For fast response times, AEM X-Series wideband UEGO air/fuel sensor controller gauges are a great option! Built on the unique, patent-pending X-Digital technology, they report accurate information quickly— enabling you to tune your engine more efficiently. These gauges have modern, visually striking faceplates with 7-segment center displays that are 87 percent larger. They're ultra-slim and come with black bezels and black dual-faced faceplates for air/fuel and Lambda. The displays are user-configurable and feature auto-dimming.

  • 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 16 V
  • 0-5 V and 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 a percent
  • 52mm gauge diameter and slim 0.825 in. gauge depth
  • Gauge cup depth only .200 in. deep
  • Locking connectors
  • Bosch 4.9LSU wideband UEGO sensor

X-DIGITAL TECHNOLOGY

X-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition. The controller’s high speed digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.

WHY RESPONSE TIME MATTERS

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 (transport delay) can affect deadtime, it is not the only source. Often, the sensing elements response to the gas is the largest contributor to deadtime when an engine is in high RPM under load.
