I like it because it can fit where I currently have the narrowband A/F guage and does not take much room elsewhere.

 

I have It. As of now I have It boxed up and will be replaced with my narrow band A/F Ratio Guage. I like how It Is offered with an adjustable calabration output.

 

they are cool, but suposedly only read to 11.0 A/F and below that, go OL "offline"

 

I understand It reads below 11.0 A/F *when datalogging* - but does not not display this on the actual Guage.

 

That is correct. The gauge is limited to 11 to 17 I believe but the sensor reads a wide range which can be displayed or logged with your EMS or PC.

 

I have the older non-gauge type and it's been totally useless up to this point. Apparently it does not interface well with the datalogit, causing lots of noise and poviding a useless signal. I'm not the only one to experience this. I think if you use it with the AEM EMS you'll probably be ok, but if you're buying it for a PFC/datalogit, you may want to look elsewhere. Here's a thread I started on the AEM forum that basically went nowhere other than confirming that others have the same problem.......

There's also several others on the datalogit forum with my same woes...

Between the problems with the AEM CDI and the AEM UEGO, I think I'm fniished with AEM....
