Wideband O2 sensor question

[jackalopeTsi]

if i buy a wideband o2 sensor, like this one can i replace my stock o2 sensor with the wideband, or do i still need a narrowband in the stock location?

It has two outputs..

1. zero to one volt... Which is a narrow band output voltage range... Use to replace std o2 signal
2. zero to five volts.. A normal wide band voltage output... Use to tune wot AFR based on 02 volts. You can drive a gauge with it but you seemed tight on $ so do that later.

Here is the manual in .PDF

so if i do this, on my logger will i see a accurate wideband signal or will it be an inaccurate signal that im seeing now?

The 0-1 volt is a simulated narrow band output....

Meaning it is intended to make the ECU think it has the stock 02 sensor.

Dont go by that signal as a tuning guide.. Use the 0-5v..

If you have a datalogger with a 0-5v input on it use that..

I dont know which datalogger you have..

i have mmcd on my palm with a home made cable,
wouldnt the simulated narrowband signal be the equivalent of the wideband signal though, like would it be an accurate reading translated into the narrowband signal so the ecu could read it?

The 0-1v has 1/5th the resolution of the 0-5v signal... its like reading a clock w/o a second hand vs one that has one...

You will get a more accurate 0-1v signal from the lc-1 than a std o2.....

You can plug the 0-5v right into a laptop and datalog using the included connector and logworks software. Part 6.3 of the manual I gave a link to. They also have online help and a forum.. http://www.innovatemotorsports.com/forums/index.php?

Since you wanted to save $ I suggested just getting close using a DVOM for now.. You will still be 100x closer than any seat of the pants non WB tune..... If you can borrow a laptop you are golden..

i got a laptop for a graduation gift from my parents for college, but it doesnt have a serial port. and what is a DVOM?
i think my o2 sensor is going bad, and just looking for an upgraded replacement, i could get it and get a gauge later, my egt sux anyways, good replacement down the road.

DVOM digital volt ohm meter...

A analog volt meter is probably better for an o2 signal but nobody really uses them anymore...

What ports does the laptop have... there are serial port converters....

Strike that...... innovative.. The guys who make the LC-1 have a USB to DB9 connector for it they sell... $30 just get that and its a done deal..

I like the LC-1 alot better than the AEM i was running. you cant datalog a AEM or the gauge style AEM w/o AEM EMS...

The LC-1 is alot better all around system and a nice price..

on the website it says it works with obd 2 ecus, i have a 1g and am obd1, how would i set this up, and also a video on their site said 6 inches from the turbo is not good, stock location is what, 3-4 inches.

It works with OBI.. A 0-1v o2 signal is a 0-1v o2 signal... II or I in regards to OBD makes no difference. Just as swaping good front o2 sensors between a 1g and a 2g wont hurt anything.

Alot of the sales info is worded for the most popular newer cars.... EV0, WRX even 2g DSMs are'nt everybodys main target market anymore..

The stock bung location is fine... MANY DSM owners and tuning shops have been putting wideband sensors in that location with no problems.. The sensor element is no different than any other sensor on the market... Dont worry..

Maybe make the copper heat sink like in the manual... I had some copper so I did what the manual suggested... Many people do just bolt in a wb02 sensor in the stock bung and it works just fine.

Because the gas composition does not change in the exhaust system it does not matter where you put it. As far downstream as possible is best for heat reasons. It should be before the cat, because the cat changes the gas composition. It should also be at least 1 ft from the tailpipe (if no cat is installed) because reversion effects can draw in outside air into the exhaust from the tailpipe.

thanks for all your help, i think im gonna try to get this, i need a new o2 sensor anyways

Push come to shove go to a u-pull it parts yard and get a O2 with 4 wires cheap as dirt.... then save the money for this...
