M163 UEGO Lambda Controller Bosch double

USER MANUAL

Warning!!! To display the correct value of A/F, before attaching a probe to the
connector it is essential to set in M163 module “the identification code for
calibration” five figures reported on the probe itself. This parameters is a unique
code associated with each sensor that allows M163 to perform compensation and
must therefore be set again each time you used different probes or the probe are
connected to different channels. So for each module using always make sure the
probes are connected to the correct channel. For details on how to settings the code
refer to the “mode setting parameters”.

Display modes

The M163 module can have two pages to display data acquired in each of which are expressed
respectively in ratio A/F or Lambda (A/F ratio measured in relation to the value of A/F
stoichiometric).
After a short message at startup, the system displays on the last page before the shutdown.
It’s possible switch from one display mode to another by a simply press to the right button “<>”.

How to set parameters

The M163 module allows you to set for each channel the following parameters:

- IDs for calibration of the probes connected to the channels.

- IDs of CAN channels where data probes are transmitted.

- Transmission speed of both CAN channels

To change Calibration IDs or CAN IDs parameters, press left button “◊” until you see parameter to
change. Pressing the right button “<>” you can entry in the mode of “edit”.
In this mode you can change the single digit of the parameter to be amended by selecting the right
key “<>”. The figure selected, which is marked with the symbol “^”, can be increased later by
pressing left button “◊”. Reached value “F”, with an additional pressure of the left button. “◊”, you
get the reset of the figure itself.
The parameter is changed and saved when you selected the last digit, making a further press left
“<>”.
To change CAN Transmission Speed, press left button “◊” until you see this parameter on display.
Pressing the right button “<>” you can entry in the “edit” mode. In this mode you can select the
available CAN transmission speed (1Mbit/sec or 500kbit/sec) by pressing, repeatedly,

left button

“◊” until you see the wished value. The parameter is changed and saved by pressing left button
“<>”.
