AEM Wideband emulating the stock sensor and placement

[CompuBob_TSi]

I just purchased a AEM Uego Guage type wideband and I am being told that I can use it in the same place as my stock sensor and use the 0-5v output on P4 setting to emulate my stock sensor so I don't have to keep the cars origional..

also, I have been doing some reading up on this and even though everywhere on this forum it says to mount it 35" away from the exhaust, my instruction manual says 18 inches. so I assume those are old posts and they have started using a better sensor since then.
But only problem with that is I disconnect my exhaust when I run at the track, so I don't want it on my downpipe.
My friend has been running his wideband in the stock location for years without a problem and he swears that I can do it too. maybe my near stock car will not generate enough heat to damage it.
also I have a tubular O2 housing with external dump, but I don't think that matters since it's basically in the same place

Stock 02 sensors output 0-1 volts. My wideband is right after the first bend in the down pipe. Works just fine and you can still have it mounted when you run at the track. You even take your down pipe off at the track? I don't really see the need for that. An open 2.5" downpipe will flow enough for serious power.

You even take your down pipe off at the track? I don't really see the need for that. An open 3" downpipe will flow enough for serious power.

I just read the manual again and P4 setting emulates a non-linear Nernst Cell Calibration (0-1) volts. so does this mean that the stock ecu will interperit it?

and I have a 2.5" Straight turboback exhaust with a tubular O2 housing and external dump (it's FWD so there are some extra bends), and I go from 14.5 to 13.8 just by removing the exhaust, crazy I know.. you think it would flow.. and it's mandrel bent, so no crushed bends.

Yes the 0-1v signal can be interpreted by the stock ECU. As for taking the exhaust off, i agree with the other poster, just take it off from the cat back. I'm sure the DP (unless stock or a tiny junker) will provide all the flow you need to still run 13's.

I ran 13.8's on the stock DP, stock cat in place, 3'' thermal cat-back, K&N FIPK and the boost turned up on the stock T-25 to spike 18 then fall off to the 12 (all it could hold) by redline..shifted at 6200-6500 RPM.

There's no reason that you should ever have to pull the DP off. I'm surprised you haven't melted anything running that way.
