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 response to the gas is the largest contributor to deadtime.When tuning an engine using wideband AFR feedback control, deadtime affects the data you are looking at because it is reported in a different operating location than when it occurred. This means whatever changes you make to the base fueling will likely be in the wrong timeframe. This can be particularly dangerous to high cylinder pressure applications, and EFI systems that use feedback control.

Installation Instructions
Installation Instructions
  • 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
  • 0-5V & RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders
  • Black bezel and black double-sided faceplate included (silver bezel/white faceplate option sold separately, PN 30-0300-ACC)
  • Factory calibrated resistor does not require free-air calibration, but can be free-air calibrated
  • User-configurable display for changing between AFR, Lambda, and O2%, and 3- or 4-digit display
  • 52mm gauge diameter and slim 0.825" gauge depth(Gauge cup depth only .200" deep)
  • Auto-Sensor Detection between AEM FAE and Bosch LSU 4.9 wideband sensors
  • Patented X-Digital wideband technology (Patent 9,575,030)
