I bought my car about two years ago. One of things included was a new AEM wideband gauge and sensor (aka UEGO). The kit was literally spankin' new, but had been removed from the packaging and stuffed into a small box. It was one of the first things installed when I got the car running for the first time a few months later. The gauge was powered from the kick-panel fuse box using a 10 amp pigtail fuse. It was grounded straight to the chassis with a spade connector. The sensor was installed into a bung I welded into the dowpipe right after the flex section.
Right from the beginning I had problems with the gauge logging correctly in DSMLink (which is a very common problem). After tinkering with all the different AEM inputs, the closest I could get it was within .1 between the gauge and Link. About a year later the gauge suddenly began reading differently and I had to mess with Link again to get it to work. This time even more innacurate than before (within .2).
Fast forward to a few weeks ago. While driving down the road the gauge suddenly went black. I figured the fuse might have blown or something like that. After inspecting the wiring and finding no issues, I pulled the gauge and hooked it straight to a power source. No change. Testing with a voltmeter shows zero continuity between power and ground pins on the gauge. So the conclusion is the gauge simply broke. So I decide to try and call AEM. Apparently the warranty period for AEM electronics is 12 months. Even if I had the original purchase receipt, they won't replace or repair the gauge. After only 2 years and 5k miles, the product is considered well past it expected lifespan and the failure is not a surprise to its manufacturer.
Thanks to AEM's poor manufacturing and even worse warranty policy, I'm now out $200 for a new wideband. Will I buy another AEM? Absolutely not.
