AEM 30-0300 X-Series Wideband Gauge with AEM / FAE Wideband Sensor

X-Series Wideband UEGO AFR Controller Gauge were fastest responding wideband air/fuel ratio controllers in an independent test vs. 17 competitors wideband AFR controllers Patented X-Digital wideband technology (Patent 9,575,030) The fastest wideband controller now comes standard with a more durable wideband sensor at no additional cost!The AEM/FAE sensor lasts up to 3x longer than the Bosch 4.9 LSU with a 10% faster response time in testing Factory calibrated resistor does not require free-air calibration, but technology allows for free-air calibration as sensor ages if user desires Compatible with vehicle/system voltages up to 16V 0-5V & RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders Can display AFR values in hundredths of % 52mm gauge diameter and slim 0.825?ǥ gauge depth Gauge cup depth only .200?ǥ deep! Auto dimming feature User configurable display via buttons on the gauge face
