The AutoMeter 2-1/16in C2/S Wide Band Air/Fuel Gauge (Model 7178) is an essential tuning instrument for serious engine builders and performance mechanics who demand real-time combustion data. This gauge is particularly useful for those tuning naturally aspirated builds or managing forced induction setups, providing critical feedback to optimize fuel mixtures across the entire RPM range.
Utilizing a wideband oxygen sensor, this gauge offers continuous air/fuel ratio readings, unlike narrowband sensors that only indicate rich or lean conditions. Its robust construction is designed to withstand the heat, vibration, and electrical noise typical in modified engine bays, ensuring reliable performance across various fuel systems, including carburetors and both port and direct injection.
This gauge is ideal for anyone pushing beyond factory fuel mapping, making it a valuable tool for both street and competition applications. Note that the AutoMeter wideband controller is sold separately, which is necessary for operation. Its 2-1/16-inch diameter allows for easy integration into standard automotive gauge clusters or dash pods.
