Digital segment display and LED radial bar graph display. 12 and 16 volt compatible, compatible with nearly every street car or race car electrical system.

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 wideband 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.
