why do you need two?

 

i read or heard somewhere that adding one or two to the existing would stop the cel, but it didn't.

 

did you drill out the hole before installing this?

 

There is nothing to drill out a bung is what your 02 sensor screws into, i welded 2 on top of the existing to back the sensor out of the pipe

 

than thats your problem.. if you used a spark pluf de-fouler, not only does it pull the o2 out of the direct stream, it limts the amount of air in it... except in our case it needs to be drilled out some.. worked so far for 2 people here

 

still working great for me at 500+ mi

 

same for me700+ miles...and i was pm'd to make one for $15...ill do it and if any one else want one let me know.

 

where you located?

 

Im currently using one thats MEANT for this purpose (off road use) and...
so far.................

... its not working, lol.

The peice is about the size of 2 of those HELP ones and the hole is about four tenths of an inch or so.... cant remmeber.

im trying to find a pic of it so i can post it....
not sure if I would need something longer, shorter, bigger hole, or smaller.i got the Turboxs exhaust, no cat, greddy turbo about 15k on the rebuilt motor, about 50k total i think...

 

Wait, I think I remember it working for me for about 970 miles before the CEL came on.

 

you know, its been so long that ive had it on the car that i dont remember the actual size...

this looks a lot like it, but i remember it being longer... cant remember, let me go to my garage and look real quick...

 

yeah, mine are twice that long

 

I ran this technique on my KA24DE-T S14 for some time with no problems. 1 HELP bung with THREADED nut welded to it. I was running emanage blue with OBD1 Engine Management, not OBD2. I had heard it is possible if too much exhaust gas is reaching the O2 Sensor some wire mesh can be installed inside the bung before installing the O2 Sensor. If you are creative this is feasable, dont know about steel wool but I think it would evaporate, LOL.

 

I am now at 1200mi. still no cel.
w00t

 

still no cel

 

miles?

 

I losts track but over 1700 now.

 

I'm suprised more members haven't tried this mod. Don't have a midpipe on my 8 yet but I have used this mod on Hondas since 1999.

 

The Honda PCM and the Mazda PCM are two very different beasts.

 

I know...never had to tap the brake 20 times then turn the wheel to reset the e-shaft in a civic.

 

and you dont have to turn the wheel to do that to a rx8..

beers

 

Your civic has an e-shaft?

 

the point is.
this cost 10$.
if it doesnt work for you, oh well, your out 3 gallons of gas.
if it does.
great.

 

lolwtfbbq?

 

yeah im well over 2000 miles now and im good......ive had 2 orders for me to make these at $15 each so if anyone else would like one let me know.
