No they don't. If you don't get a CEL in the first littel bit, you will probably never get one. I have been installing mechanical CEL fixes on my customer's cars for years. Some cars need 2, or the 90 degree bung method works as well.

I like the anti foulers better than the soldering method. The mechanical method can never fail.

REALLY, please elighten us as to who accomplished this.

How hard is it to understand.. 1 or 2 antifoulers move the o2 sensor far enough out of the exhaust stream to not throw a Cat Inefficiency CEL when you are running catless.

I've used this method on hundreds of cars.. Subarus, Evos, Toyotas, Mustangs etc.

I did this on my WRX about 6 years ago. I didnt know about antifoulers then, but this was cleaner.

YEAH, thats cool and all but what you fail to realize is the LEARNING ecu that will eventually catch on and prove my point......

Rockland,

Your ECU is not scouring the internet looking for proof that you have screwed with it.. and throwing CELs when you wake up in the morning.

What you fail to realize is how an ECU works. ECUs operate on voltage signals from sensors. When voltage is out of an acceptable range on a given sensor for a certain amount of time, an CEL is given (or worse, it depends on the sensor).

By wiring in a resistor to give the ECU a different voltage reading, or by mounting the o2 sensor out of the stream of exhaust you change the voltage sent to the ECU. If the "new" signal is within accepted limits, a CEL is never thrown. These limits don't change, and the ECU does no "learning" for the rear o2 sensor.

If you don't throw a CEL in the first couple days, or couple hundred miles, you will probably never see one for cat ineffiecicy. These types of CELS are not thrown right away because cats are less effective when cold, and the ECU is programmed to account for that. Again, no "learning" involved.

good explanation but i never said the wiring method was bad. just the fouler

The foulers do the same thing but mechanically. You are reducing the amount of exhaust gasses the sensor is exposed to, and skewing the reading. Some cars need 2 of them to keep from throwing CELs, one drilled for the sensor, and one undrilled.

if im not mistaken this is almost exactly like the piece that the wayne guy makes, the guy whose email i listed earlier

if you have no problems GREAT but ive seen some on here who drove for 2 weeks with nothing and then BLAM...........

however, i am wondering what you mean by BLAM something other than the cel go wrong?

NO it just happens all of a sudden......

You probably wont get a CEL , but if your state has a sniffer test, it will not pass without cats.
