Default AEM UEGO Install/Review

I finally installed a wideband O2 sensor in my car late last week and figured I'd put up a quick review. I was debating between an Innovate LC-1, an Innovate MTX-L, and an AEM UEGO.

I was going between these three because I needed it to connect with RomRaider for datalogging, and these three can all do that. I decided to go with the AEM UEGO after reading a bunch online for three reasons: I read a bunch of complaints about Innovate reliability, I read a bunch of complaints about Innovate having garbage customer service, and finally, because I read a bunch of glowing reviews about's customer service. Yes, there are bad reviews and good reviews about pretty much everything, but there were a few too many bad ones about Innovate and plenty of good ones about AEM.

And I can verify that's customer service was great...I called and emailed a few times with questions as I was researching and then when I was installing, and they were super friendly and knowledgeable.

The install went smoothly, and the instructions were well written. I also followed these two videos that put out:

(Note: these videos have disappeared unfortunately... They aren't mine, and I don't have copies! Bummer.)

(The second video isn't for the same gauge I bought, but the video is still helpful in regard to wiring. You'll also notice they have a sweet coupon code showing at the bottom of that video!)

Here's where I put the sensor in the downpipe:

I wish it ended up a little further from what I think is an A/C line coming out of the firewall (which is my fault), but I think it'll be fine. As for wiring, I wired it into the clock for all power stuff, and the wiring is explained in the video.

Now that it's up and running, it works great! It responds crazy fast. The display also has a light sensor above the numeric display that allows the gauge to auto dim and brighten depending on how bright it is outside:

Anyhow...I highly recommend it.
