A black bezel and black dual-faced faceplate for air\/fuel and Lambda are included, and an optional silver bezel with white dual-faced air\/fuel and Lambda faceplate is available (PN 30-0300-ACC, sold separately). An Auto Dimming feature is included. Locking connectors ensure a positive connection between the harnesses and gauge and a new single board design adds to the new gauge's durability.\nX-Series Wideband UEGO AFR Sensor Controller Gauge Accessory Kit, Includes Silver Bezel and White AFR-Lambda Faceplate\n\u003cul\u003e\n  \u003cli\u003eX-Series Wideband UEGO AFR Controller Gauge were fastest responding wideband air\/fuel ratio controllers in an independent test vs. 17 competitors wideband AFR controllers\u003c\/li\u003e\n  \u003cli\u003e0-5V \u0026amp; RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders\u003c\/li\u003e\n  \u003cli\u003eFactory calibrated resistor does not require free-air calibration, but technology allows for free-air calibration as sensor ages if user desires\u003c\/li\u003e\n  \u003cli\u003eUser configurable display via buttons on the gauge face for changing AFR values, Lambda and O2%, and 3- or 4-digit display\u003c\/li\u003e\n  \u003cli\u003eCompatible with vehicle\/system voltages up to 16V\u003c\/li\u003e\n  \u003cli\u003e52mm gauge diameter and slim 0.825\" gauge depth\u003c\/li\u003e\n  \u003cli\u003eIncludes Bosch 4.9LSU wideband UEGO sensor\u003c\/li\u003e\n  \u003cli\u003eCan display AFR values in hundredths of %\u003c\/li\u003e\n  \u003cli\u003ePatented X-Digital wideband technology\u003c\/li\u003e\n  \u003cli\u003eSilver bezel\/white gauge option\u003c\/li\u003e\n  \u003cli\u003eGauge cup depth only .200\" deep\u003c\/li\u003e\n  \u003cli\u003eAuto dimming feature\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe AEM X-Series Wideband UEGO AFR Sensor Controller Gauge Accessory Kit adds a customizable display and advanced monitoring capability to compatible AEM X-Series wideband systems. Part number 30-0300-ACC includes a silver bezel and white dual-faced air\/fuel ratio and Lambda faceplate, providing an alternate appearance for the X-Series controller gauge. A black bezel and black dual-faced faceplate are also included with the gauge system, while the optional silver bezel and white faceplate configuration is available as this accessory kit.\u003c\/p\u003e\u003cp\u003eDesigned for accurate, responsive engine monitoring, the X-Series gauge uses AEM’s patented X-Digital wideband technology and includes a Bosch 4.9 LSU wideband UEGO sensor. The factory-calibrated resistor eliminates the need for routine free-air calibration, while user-selectable calibration remains available as the sensor ages. Buttons on the gauge face allow adjustment of fuel-specific AFR values, Lambda, oxygen percentage, three- or four-digit center display modes, and CAN message ID settings when multiple X-Series Inline Controllers or Controller Gauges are linked.\u003c\/p\u003e\u003cp\u003eThe gauge supports 0–5V and RS232 outputs for data logging and feedback control, along with AEMnet CANbus connectivity for data logging and daisy-chaining multiple controllers across systems supporting up to 16 cylinders. Locking connectors help maintain secure harness connections, and the single-board design improves durability. Auto-dimming adjusts display brightness for changing ambient light conditions. The compact 52mm gauge format and shallow installation profile suit a wide range of custom vehicle interiors and motorsport applications.
