+1. Do your homework when buying a car bro, especially if you have plans to mod it.

 

I got nothing, here

but I did go on G35driver.com and find all your posts. lol!

 

found the help method on another forum. This work and you don't have to splice any wires...cheap too...only $5 for each pack and you need to packs.

yeah I meant the non foulers

you don't actually use them as they were originally intended with spark plugs

the alternative involves soldering some wires - note the nissan engineer said the same thing. This method can be undone easily and doesn't require soldering.

ONLY DO THIS IF YOU EITHER HAVE TEST PIPES OR TONS MORE AIR FLOW THAN STOCK - TO THE POINT WHERE YOUR CAR TRIPS SES OR CEL LIGHTS

otherwise who knows how the car will react. It might start running really rich - which could be good or bad depending on where you live and what gas you run. It's up to you at your own risk to try it

here's a compilation of all sorts of quotes I've saved about them from users from all sorts of websites.

they are called spark plug anti-foulers. i have them on my msp w/ corksport exhaust. use the 18mm ones and just drill out the bottom of one of them with a 1/2" drill bit (do not cut it off) and screw them into each other. it creates a chamber outside the main exhaust fow for the o2 to get a proper reading. suby guys have been doing this for a while with no cel/mil.


The heat will make the O2 active, but since it's out of the more laminar flow, that means less poloutants get to the O2 sensor, and thusly, it thinks the air is catalyzed.


i just went and got the HELP! Spark plug non fouler. Part 42002 for 3.99 from autozone.
Its a 2 pack, that you screw together, and then screw the open end into the o2, and the other into the bung.
This does require that you drill out the hole to allow for more flow to the o2, but thats pretty easy.


We datalogged the effects and it keeps it at the voltage where it thinks theres a cat there.


Never thrown a cel with this fix, proving once again it works

 

Yeah they might as well get rid of the search button on this site......it sucks ****!

 

Thanks guys now I have something to do while I wait on my Kinetix VSS

 

So essentially this is a proven method to trick the ECU, which should result in a power increase for the modded peoples?

 

it's a proven method to make the ECU think the pollution/emissions are within spec because it won't throw a code and thus reducing power

however, if the MAF is saturated or beyond it's intended range, the ECU won't know to add even more fuel. It can only add so much fuel. It won't add more fuel than it was programmed to add.



does anyone know if you can run the APEXI and Emanage at the same time?

the APEXI alters the MAF voltage, the emanage adjusts the injectors

It might be that you need to be able to do both to REALLY control the ECU... or get a standalone EMS

 

Maybe your Z when you get...I went .2 faster stock in the 1/4 than that magazine did in that 300. Stop magazine racing, race one on the street and you'll see they arent all they are cracked up to be, so much Hemi hype. Most mags run low to mid 14's in them anyway. Plus who cares how much power and tq it makes, ever heard of a power to weight ratio?? They are heavy! Thats how cars like the Lotus Elise can run low 13's in the 1/4 with only 190 hp

 

another good find Sentry 65 love ur website bro .saved it to my favorite it just needs your input on different mods that would be great.

dont have any cell lights but im doing this mod anyway ill post on here my findings probably next week,,,

thanks

 

I gotta agree with that. I can understand them wanting to closely guard how the computer controls the engine but it sure makes it difficult for anyone wanting to do significant mods.

 

thank you....suddenly i dont feel alone anymore

 

hehe my website? you mean my webspace?

 

HAHAHA LOL thats classic



one question how did you completely turn off the VDC

thanks

 

you pull the black fuse behind the shifter under the center console

 

I'm starting a new thread about the ECU

https://my350z.com/forum/showthread....36#post1434136

 

is there a reason as to why i havent tripped the CEL with my xerd test pipes and injen CAI? is it more likely to happen when i get an exhuast or y-pipe?

 

so far it seems that people with ONLY test pipes and intake or even plenum too, don't seem to trip SES lights

if you added exhaust, headers or cams, possibly so yeah

you can probably dig up threads on it here. I've read them so I know they're on this site

 

Ive had an intake, plenum, exhaust and test-pipes on and off the car a few times, but a total of about 20K miles at least and I have never tripped the CEL with them. I know a kid who's CEL came on 1 week after he did it, and hes on factory exhaust.

 

I'm sorry, but it just pains me to read this. I see lots of people that know a lot making this same mistake. It's not backpressure that makes torque. Ever. The thing that makes torque is length and amount of flame wave front propogation. A long piston stroke or advanced ignition timing or simply increasing displacement works. Additionally, volumetric efficiency increases cylinder filling- making the most out of your cubes.

What cams and test pipes and all these other things do is possibly decrease velocity of the intake charge or exhaust pulses. As a result, they increase total flow at higher RPM, but the loss of velocity decreases efficiency and therefore torque.

So, notice no discussion of backpressure. It doesn't matter here. In fact, less backpressure can even make more power. Ok, I feel better now.
