3.2.4.1.8 Lambda-control
A standard (narrow band) BOSCH lambda sensor or one of
the KMS UEGO controllers (recommended) can be
connected to the system. Select the relevant lambda
sensor in the menu (top left).
When the engine is running, the A/F ratio/lambda ratio will
show in the communication bar.
It is also possible to connect a second lambda sensor/UEGO
controller to the system. This 2
nd
sensor/controller has to
be the same as the first one.
3.2.4.1.8.1 Adjustment of air fuel ratio feedback control
Lambda controller type:
Via this menu you can specify the lambda sensor/controller in use. For wideband sensors, the input
signal is via the included controller, while standard narrow band BOSCH lambda sensors can be
connected directly to the ECU.
Warning:
When you have a KMS UEGO Display controller you can choose 3 different
types of output signal (type a,b and c). Always check if the output type is
the same as selected in this software. Type ‘a’ of the KMS UEGO Display
controller has the same output curve as the KMS UEGO controller.
Use Lambda sensor:
There are different options in this submenu:
Use lambda sensor: 1 with correction on injection group 1
2 with correction on injection group 1
You can select on which attached oxygen sensor the correction has to work.
Lambda scaling:
In this menu the values of the different types of sensors/controllers are visible (not adjustable). The
KMS UEGO (display) controllers are pre-calibrated.
A/F to Lambda (or vice versa):
All the ECUs are standard set to A/F ratio. You can change all the settings of your ECU to Lambda
values. All values will be converted. It is always possible to switch back to A/F ratio.
When you switch between A/F and Lambda, these settings have
to be saved in the ECU. The KMS software will do this
automatically. When ‘yes’ is selected in the pop-up screen, the
software will start downloading to the ECU. It will
automatically lock the settings after downloading.
Idle A/F mix:
