fittings with Jets VIB 11621 to clear codes I was getting. Been a while and forget the actual code. I think I got them from Fasthemis.com.

You have those long tubes installed or do it yourself? What kind of performance and fuel economy gains you seeing? I just had a MagnaFlow 11229 muffler installed and my mileage went up 3-4ish mpg. That stock muffler was crazy restrictive, I can only imagine why the stock manifolds and cats are doing to it as well.
