AEM Oxygen Editorial Review

The AEM 30-0310 X-Series Inline Wideband UEGO AFR Sensor Controller is a high-quality controller that is accurate and reliable. It comes with a Bosch LSU 4.9 sensor and has outputs for a gauge on the canbus or analog. This controller can be run without a gauge as the controller since it has a 0-5 output for the ECU/flashpro. The calibration process is simple, and the readings are accurate. However, there have been mixed reviews about this controller, with some customers reporting issues with the readings being off, causing problems with tuning.
