where should i install my wideband? should i put it in the existing o2 hole? and if so what do i do with the other o2 sensor so it doesnt make any codes... or should i drill a new hole and have a new bung welded on the header and just have two o2 sensors next to each other

Have a new bung welded on. Best place would probably be where your V6 sensor was, just in front of the cat. That's where mine's going when I get the car back together and acquire a wide-band controller.

i have no cat does that matter?

It needs to stay hot. Generally it's recommended to have the Wideband O2 in the collector, at either a 3 o'clock or 9 o'clock position, so it doesn't get moisture accumulation as much and can stay hot enough to work and not burn out the sensor.

Mine is in my collector on my shorty header. Have a new bung welded in.

My current o2 sensor is in my header collector, so couldn't I just put the wideband there and relocate the stock one?

There is definatly no room on the passenger side collector so I guess both the stock and wideband are gonna have to go in the driver header

I'd put it in the factory location and hook up the narrow band wire to the ecm.

Otherwise the instructions say exactly where to mount it.

I think Paul's saying the same sensor will work as both wide and narrow band. You just need to hook the correct wire to the ecm. That way you only need to screw the wide band into the original hole that is allready there.. and leave it.

Yep, widebands have a narrowband emulation output usually. Then you only need the one sensor.

Ohhhh okay that makes total sense now

But in that case one entire bank could be running lean and you never know it. Would it be bad to put it at the Y-pipe collector even if it were a heated WB02?

All WB are heated as far as I've seen.

It needs to be close enough to get a non lagged response. I think AEM's instructions say like 36" from the outlet.

Boosh!

ok so got the wideband and it all looks pretty self explanitory. except 2 wires. there is 4 wires coming out of the guage and they are black red white and blue

red-12v
black-ground
white-5v output
blue- serial output

it says white and blue are optional, but which wire goes to the narrowband wire?

Dewey316 · Posted: Wed Apr 06, 2011 3:40 pm Post subject:

narrow-band would be a 1v output. Does the AEM do narrow-band conversion? I thought that the basic sensor/gauge combination didn't.

Dewey316 · Posted: Wed Apr 06, 2011 3:42 pm Post subject:

Just thinking...maybe the output is a up-to-5v output, and in the software you can configure it to be a curved 0-1v output?!? Check your documentation on configuring narrow-band output.

91camaro_rs · Posted: Wed Apr 06, 2011 9:12 pm Post subject:

yeah it says that the white wire is a 0-5v output, so narrowband would connect to the white wire then? and just leave blue wire disconnected

Ok I just read the directions (which are horrible) and it said use the white wire for any input of zero to five volts so technically if the narrowband is 1v then it should work fine right. Wouldn't the o2 sensor be sending the 1v to the guage and the guage just sending it to the ecm?
