AEM Digital Wideband UEGO Gauge

Legendary Precise AEM Digital Wideband UEGO Gauge—Your Tool to Dialing in Your Tune

Why enthusiasts choose this gauge

• Lab-grade accuracy you can trust – The included Bosch 4.9 LSU sensor reads within 0.1 AFR, reacting lightning-fast to transient throttle changes so your data log is always one step ahead of detonation.
• Simple, glance-able readout – A large three-digit LED shows AFR in 0.1 increments, while the outer “needle” ring sweeps from rich (amber) to lean (green/red) for instant visual feedback when you’re flat-out.
• Totally plug-n-play with any ECU – 0-5 V analog output and AEMnet CAN signal make it compatible with standalones, piggybacks, and data loggers alike. No calibration gas required; just wire it, thread it, and go.
• Looks at home in any cockpit – Mix and match the included black/silver bezels and black/white faces until the gauge matches your interior vibe. Standard 52 mm (2-1/16") size fits most pods.
• Built to last – Rugged, weather-resistant internals shrug off vibration and heat, backed by AEM’s race-proven reliability.

Perfect for: turbo builds chasing safe boost, naturally aspirated engines squeezing every last horsepower, ethanol conversions, and anyone who refuses to gamble with expensive hardware.
