Wideband O2

Wideband O2

A Wideband O2 sensor can be used by the ECU for monitoring and protection purposes, or for closed-loop O2 Control. A wideband sensor, by definition, measures a broad section of the AFR scale. As such, a Wideband O2 sensor is the preferred sensor to be used for accurate engine tuning. 



This node allows you to specify the number of wideband sensors, their position and input type. For each enabled wideband sensor, a specific Sensor node will be added to the Wideband O2 navigation tree for settings related to that specific sensor.



Engine Protection

      
       If enabled, the Wideband sensor operating conditions can be monitored, and a DTC flag triggered if the monitored Wideband value goes above a certain threshold. The Wideband Maximum table specifies the maximum wideband value when within the parameters defined in the Engine Protection settings. This table is user configurable and can be mapped against and channel in 3D. 

      Wideband Maximum - sets the maximum allowable AFR. Any measured AFR above this for the duration of the Delay Time will trigger the DTC when the preconditions are met.
      Minimum RPM - sets the RPM above which the system will monitor the Maximum AFR
      Precondition - Use MAP, TPS or a combination as a selected load threshold for the DTC system to operate
      Minimum MAP - sets the minimum manifold pressure value that the system will operate at.
      Minimum TPS - sets the minimum TPS value that the system will operate at.
      Delay Time - sets the time the AFR must rise above the Maximum before the DTC will be triggered.
      DTC Severity - Sets the level of severity when the Wideband safety system triggers.

Diagnostics



This node calibrates the DTC options for the Wideband Sensor. 
If using an On-board/CAN Wideband Controller the minimum and maximum voltage DTCs will be disabled.

Wiring


This node allows you to assign the wiring or CAN connection for each enabled wideband sensor.

For inputs or Wideband controllers that support multiple sensor types, the sensor type can be specified here.
