O2 Simulator

[gooten1]

I know the domestics have these...they're for cars without catalytic converters (like mine). It sends a signal to the computer telling it that everything is hunky-dory in post-cat exhaust land. I need one, cause I really don't feel like spending $150 for a new O2 sensor that's just going to fail again.

put one on a 95 Trans Am and a code came up for "no activity". It has a set voltage and the ecm knows it should move some. wasted money.

Is your car OBD I or II? Active Auto Werk sells them for like $300 or so (I think).

man, for that you could replace the O2 sensors a couple times!

But not having a cat is priceless.....

until you go for emissions testing ... then it becomes "priceless" to replace i guess gooten is lucky enough to live where they don't check

Me too...one of the nice things about living in Wisconsin!

[gooten1]

Yeah, SC is pretty slack with auto-related laws. Don't blow anyones eardrums out, don't make the tint too dark in the front, but paint the rest of the windows for all they care, pollute as much as you want, just don't blow yourself up. Don't run over anyones kid. (=

But seriously, I will check on a decent simulator, and let y'all know what I find.

Did cutting out the cat make it Honda loud?What about with a stromung exhaust?

[AlaskaBlue]

It is loud. but in a good way. Just make sure to keep the resonator.

I've had experience with 02 sensor simulators that work. As for the m4x, I haven't found any. If someone could give me a breakdown of how the o2 sensor works it doesn't seem like it would be difficult to make a simulator.

[1rstbmw!]

Will cutting the cat off make it immpossible to re use again?and will it be outlandishly loud with a stromung exhaust system??

[pdxmotorhead]

If your careful you can cut it out and weld flanges on so you can re-install
it when needed.

FYI there is a element of hazard in this. If you get caught in a safety inspection
traveling across country you may find your car on the back of a tow truck
for illegally modifying a emmission system. The fine can be 10K dollars.
