• Black bezel and black dual faced faceplate, silver bezel/white gauge option included.
• Display Lambda values from .55 to 2.00
• Factory calibrated resistor does not require free-air calibration, but technology allows for free-air calibration as sensor ages if user desires.
• Includes Bosch 4.9LSU wideband UEGO sensor. 52mm gauge diameter and slim 0.825” gauge depth.

AEM

• Interchangeable black and white faceplates included for customizing gauge appearance
• Bosch 4.9 LSU wideband sensor and weld-in bung included PN 30-4110
• No free air sensor calibration required ever
• Interchangeable black and silver bezels included
• 0-5V analog output 10-20 AFR range only

Innovate Motorsports

• The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) features a modern, visually striking faceplate and new seven-segment center display that is 87% larger than the 30-4110 AEM
• The gauge includes a 0-5v and RS232 serial port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging
• 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
• Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune
• When tuning an engine using wide-band AFR feedback control on an inertia dyno, dead time affects the data you are looking at because it is reported in a different operating location than when it actually occurred

AEM
