Extra bung or only WBo2?
 

First off, I have a voodoo box, but will probably upgrade to a MS as soon as I have some funds.

For now I am trying to work with what I have, which is an AEM WBo2 and the voodoo box. From what I have read, the simulated NB signal sucks. So using the WBo2 NB signal for the stock ECU doesn't seem to be an option (unless anyone has had a different experience). So as far as I can tell, I can either put in the money for MS now (which I would REALLY rather not do) or get an extra bung for the WBo2 and keep the stock NB. I have am using a cat delete so the second o2 is already going to be simulated, can I just put the WBo2 there? I heard it is better to have it further in the exhaust anyways.

Any suggestions?

I am not aware of any problem with the narrowband output of the AEM, though of course you need to satisfy the stock ECUs requirement to sense heater current on both O2 channels.

Installing another bung pre-cat would be simplest from a wiring standpoint, as you can just plug in the stock O2 sensor and be free of worry.

Upon further inspection, the FM downpipe comes with an extra bung already for a WB. I will just be simulating the post-cat o2 with a cap. and resistor, and keep the stock NB for pre-cat.
