can top o2 sensor be replace with wideband o2?

[tweety2300]

Thanks. That what I was saying earlier.

Also, the wideband should be placed after the turbo (which is why you want an extra bung on your DP). Wideband cannot replace your factory narrowband sensor because it doesn't connect directly to the ECU.

Did you read any of this? The aem widebands have a wire for narrow band reading to connect to the ecu and a logging wire to connect to aftermarket ecu or piggy back

True. But, your wideband does not "replace" your stock o2 sensor and the stock o2 sensor must stay in place (if you're just adding a wideband), right?

Also wondering the same question. Because any wideband will be after the turbo, not sure if that distorts factory settings like fuel consumption or other things.

The wire is for if you are replacing the stock o2 sensor, im not saying it should be done. The way it should be done is weld a bung it 18" or more from the motor. Or replace the downstream o2 sensor with it and deal with the cel for it or use a resister

Isee. I think i'll just replace the upstream one from autozone , wat the heckk lol. Problem solved. Good to know these information tho, really appreciate it.

just to touch on the wideband thing one more time...the factory computer is what cares...ideally any car 'should' run a wideband primary o2 sensor, as it allows something known as 'high load closed loop'...in which it can remain very accurate in closed loop conditions where a normal band sensor can't (and therefor switches to open loop and drops the o2 sensor entirely)...

So the only way to get a wideband to work with the stock ecu...is to make sure it has the options tweety talked about...some have a narrow band output/wiring specifically for this...narrow band to the factory ecu...wide band to your gauge, data logger, etc. for tuning...you can't throw a wide band signal to the ecu...it'll start seeing numbers outside of the voltage threshold, and won't know what to do with them...and you'll just get all kinds of low speed driveability/idle problems...with a number of codes...

you CAN have a wideband o2 sensor in place of the stock primary sensor...it just HAS to have a narrow band signal output to work with the stock ecu, thats all...its usually just easier and cheaper to run 2 normal o2 sensors, and have a 3rd bung welded in somewhere for the wideband, and never bother trying to feed it to the stock computer...

Also forgot about making sure the voltage sent on the narrowband signal is the same as what the ecu is supposed to see, protege should be fine but you get the occasional oddball car like my 323 that uses way higher voltage

very good point and I have to agree with ya

just out of curiosity which wire is for datalogging on the aem uego? and which wire on the ssafc does it go to? i know ive read it somewhere but couldnt find the answer for the life of me lol
