AEM wideband instead of stock O2?

RTFM.
Specifically, pages 9 thru 11 of it: http://aempower.com/images/products...s%2030-4100.pdf
The AEM has one analog output which can be configured in one of several modes. The default is 0-5v wideband, however mode P4 is a 0-1v narrowband simulation, including the knee at 14.7:1.

The manual is all greek to me.
So are you saying if I turn the switch to P4 I can replace the stock O2?
I can have the wideband reading from the gauge and send a narrowband reading to the ECU? And Paul is wrong?

Sorry. I think in terms of MS. I know the AEM only has one output so if it's being fed to MS you can't feed a simulated narrowband signal to the stock ECU(in the case of parallel install). Now that being said, please do some research as to whether the simulated NB output is accurate enough to be used safely with the stock ECU.
EDIT: Also something to consider. I see nothing about your car in signature or post so I have no idea what you run but be careful mounting the WBO2 too close to the exhaust ports. I think the stock 1.6 manifold o2 bung is a lil closer than recommended. I know the location of the o2 bung on an MSM is too close.

It seems to me that the resolution of a wideband from 14:1 to 15:1 isn't nearly as good as a narrowband in that range. But yes, you could use it to keep your car from throwing a code, though expect driveability to be affected. I'm doing that right now because the Bosch narrowband sensor I bought is defective (and I can't find the wrench to remove it), and I get little surges of power when cruising on the freeway, since the ECU keeps seeing the sensor convulsing wildly between rich and lean like a crackhead.
