30-4110NS Wideband Controller Gauge Kit

The AEM Classic Digital Wideband AFR Gauge (Part # 30-4110NS) is a performance instrument designed to provide accurate Air/Fuel Ratio (AFR) monitoring. This kit is sold without a wideband sensor, offering flexibility for users to source a compatible Bosch 4.9LSU sensor independently, potentially reducing costs. The gauge itself features a clear, digital LED display and an LED "needle" that visually indicates changes in AFR from rich to lean, providing at-a-glance monitoring critical for engine tuning. This gauge is housed in a standard 52mm (2-1/16") housing, making it compatible with most existing gauge pods and installations. It provides a 0-5v analog output signal, specifically for the 10-20 AFR range, which is essential for data logging and integration with engine management systems. A key benefit highlighted by AEM is that this gauge, when used with approved sensors, does not require the often-inconvenient free-air calibration procedure that some competing products necessitate. Installation is noted as requiring a good understanding of automotive electronics and mechanics. Accurate AFR data is crucial for optimizing engine performance and preventing damage. Running too rich can lead to power loss, while running too lean can cause severe engine damage. This AEM wideband controller acts as a powerful and cost-effective tuning tool, allowing tuners to precisely monitor AFR and make necessary adjustments to maximize power and efficiency. The product comes with a manufacturer's 1-year warranty.
