what year? m/t or auto? hw many miles?

 

05 6mt 23000 miles

 

got pics? I might try this when I put on the gutted cat..

 

ill put up pics when i put my pulleys on sat

 

photos?

beers

 

its on, so far 2 days no cel.
I drive the **** out of it. lol
I will keep this thread up dated after another week or so.

 

yeah im driving mine pretty hard too.

and here is a pic of the part to get

 

you are one of the lucky ones.

seems to work about 50 / 50.

beers

 

With one the cell comes on shortly after 312 miles.

Tested on two different manual '04's

2 it comes on in 30 - 50 miles.

 

still great after second fill up (so far 298mi)
on mine

 

yeah ive drove two tanks on mine so thats 400-500 miles. like i said maybe its the size you dill it out to fit the O2 sensor.....maybe 31/64th is the key...at least for me lol

 

this particular idea looks to be popular elsewhere too...

sheit, I would try it but my 8 is down. what was interesting when I replace my cat with one of rx7stores resonated jump offs I didn't get a cel for almost 600 miles....

now its a whole different story.

 

This works for every vehicle I have tried it on...I have ran it on my denali for years now. I tried it on my 04 AT with midpipe and it did not work at ALL...code would reappear within 50 miles. Tried it for months. I used one, I used 2, started with a small hole, then went bigger...nothing worked.

 

still great at 320 mi

 

320 miles with what driving style?

 

mixed, stop and go traffic, with a good amount of beating/ highway driving red lining.

 

same with me and i just ran an autocross race last sunday with 5 runs...still no CEL

 

How long until the CEL comes on is dependent of gasoline quality as well (how cleanly it burns) I was able to drive 400mi on 76 premium (with multiple redlines) before the light came on ~ my girlfriend borrowed the car and put in $15 of premium from arco ( ) and the light came on within 40 miles of regular driving. I noticed similar observations with a gutted cat as well...

 

The parameters to set a CEL are in the service manuals, has nothing to do with distance, time or gas quality.

It takes a certain number of 'drive cycles' to set a 'pending' code, each one a specific time of cruising, a certain time at 'fully warmed up' etc.

Then a specific number of these drive cycles are required to set the light to on. After another number of cycles the light will turn off, to make room for new codes, but the code is still set in memory.

The ECU can check the O2 sensor if it wants, sends a check of rich/lean pulses and looks for corresponding signal moves. This is why the electrical sims all fail to fool it.

well my car has had over 40 "drive cycles"
and been ran on 89 oct. and then filled up half (back to top) with 91, and then all 91.
STILL no cel, at 456 mi.
I am pretty confident this worked for me, but if it happens to come on I will post up.



I recomend coughing up the WHOLE 10$!!!! omg.
and try this mod, if it doesnt work, shux your out 2 packs of smokes.
if it does, you have no more cel.!!!

:cheers:

 

Are you guys running full blown midpipes, or just ineffective cats that were triggering the code because they went bad?

 

well im running the exotic speed exhaust with the midpipe

 

I have no cat what so ever, took it to a local shop and had a guy weld in a straight pipe with a bung in it.

 

Just to add to the list of things that don't get rid of the cel rear cat low, I added two o2 bungs to my cat less pipe and still have cell.
