Description

The AEM X-Series Wideband UEGO AFR Sensor Controller Gauge (30-0334) from ZZPerformance is designed for precise air/fuel ratio monitoring, crucial for effective engine tuning. This gauge utilizes AEM's X-Digital technology for rapid and accurate readings, enabling users to optimize their engine's performance. It features a prominent 7-segment center display, 87% larger than previous iterations, with auto-dimming capabilities for optimal visibility. Key technical specifications include the use of a Bosch 4.9LSU wideband UEGO sensor and compatibility with vehicle system voltages up to 16V. The gauge offers 0-5V and RS232 outputs for data logging and feedback control, as well as AEMnet (CANbus) for data logging and daisy-chaining up to 16 cylinders. The display can show AFR values with hundredths of a percent accuracy. The gauge itself has a 52mm diameter and a slim 0.825-inch depth, with a gauge cup depth of only 0.200 inches. It comes with locking connectors. This gauge is specifically designed for 2008 and newer cars. It does not work on LSJ cars. The unit features an OBDII pass-through connector, allowing for logging through standard HPTuners without requiring a Pro add-on. It is validated to work with software such as DiabloSport inTune 3, Trinity 2, EFILive, and DashDaq.
