man thats awesome, i have an 07 and i have my CEL on and i want it off. im going to do the same thing you did. thats good stuff lol

 

yeah dude, 1500 miles broken in yesterday. I went to willow springs to a drift event and back home. NO CEL. just weld the hole shut on the first Sparkplug Fouler, and Drill a 1/8" Hole there and Stuff 00 Brillo Padding from homedepot. and you should be good. ever since i had my car i never had all the warning lights turned off lol. it feels so nice to drive on testpipes without a CEL. and people think my car is stock haha I'll post some pictures later.

 

yeah man pictures would be awesome

 

good job man, yea pics would be great, and you say it helped your gas milage? what about performance wise?

 

Have an 06 350z with turbo xs testpipe that have non fouler built in and i added two more tall one and drill one out and i been driving for like the whole day yesterday and the whole day today and still no checl engine

 

I tried the double stack method and CEL after 200 miles however jacked the car back up removed one of the non foulers (the bottom undrilled one) and just kept the drilled ones in and disconnected the battery and then reset the ecu through the ecu reset/idle relern proceedure 2k miles later still no ecu running rich though but just bought an accessport and going to lean that bad girl out.but in summation I was getting the CEL when I had them stacked but with just one no CEL

 

I run the TD Borla with custom resonated straight pipes, and intense power non resonated Test Pipes. I don't feel its a big deal about a light anyway if the car performs better and you don't plan to sell it? Its when smog check and selling it when its going to matter IMHO.

 

That is true and I got a good power increase without a tune and more throttle response after shitting especially from 2nd to 3rd gear I cant wait till I tune and I might be throwing NO in it but I dont know if you can retard the timing with a cobb accessport if so I will run a 50-75 shot

 

Why not uprev? Waaaaaay better for tuning..

 

i have a 2006 without defoulers and threw the P0420 and P0430, even reset ecu few times and still there, the car's running rich and sometimes it dips the rev's while idling, havent felt that increase of performance that you mention, so i dont think is only a "light" only

 

I used to have an ms3 tuned with Cobb ap, which you are indeed able to pull timing, so I assume with access tuner race ( atr) you should be able to do the same for a z.

 

Mine just popped up after 1150 miles and I'm on an 03. No non-foulers though, the guy at O'reilly's turned em off for me and I bought non foulers gonna try the padding trick when I put em on

 

and?

 

what padding trick?
