WideBand o2

**jbGST** · March 19th, 2007, 11:40 AM

Ok so Im thinking Im going to purchase a wideband o2 here soon. I was thinking about the PLX one (Any Suggestions?)

Also I know alot of them have a narrowband output and was thinking about replacing stock wideband w/ narrowband output from PLX wideband.

I remember hearing something about the wideband o2 sensor has to be a certain distance from the head (could burn it up) anyone know for sure what kind of results I would be looking at running it where the stock o2 goes??

Also any thoughts about using the narrowband output on a wideband for the ECU?

NB output from a wideband will not work.. Ill explain later.....

:P

i've got a zietronix and i haven't had problems. it also counts as a data logger if you wish to use it as such. it also has a narrowband output for your stock ecu.

Please explain.

ill tell u later..

no it absolutely will not work right.. ur ecu will not tune itself right..

anyone who says differently has no idea what they are doing..

(no offence turbocooker.. but think about ur own problems with leaning out and "cooking turbos")

i dont have time right now to splain :P

nevermind.. Ill take the time real quick using the most basic logic i can..

there is more than one kind of o2 sensor out there..

In fact even between the 1g and 2g the output voltage of the o2 sensor when the ecu is calibrated to decide the mix is correct is totally different..

The curve the sensor outputs is different betwen cars and sensors..

The Generic output from a wb will NOT be calibrated correctly for your car..
The ecu on a 1g thinks .82 volts or whatever is what is the "proper mixture"
that .82 volts may be something COMPLETELY different on a wb.. could be rich.. could be lean as fuck.. bottom line is if you ARENT using a stand alone to totally control your fuel enrichment map the ecu is going to fcuk with your mix untill it thinks its right.. and will even throw a code if it cant get it there..

so you will either be tuning totally against the max enrichment or the min enrichment on your fuel trims.. Always..
So... NO do NOT use the 1volt NB outlet from a wb sensor..

THe reason most people use this is they are too stupid, broke, or talentless to weld on a new Bung into their exhaust to mount the wb and would rather just screw it into the stock location which is totally WRONG and VERY BAD.

The WB o2 sensors CANNOT handle high egt's and the install instructions even STATE to install them at least 18 inches downstream from the head.. The stock location is half that distance away.. you will fry your WB sensor and not even know it.. itll just read more and more off untill it dies.. (Which wouldnt matter for the kinda person who would use them like this anyways.. They will never have a fast or reliable car.. They are the ones that hack the hell outta our cars due to lack of funds or brains..)

AND the stupid heatsinks are retarded.. why would you bother with a heatsynch when you could just weld a bung into your exhaust a little farther down.. and leave the factory NB intact for the ECU's sake..

So bottom line.. Its f-ing retarded to replace your NB with a WB and use the 1v output.. totally wrong on more levels than i can count..

Grow some balls and learn how to weld or take your downpipe to an exhaust shop and have them weld one on..

End of rant.

ok ok I totaly deserve that,, even if not directed directly at me,,, I was being a newb and just wanted to hear what i wanted to hear... Thanx for wasting your time... but I can tell you I have been reading like hell on this subject since my last post and you are right,,, except a little off on the distance from the turbo from what everyone else seems to be saying.

Additionally, Hopefully I have the right concept here rich should = high hc's lean should = lower hc's.. a wideband will be something I will need in the future n e wayz... so I was thinking I can steal your maf,, hook up the wideband, advance timing during idle (from bens house of custom eeproms), increase idle speed up to around 820 (hopefully will stay under 1k for smog) and lastly lean the shit out of the fuel as much as safely possible long enough to limp the bitch over to the smog shop and hopefully pass...

Okay Okay according to you I just need to replace my MAF,,, I say just incase your wrong, lets try wb too!! need it n e ways :) why pay 30 for pre test when can pay 300 for wb o2. o yah! that means your exhaust is getting a bung welded on!!!! we can take it to a shop for that I will get a bung plug 4 u too (do you already have bung plugs ben?) and dont bitch bcuz your high ass hc's are burning a hole in whatever is left of my cat!!! Oh and all this becuz now Im dead set on a MAP w/ EMS setup Fk a MAF! But i am going to need to buy a 2g maf for now till I get other stuff ironed out so I can make the car drivable w/ the e3 16g. So I really really really do not want to buy a 1g maf.

this is all asuming my concept of high hc are a result of rich conditions, which from what i have read look to be tru!

none taken. that turbo problem had nothing to do with leaning out. the timing was wayy retarded and was sending hot gases to the turbo. the turbo wasn't really damaged, it got the oil ring too hot and caused it to start leaking. things like that happen when your working with new software, and the guy who was helping me get the timing sync'ed claimed to have use the ems before. its all good now though. also i never told jbjst to use the NB output, i was stating what the zeitronix comes with. i dont have the problem with the NB because im not using it. i've calibrated my EMS to the voltage outputs of the WB supplied by zeitronix.

This wasnt from reading recently jason and wasnt directed at you at ALL :P

Ive had this debate OVER AND OVER with retards on various forums im just sick of it...

Its almost always because the kid cant weld or doesnt know someone who can (Which doesnt apply to you of course..)
And was too cheap to have someone weld on a bung.. And that was always the only reasoning..

This is OLD OLD news.. And from foggy memory so im sorry if I was off on the 18 inches but im pretty sure thats what the install guide says for some brand or another

And you were STUPID close to passing smog..

We couuld probbaly just pump 100 octane in that bitch and smog it again..
