Has anyone bought o2 simulators that work?
If so how much were they and where did you buy them?
Thanks in advance!

 

Properly called "MIL Eliminators", these devices are intended to simulate the operation of functional cats and to prevent P0420 and P0430 OBDII codes. They still require all four O2 sensors to be fully functional.

Nothing more.

You can make your own for less than two bucks using parts from Radio Shack.

Google or SEARCH this site for "MIL Eliminators" to find sellers or to find instructions on making your own.

I bought a set from "thebestmileliminators" off ebay. They were less than $15 dollars. They have worked perfectly for over 20,000 miles. Just be sure to order the "2 wire" kind. I initially bought the 1 wire kind, but they wouldn't work on my truck (don't know why??). So he sent me the 2 wire kind for free. The work great. And they have a 1 year warranty.

I remembered this guy's website. He's really nice, and will help ya if you have any problems. http://www.killswitchcentral.com/index.htm

 

That guy has several untruthful claims about his MIL eliminators...... About the only one that is accurate is that they will keep the MIL off if the converter is gone (or inefficent). My choice of words, not his. I'm trying to be statesmanlike...

WHAT????

If this is what you're talking about.... I've talked to him before... I don't think he quite understands what's going on with the A/F ratios.

 

Radio Shack worked for me. I think it was a bit over $3.00 and I had enough parts to make 3 sets. One set stayed on an 04 Stang for about 6 months before the car was sold, another set were put on my 01 in the begining of 02 and up until I sold it in November they were working fine. THe last set that I had are on the Mach 1. They have been there since it was new in 03 and no problems yet.

I have seen alot of people use the plug ins and the splice ins that you buy and have problems with them not working sometimes.

 

All WRONG. The sensors that MIL elimiminators connect to have NOTHING to do with A/F ratios.

Well, since these sensors have NOTHING to due with A/F ratios, I guess he's right in that they won't affect any performance chip or programmer..... However, it's pretty lame to make this claim.

Try this on any 96-on Ford and see how long it goes with only his device installed before the CEL comes on. Maybe he means you can just leave the sensor tied off somewhere....

Since MIL eliminators have nothing to do with A/F ratios or anything else to do with the running of the engine, this claim is an outright lie. So much for statesmanship.....

Why would anyone doing offroad only care if the MIL/CEL was on due to catalyst efficiency codes in the first place?


You get the picture...hopefully....

Wow that is over my head. I guess I am buying the pre-made 8$ ones.

 

Yeah it sounds like he is confused on what they do. But as long as you bought his product and they stop your mil from coming on then I'll buy them.

 

To be honest it really isn't that hard. Don't worry about using the DMM, and don't bother with the PC Board either. Use this illustration, all you have to do is cut the gray wire and solder the resistor in then solder the capacitor in with the harness side of the resistor. You can use the soldering iron to burn a bit of the rubber off of the black wire and then solder the capacitor to the bare area of the black wire.

Here I made the diagram a bit easier to understand. Its pretty simple cut one wire and make 3 solder connections.

That's the same design that the ones I bought had. The 1 wire kind didn't work on my truck.... I don't know why, and neither did he... He said that he'd never had a problem with them, so he sent me the 2 wire kind (like in the illustration) and they work great!

 

Yeah I definatley understand this one! Thanks for your help.

 

Had my clogged junk rattling cats removed finally. The mil still hasn't came on at all. So it looks like I don't need the parts I ordered from radio shack. I can't believe how much louder my truck is now it is as loud as my buddies chevy with true dual straight pipes, and all I have is a si/do flowpro powerpack. wow
