controller is used and linear signal is connected to EMU.
Oxygen sensor measures Lambda value of mixture. To obtain
adequate AFR measurement, correct fuel type must be selected here.
Sensor heater PID controller kP coefficient. Preset value should not
be changed
Sensor heater PID controller kI coefficient. Preset value should not be
changed
Sensor heater PID controller kD coefficient. Preset value should not
be changed
Sensor heater PID controller integral windup limit. Preset value should
not be changed.
Sensor pump cell PID controller kP coefficient. Preset value should
not be changed.
Sensor pump cell PID controller kI coefficient. Preset value should not
be changed.
Sensor pump cell PID controller kD coefficient. Preset value should
not be changed.
Sensor pump cell PID controller integral windup limit. Preset value
should not be changed.
Calibrating resistor value. Rcal resistance can be measured on
terminals 2 and 6 of wide band sensor. Correct Rcal value should be
in 30-300 ohm range and is essential for accurate measuring results.
When selected, sensor heater is enabled when EMU is powered,
unlike in normal operation mode, when heater is enabled after engine
is started. This mode can be used to measure mixture ratio during
engine startup.
If heater is enabled when condensation is still present in exhaust
system, sensor could be damaged, so for normal use, it is advised to
disable this option.
In case of external sensor controller, defines AFR value at 0Vvoltage.
In case of external sensor controller, defines AFR value at 5Vvoltage.
Analog input used to connect external sensor controller.
In case of narrow band sensor, option enables heater output to drive
the sensor heater.
