*read write up above for full explaination*

the guy who did this, did it on a EP, but i'm wondering if it'd be the same for us. basically using a spark plug non-fouler kit to move the o2 sensor away from the direct flow of the exhaust gases from the motor.

makes sense to me...anyone want to give it a try?

 

Sorry, I have obd1

But, I don't see why it Wouldn't work, maybe someone should try it soon.

 

looks like it would work

 

i hope someone tries it soon. haha

 

it should work...evo and subie owners have been doing this for a while w/ no cel's

 

that will definitely work. thats no different than taking the second O2 sensor and zip-tying it somewhere outside of the test pipe. all you are doing is making it so no exhaust hits the second O2 sensor, tricking the ecu in to thinking the cat is working.

 

yes that will work. but if you dont have the tools or cant do it you should look into http://o2simulator.com/
i think a lot easier to deal with some wires

 

I bought the Casper Electronics o2 sim, bout 2 years ago, and still works good. cant member how much it was though.

 

yes this method will work for sure. i had it done on my 00 em1 for about 6 months before i switched to obd1

 

i'm just glad I have OBD I, much less hassels

 

most threads i've read about o2 simulators say that it doesn't even work. this has got to be a lot cheaper than a o2 simulator anyways.

 

o2 simulator seems like a waste of money when you can just zip tie the sensor anywhere outside of the test pipe...

 

im gonna try this somtime this week need to pass obd2 emissions

 

i have a 2000 integra.
i just ziptied my 2nd o2 to the car and pluged the hole.
works fine, been like that for 2 years.

let us know how it goes!

 

i dont know.. i would pay $25 (o2 sim) to make it look like i have sensors in the pipe. Maybe because Im in california..

 

I REALIZE it's not always the Honda way to DIY but: It's pretty easy to make a MIL eliminator for like... 3 bucks, I've done this for a few OBDII Accord's and it works fine. I started doing it after I bought my first 2G DSM years ago, this is the method they use to defeat it:

Obviously the wire colors are not valid for a Honda, but if you have a clue and a wiring diagram of the car it's easy to figure out.

 

i used the spark plug foulers, like the pictures showed, when installing my skunk 2 test pipe. when i first started the car up the CEL came on, so i said fu*k it, and about 2 months later the CEL just went off.

 

i used the spark plug non-foulers on my car for about a year with no problems. Took them out along with the secondary o2 after going obd1.

mechanical&gt;electrical anyday

the sensor is still in the pipe, and if a Cali cop looks under you car and sees a test pipe instead of a cat having a sensor pluged in or not wouldn't matter

 

Another option would be too elimianate the o2 sensor by getting the optimal resistance code from either a dealer or online, if you are interested i could get it for you. im me. But then you could wire in that resistor, to send false, but good info to your ecu. this way you could get rid of the o2 sensor al together

 

does anyone know if you can pass emissions w/ the sparkplug defoulers on the second o2 sensor???

 

Yes it works. I did that on my wrx (completely catless)
