Review on 🔍 Analyzing Engine Performance: The AEM (30-4110) UEGO Air/Fuel Ratio Gauge by Aaron Jensen

Mounted on a LS Silverado (6.0) Swap. Installed correctly and although the readings were accurate for about a couple of weeks it started to fail. It fluctuates constantly across the rich to lean spectrum. During a vigorous drive, a fuse blew and stopped working. According to the attached documentation, it was properly merged. I will most likely return it or just buy another brand. This product is too expensive to "breathe" so early. Very disappointed with the quality and accuracy. This was my first experience with AEM sensors and most likely my last. The exhaust has been checked for leaks and the fuel trim has been checked to ensure it is not a vehicle issue.
