Wideband sensor: A Wideband sensor measures the air-fuel ratio (AFR) in the exhaust gases over a wide range of conditions. Unlike narrowband oxygen sensors (which most GM vehicles we offer tuning for have), which can only indicate whether the AFR is richer or leaner than the stoichiometric point using narrow band sensors is not the best way to determine AFR in high performance applications this is why we require a wideband sensor.

Recommended wideband sensor: AEM 30-0334 X-Series
