AEM Digital Wideband UEGO Gauge

Delivering precise air/fuel monitoring for tuning or track use, this AEM digital wideband UEGO solution combines a fast, accurate wideband AFR controller with an easy-to-read digital LED display and sweeping LED needle that changes color as the mixture moves from rich to lean. Designed for tuners who need reliable AFR feedback, the unit accepts LSU sensors and provides laboratory-calibrated readings without the frequent free-air calibration required by some competitors, making it a practical, high-performance choice for engine tuning and data logging.

Features:

• Digital LED display with sweeping LED needle
• Color-changing LED needle for rich-to-lean
• Wideband UEGO AFR controller and gauge
• Uses 4.9 LSU sensor (supersedes 4.2 LSU)
• Individually laboratory-calibrated LSU sensors
• No free-air calibration required
• Direct tuning feedback for accurate AFR monitoring

Important Note:

NOTE: The 30-4100 Wideband UEGO Gauge Controller that uses the 4.2 LSU sensor will be superseded to the 30-4110 Wideband UEGO Gauge Controller that uses the 4.9 LSU sensor in August 2014. Instructions for the 30-4100 will still be available in the Instructions tab after this change.
