Review on 🔍 LSU 4.9 Lambda WideBand O2 Oxygen Sensor for AEM 30-4110 30-0300 30-0310 - X Series AFR Inline Controller UEGO A/F Ratio Wideband 02 Gauge - Replace# 17025, 0258017025 by Ken Desens

I recently welded an AEM obd2 broadband to my CTS V-Sport and a connector at my local muffler shop to make sure the guy knows how to install it at over 10 degrees from horizontal, approx 15 degrees figured out. If you don't install it this way your sensor will quickly fail as it cannot dissipate moisture. If you install it on top of the exhaust pipe it won't either, it will get hot there and fail as well. I ordered this because I was thinking about it after installing it in my CTS V-Sport. I knew my '67 Camaro Classic AEM AFR gauges, the guy didn't install the plug properly because I didn't know the ins and outs of the installation, so I looked under my '67 Camaro, thought about it and wow, he set it to about 5 degrees below horizontal and this sensor failed about 100 miles after it was fitted to my Camaro that runs on a gas pump and just keeps the same number on the sensor. From start to finish this sensor and sensor was replaced by the S10 that I have Bought with the SBC to my 67 Camaro when I started it about 5 years ago. This sensor from S10 was on E85 when I first bought it and I switched it back to direct throttle because at the time I got this S10 we don't have E85 where I live (now we have ). My CTS V-Sport is also tuned to E47, 50% octane 91 and 50% E85. Some people who say the sensors don't work with the E85 are wrong. So make sure, especially if your sensor fails frequently, that your sensor is installed in the correct position, which may be causing your problem. The AEM OBD2 Wideband installation instructions really detail where and why you need to install it. Hope that helps. Stay safe there.
