performance ecu & headers info (jltibbs, maxhopper, nismonkey)

What we did with Fezzik's 2k2 is extend the O2 harness wiring and have 2 bungs installed after the Cat.

You will need to install a O2 simulator to get rid of the codes

You will need a dual-output simulator. You will "tap in" at the engine-side connections (green and blue connections in front of the motor).

since my maxima is a fed. spec, do i also need an o2 sim? im not familiar at all with these types of things so any help would be appreciated. i understand his max was a cali spec but i know the fed specs are different for emissions. when i install, will i have the same problems with the o2 sensors and the CEL??? if so, i will need to get one of those simulators???

I wouldn't think you would have the same problems I have, since you only have two, and you have two O2 sensor ports on your Y-pipe.

This is what I have hooked up, should it be the other two???

[Dragon_ryder]

I went back to the shop today to pick up my old stuff. And I let my guy get the engine codes for me. I got

P0141 andP0155

i have no idea man, sorry. hopefully scott or somebody will know what they mean.

Both of those relate to "O2 Sensor heater Circuit malfunction"

The connections for the simulator to "tap into" are the two on the left.

Going forward, any members who use the '00-01 headers on a 2k2-2k3 Maxima should spend a couple bux to have two additional bungs added to the exhaust for the other two sensors. Makes life easier.

This may have been tried already but I just had the thought. I have an SE so I don't have to worry about the speed limiter... I know on the 240sx the automatic is not limited so if you use an Auto ECU in a 5spd 240sx it will not cut at the normal 118mph.. I wonder if it would be the same for the Maxima only instead of the Auto ECU swap for the SE ECU.

Probably too simple to work but I thought I would suggest just to see if anyone has tried it.

BTW, Headers and Y-Pipe look good.. I want some! I think my car already has an aftermarket Y-Pipe but the place where I got my exhaust redone welded EVERYTHING together so I can't take it off..

[nismo1219]

hey scott, just thought i would show you guys these pics. i was talking to you, mike, and jeremiah about some of the coming-up local shows i would be in at the last meet at the titan stadium. too bad i forgot the camara for the actual show, we were running late and rushed off without it. oh well, here are a few pics to show you how i did....

Good Job!

[Maverick7687]

Wow, I didn't see the pictures when I was in here last. Lookin' good! Can't wait to lower mine. I have 19's and the wheel gap is still atrotious (sp?) They also have 35 series tires too so that doesn't help any.

[nismo1219]

hey dragon ryder...about how long did it take for your header & y-pipe install?? im trying to figure out about how much an install would run me.

[Dragon_ryder]

lol, plan on waiting a while. it took my guy about 5 hours, hopefully it'll be different for you. The headers aren't easy to get to

[nismo1219]

werent they pretty much "bolt-on?" if so...you wouldnt happen to know of anywhere with a good how-to/DYI section would you?? im trying to get all my parts on before nopi and im running out of time fast!! AHHH!!

[maxhopper]

Yep, I helped install headers on a 3.5 - not a really fun job.

can you give me any advice or info that would make things easier for me when i attempt my install? im tired of waiting for my install guy and i REALLY want my headers and y-pipe on as soon as possible without having to pay out the azz for an install job. also, do you have any suggestions for installing my udp or sway bar???

Like scott said, header installs are a pain. If you're trying to get your stuff installed before NOPI, (I personally)I'd just install the Y-pipe and sway bar...those won't take nearly as long to get on your car.

[Dragon_ryder]

well yeah, the parts were bolt ons, the hard part was getting the stock bolts off, they've been on there for 6 years. Alot of wd-40 was used, it was kinda funny though hearing him speak in vietnamese and curse in english lol

If you have a Addco or Progress style RSB, you can use my writeup for it..http://www.moodym.com/maxima/tech/addcorsb.html

sweet! thanks man, i appreciate it. imy girlfriend had an amazing idea last night and i was dumbfounded that i hadnt thought about it before!! she said why not call "4 Way Muffler" (the guys who installed my exhaust) to see if they could install my headers and y-pipe...seeing as how THEY gave me the main idea for doing it in the 1st place!! GREAT idea!! maybe we can get it on monday!!!!

[nismo1219]

well i called up "four way" and they wanted me to bring the headers and stuff by for them to look at. so i did and they told me they could do the install. he also said he'd only charge me $35/hr for the job. so as of right now it looks like ill end up dropping it off thursday morning!!!!
