This is the successor to the original NGK AFX wideband package. This wideband, like the original AFX, is manufactured by ECM which makes the equipment used by all major OEMs and agencies and is the world leader in lambda instrumentation.
The AFX2 features a user selectable display for gasoline/methanol/lambda readouts as well as two optional ranges of measurement (either 0.618 to 1.098 lambda or 0.411 to 1.373 lambda). These options are chosen using jumpers on the board. The analog output connects to any 0-5V input for easy transfer of the reading to a data logger.

Each AFX2 includes the display/controller box, a harness, and a brand new NTK 24302 O2 sensor.
