AEM UEGO or PLX SM-AFR?

Hi all,
I'm trying to decide whether to purchase an AEM uego wideband or the PLX SM-AFR for my b16 swapped civic. I've got the OEM narrowband o2 sensor in the header bung hole and I'll be placing the wideband in the test pipe bung hole. I understand that the AEM uego can only output 1 signal at a time but if I've got the OEM narrowband on as well as the wideband inline do I really care if the AEM doesn't output both signals at once?

My builder/tuner is recommending the AEM uego but I believe Hondata recommends the PLX devices. I've got an S300 by the way and can get the AEM uego for less than the PLX device + gauge.

Any help is greatly appreciated.

Thank You

I would stay away from the AEM and get the PLX as we only recommend that Wideband.

Can you give me reasons why we should stay away from the AEM? I would love to read the specifics as to why. If you've already explained why in another thread/post then a link to that would be great as well, I searched and only thing I could find was the 1 signal at a time statement.

Thank You

The AEM only has one output, which can be either wideband or narrowband. The PLX has two outputs, narrowband (to simulate the stock o2 sensor) and wideband (for lambda datalogging). Incidence of problems is 20:1 in favor of the PLX.
