Wideband AFR Kit

AEM Wideband Gauge, Controller and Sensor - used to accurately measure the air-fuel ratios (AFR) when tuning an engine.

With a 52mm gauge that has a 3-digit digital LED display and needle that changes colour as the AFR goes from rich (10:1) to lean (20:1). Accurate to 0.1 AFR and reads in real-time in either AFR or Lambda. A Bosch wideband sensor is included and the controller is built into the gauge.

This tool can be used for both fuel-injection and carburettor applications. It can also be integrated with almost all programmable engine management or data-logging systems, via the user-programmable 0-5V analogue output.
