The AEM 30-4110 Digital Wideband UEGO Gauge delivers precise air-fuel ratio monitoring with 0.1 AFR accuracy using the Bosch LSU 4.9 wideband UEGO sensor. Unlike the X-Series gauges, the AEM 30-4110 uses a traditional digital display face rather than the newer X-Digital format, making it a preferred option for builders who want a clean, functional readout without secondary display modes. The 30-4110 operates on 8-18V, reads from 10:1 to 20:1 AFR, and outputs a 0-5V analog signal for datalogger integration. A 52mm housing fits any standard gauge panel or A-pillar pod.

AEM Performance Electronics has been developing aftermarket performance electronics for over 30 years from Hawthorne, California. AEM produces wideband controllers, standalone ECUs, boost gauges, and data acquisition systems trusted by professional race teams and performance enthusiasts worldwide. The 30-4110 represents AEM's original digital wideband gauge platform, valued for its reliability and straightforward AFR display.
The AEM 30-4110 is AEM's classic digital wideband gauge with a traditional digital display, while the 30-0300 uses AEM's newer X-Digital technology with a simultaneous AFR/lambda dual-display face. Both use the Bosch LSU 4.9 sensor and read 10:1-20:1 AFR. The 30-4110 is the original platform; the 30-0300 is the current generation X-Series design.
What sensor does the AEM 30-4110 use?The AEM 30-4110 uses the Bosch LSU 4.9 wideband UEGO sensor, which is included in the kit. The LSU 4.9 is the industry standard wideband sensor used in performance tuning and motorsport applications.
What AFR accuracy does the 30-4110 provide?The AEM 30-4110 provides 0.1 AFR accuracy across its 10:1-20:1 reading range with the Bosch LSU 4.9 sensor. This level of accuracy is sufficient for performance tuning, dyno sessions, and street monitoring applications.
Does the AEM 30-4110 have an analog output for data logging?Yes. The 30-4110 includes a 0-5V analog output for connection to dataloggers, standalone ECUs, or piggyback fuel controllers that accept a wideband voltage reference signal.
Is the AEM 30-4110 compatible with E85?Yes. The AEM 30-4110 works with E85, gasoline, methanol, and other common fuel blends. Users should account for E85's different stoichiometric AFR when interpreting gauge readings, as the ideal AFR target for E85 is approximately 9.8:1 versus 14.7:1 for gasoline.
What gauge panel size does the 30-4110 fit?The AEM 30-4110 uses a 52mm gauge housing, which is the standard metric gauge size for A-pillar pods, custom dash panels, and roll cage mounting brackets used in performance builds.
Does the 30-4110 work on a diesel engine?The AEM 30-4110 can function on a diesel application, though diesel uses a different oxygen content model than gasoline. The gauge will display accurate lambda/oxygen data, but interpreting AFR numbers for diesel requires understanding different lambda targets versus gasoline tuning.
Is the AEM 30-4110 covered by a warranty?AEM Performance Electronics provides a limited warranty on their gauge products against defects in materials and workmanship. Refer to the included documentation or AEM's website for current warranty terms and conditions for the 30-4110.

Aftermarket performance gauges give drivers accurate, real-time information about critical engine and drivetrain parameters that factory instrument clusters either omit or display too imprecisely for performance or modified vehicle use. Oil pressure, coolant temperature, boost pressure, exhaust gas temperature, transmission temperature, and wideband air-fuel ratio are the most important parameters that performance gauges monitor, each providing specific early warning data that protects expensive drivetrain components from damage. The difference between catching an oil pressure drop before engine failure and finding out about it afterward often comes down to having accurate gauges in visible positions. Modern analog and digital gauges from brands like Autometer, Glowshift, Speedhut, and AEM are brighter, more accurate, and more reliable than ever before, making an aftermarket gauge installation a practical investment for any modified vehicle.

Performance gauges and gauge pods form a complete driver information system for any modified or performance vehicle, combining accurate instrument measurement with a mounting solution that keeps critical engine data visible without cluttering the interior. Gauge kits that bundle the gauge head with a compatible pod create a finished, coordinated installation that looks intentional rather than improvised. Whether monitoring boost on a turbocharged build, oil pressure on a high-revving naturally aspirated engine, or exhaust gas temperature on a diesel truck that tows near its limit, the combination of a quality gauge and a proper pod mount is the correct approach. Both A-pillar and dash pod solutions are available for the most popular domestic and import performance vehicles. Popular Upgrades Autometer Sport-Comp and Ultra-Lite gauge and pod bundles for the Mustang, Camaro, WRX/STI, and F-150 are the most popular combination purchases, providing a matched gauge and vehicle-specific A-...
