Do it yourself o2 simulator
After a search I found that http://www.rodney.chalker.com/o2_simulator.htm
had a way to make your own o2 simulator. However, that site is down and I was wondering if anyone has those directions or know how to do it using a resistor. |

Re: Do it yourself o2 simulator
I will put it this way if you need new 02 sensors than buy them. Don't try to override them unless you have LS1 Edit and can eliminate them from the computer. If your computer has to read the 02 sensor don't try to make your own. You can't rig it up with a resistor.

Re: Do it yourself o2 simulator
Well i don't need new o2 sensors. I need an o2 simulator because I have a straight pipe in place of my cat. I've read before on the website I linked on how to make one but I can't remember how to and the site is down.

Re: Do it yourself o2 simulator
Ok I thought you said O2 sensor. The simulator is like $15 from Casper Electronics. Just buy one.

Re: Do it yourself o2 simulator
It works, and there is no need to cut any wires or anything...very easy as well.
I personally have driven about 300 miles since, no CEL. So anybody who wants to run a test pipe...here is the mod you should do to stop the CEL...don't bother with the electronic ones with only some of them working...and not working all the time. These pics are from it being done STi, but I did it on my S, works just the same. ![]() ![]() ![]() or ![]() Those are the Spark plug, Anti-Foulers you'll need to do this..just pick them up at any auto parts store This post has been edited by SLO-S2000 on Aug 21 2004, 11:11 AM |

Re: Do it yourself o2 simulator
Did this to my truck 3 weeks ago also and it works perfect. My high flow cat was throwing the P0420 code every now and then, sometimes it doesn't throw that code for months then out of nowhere it pops up, other times it pops up every few drive cycles. I still have the stock cat and i was about to put that back on there because i got tired of deleting the damn code (kept the obdii reader in my truck lol).
Since i threw the O2 foulers on, bam, no SES light. |

Re: Do it yourself o2 simulator
sry to chime in here with question but i too have a test pipe handy and would love to use it. so is all thats being done here is putting 2 non fowlers together and then putting the o2 into them, creating a larger gap between the cap/test pipe and o2?

Re: Do it yourself o2 simulator
from what i read online you can run a test pipe and it still wont throw the code. as long as the O2 sensor sees the heat then it wont throw the code.
Just to be 100% in a couple of days post it up if your light has or hasn't come on yet. |

Re: Do it yourself o2 simulator
Ok i've got the spark plug non foulers, and i'm looking at them and went to look for a 1/2" drill bit today... is there another form of a 1/2" drill bit? the one i found was freakin huge... like about the same size as the circumfrence of the non fouler bottom...

Re: Do it yourself o2 simulator
yeah... i got mine drilled out at a friends shop, he put the 1/2 bit on a lathe and it was close to the threads. you can almost see the indentation of the threads after you drill it out, barely any metal left... |

Re: Do it yourself o2 simulator
Alright as long as i make sure it's right... my stepdad has a uni-bit we can use, i'll probably do it tomorrow while we already have the truck up to do my calipers.

Re: Do it yourself o2 simulator
I attempted to do this tonight, I drilled out the fouler using a 1/2'' drill bit, and my o2 sensor doesn't fit in it. Anyone have an idea?

Re: Do it yourself o2 simulator
idk but how long does it usually take to bore out the fouler? Maybe i'm doing something wrong? I got the 1/2 drill bit and started to bore it out but after like 10 minutes of drilling in it on and off i had to quit(mostly to not be sweaty when i picked up my girlfriend), but i mean the hole in the middle didn't get any bigger but the actual surface of the fouler where i was drilling did get much thinner so maybe just go at it a little bit more with it? I knew i shoulda bought that damn unibit...

Re: Do it yourself o2 simulator
To answer my own question, the stock 02 sensors are larger than .5'', I had to buy aftermarket, and it works flawlessly.
As for drill time, about 5 min. I worked my way up to a 1/2'', make sure the bits are for metal too btw, and not wood. Having a nice vice is key for getting it done quick. |

Re: Do it yourself o2 simulator
man i don't feel like spending any more money buying another bit trying to bore this thing out. I tried with the 1/2" bit and the surface got deeper but the hole didnt get any bigger and i don't think it's making any more progress no matter how much i go at it. So i guess the CEL is just gonna stay off, at least until i can get to a better set of tools

Re: Do it yourself o2 simulator
Take it to a machine shop, they can easily bore it out more.
with mine i had it bored out to the stock o2 sensor size, the aftermarket i had in there went in with alot of room to spare. |

Re: Do it yourself o2 simulator
I think all i need is a unibit but it's 17 bucks at lowes and i really dont wanna buy that shit. My new rollpan should be here soon and when i take it to my dads shop to be painted and put on and have my door panel and window fixed, i'll use his unibit up at his shop to finish the o2 simulator. I asked him to bring it home a few times but the guy never remembers haha
