Description

X-Series Wideband UEGO AFR Sensor Controller Gauge with X-Digital Technology. Includes: X-Series Wideband Controller Gauge, Bosch LSU 4.9 Sensor, Wiring Harnesses, Black Bezel, Black AFR/Lambda Faceplate & O2 Sensor Bung

Product Overview

Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases can affect deadtime, it is not the only source. Often, the sensing element’s respon


Features and Benefits

  • X-Series Wideband UEGO AFR Controller Gauges were the fastest responding wideband air/fuel ratio controllers in an independent test vs. 17 competitor wideband AFR controllers
  • Patented X-Digital wideband technology (Patent 9,575,030)
  • Factory calibrated resistor does not require free-air calibration, but can be free-air calibrated
  • Auto-Sensor Detection between AEM FAE and Bosch LSU 4.9 wideband sensors
  • Compatible with supply 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
  • 52mm gauge diameter and slim 0.825" gauge depth(Gauge cup depth only .200" deep)
  • Auto-dimming feature
  • User-configurable display for changing between AFR, Lambda, and O2%, and 3- or 4-digit display
  • Black bezel and black double-sided faceplate included (silver bezel/white faceplate option sold separately, PN 30-0300-ACC)
