Detail: The array of lambda values corresponding to pump values for a given sensor type and fuel. The entries in the
array can be user edited. The default values are valid calibrations for gasoline and diesel fuel.
EGO X Cluster
EGOX_Enable
Tip Strip: Enables EGO channel
Detail: Allows each individual sensor interface to be enabled or disabled.
EGOX_Sensor
Tip Strip: EGO Sensor Voltage
Detail: The voltage being sourced by the EGO sensor.
EGOX_Status
Tip Strip: EGO Sensor Status
Detail: Indicates EGO sensor status
COLD SENSOR: When a narrow-band sensor is cold, the sensor input circuit will report a voltage of approximately
450 millivolts and will not fluctuate with rich and lean exhaust mixtures. This enumeration is reported when the
sensor value remains in the range of 400 to 500 millivolts for a period of 1 second.
FOULED SENSOR: When a narrow-band sensor is fouled or aged, the sensor value will transition from rich to lean
and from lean to rich much slower than that of a normally operating sensor. This enumeration is reported when the
sensor value takes longer than 1 second to transition from below 300 millivolts to above 600 millivolts or vice versa.
RICH: The sensor is sourcing a voltage of greater than 600 millivolts.
LEAN: The sensor is sourcing a voltage of less than 300 millivolts.
