I'm looking at the AEM uego wide band O2 gauge and the Innovate DB wideband O2 gauge, does anyone have an opinion on these two or maybe even a better one?

I know the Innovate one comes with tuning software, but is that software garbage?

 

I've used both in various cars. IMO, the UEGO is best - easiest to hook up and with the SpoolinUp adapter, easiest to log with EVOScan also.

 

I have the innovate lc1 / db gauge no complaints

 

I got the AEM. It's pretty nice. The setup in EvoScan pisses some people off but all in all I can't complain.

 

The AEM is super simple to log through the factory ECU although it requires cutting a wire. Setup is also easy. No extra cables or other nonsense to deal with.

 

I have used both and so far I like the AEM better. If you want a better looking gauge go with the AEM and if you don't want to have to re-calibrate the sensor every once in a while go with the AEM. I can't say one is more accurate than the other because I got similar readings between the two.

 

AEM since long time, cba with recalibration to diminish 0.05 AFR ratio difference. For instance 11.50 or 11.55 isnt that different at all, so i think calibration story is kinda -maybe not a gimmick- but a selling trick so far.

 

Thanks for all of the helpful comments

 

What about the Stack Wideband? It's like 300 bucks, but has anyone used one before? I'm looking to get one to complete my stack gauge setup. I had an AEM UEGO before and i don't have anything bad to say about it at all. Great gauge and it did it's job just fine. This time around I'm going all Stack though.
