Are you running the wideband in place of the stock o2 sensor, with the stock ecu? I dont think thats gonna work.

If it is in the stock location it will not read accurately. i put mine about 4 in front of the cat.

I'm running my AEM in the stock location with no OEM sensor hooked up. The AEM sensor will not work for the stock FC ecu. It is just temporary until I can get my car to a shop to weld the bung on further down the down pipe. Needed to see what the AFR was with my car that had street port and supposedly untuned safc.

I have a heat shield for mine because it is too close to the turbo in the stock location. It's also on a car that I barely drive (probably 5 miles a month) so I knew that it would be ok as a temporary thing.

If you drive this car regularly I would suggest doing it right the first time.

FAL I agree with you on the placement of the sensor. I put mine just in front of the RB presilencer. Lots of people have, however, run the Bosch sensor that is included with the AEM, in the oem location without issue.

But as a guy above you said, it sends a 0-5v signal... Thats not what the stock ecu wants to see.

Zietronix has a narrow band out put to feed the stock ECU. It's one wire tht plugs into the factory o2wire.
I thought AEM also had a narrow ban output?

My wide band threaded into my header no welding required. Plug the sensor into the AEM +power+ground and run narrow band wire from AEM to factory o2wire.

i have it the o2 welded before the preslincer. im running a apex neo and stock ecu. so i just hook up power and ground?

Yes that is all that is needed.

I take that back. The AEM, when set to P4, will send the correct emulated 0-1v signal. I figured it did, but it's been a good few years since I saw the manual.
