O2 sensor is garbage

Summit RacingSummit Racing Verified Purchase

AVM-30-0300
Had this gauge in my mustang with a 347 for a month and the sensor went out. I contacted aem and they don’t warranty the sensors, even after only a month. They just give you a bunch of talk about how there’s too many variables that effect o2 life, even though my car has 3 o2 sensors and theirs was the only one that went out. Car was tuned with quarterhorse and has perfect a/f ratios. Gauge works great, aem should step up and offer some kind of warranty for the sensor. Will never buy another aem product. ...read more

I had this meter in a old car that was stolen. Have a new car now bought the same gauge because I liked it. Works very well.

Nice kit

Nice addition to my dash, welded the bung in my x pipe so it's a little delayed but it's not aem problem. All of the optional wiring is nice as well now I can data log threw the oem computer using my ac psi switch. Good product in a nice package.

Owned two and both broke

Summit RacingSummit Racing Verified Purchase

AVM-30-0300
I have owned the non x-series UEGO and it lasted for 18 months. I replaced it with the x-series UEGO and it lasted 17 months. The non-x series lost 1 led in the display and then another led, a few weeks later. The x-series would start showing lean and every now and then, would work for a minute, before going back to full lean. I assume its the o2 sensor going bad. The UEGOs come with a 12-month warranty. The x-series unit I have a spare o2 sensor for. If I had to go over, I'd have to pass on AEM products. ...read more

Tune the right way!

Summit RacingSummit Racing Verified Purchase

AVM-30-0300
It works just as it should. I bought it to tune my carbureted truck. It provides fast accurate readings. The most difficult part of the install is installing the bung. I have been wanting an air fuel ratio gauge for a few years now. Now that I have it, I should have never doubted buying it sooner.
