Quick aem wideband question.

Ok so should i keep my stock o2 or can i toss it out and use the white wire to pin 4 on ecu to simulate the signal, i keep reading posts from others sayin doin it for link/logging and others sayin you need a buffer and some say they dont have a buffer they just wired it up. WTF is a buffer is that something i can make or get from radio shack.

ive read through about 15 threads on talk and here and im just so confused.

I'd keep your stock o2 for now anyway, the stock location is to close to the turbo anyway (people will disagree with this, but I personally prefer to follow manufacturers instructions, so it needs to be 36" from the manifold) then, if you decide to get link later you can just wire it in, and put an o2 bung plug in. or just a bolt.

The further away the WB is from the stock front o2 sensor, there will be more of a delay in the WB reading.

I'd put it in the front and run the sim. You can fab up a heat-sink like someone on the Link forums did, or just run it as it sits.

AEM is a crapshoot in terms of voltage, though. Mine has never read properly in Link, despite multiple configuration attempts.

I would (and do) run the stock o2 sensor in the stock location and the AEM sensor on the downpipe, just before the flex section. That is the recommended way (per AEM) and while you could get away with using it the other way, I wouldn't.
