AEM Digital Wideband O2 AFR UEGO Gauge (part number 30-4110NS) combines an air/fuel ratio controller (AFR) and gauge in one unit. It offers accurate and fast AFR readings with a user-friendly digital LED display and a colored LED needle. For optimal performance, AEM recommends using the Bosch 4.9LSU sensor with this gauge. This sensor eliminates the need for free-air calibration, unlike some competitor sensors.
Features:
• Controller gauge and hardware sold without wideband sensor
• No free air sensor calibration required - ever
• 52mm (2-1/16") gauge housing
• 0-5v analog output (10-20 AFR range only)
