miniDaqu — Manual 8.1 CC-m Module
This section gives some specific installation tips for the MWfly engines. MWfly
engines are equipped with ECU that has a CAN output. However, Daqu can
not be directly connected to this ECU and an interface is needed. This inter-
face is called
CC-m CAN to CAN module and it is provided by MWfly.
8.1 CC-m Module
The module is equipped with a D-SUB 9 male connector. Please refer to the
CC-m module documentation for proper pin out and details.
CAN Aerospace low and high pins from the CC-m connector shall be con-
nected to the Daqu ECU connector. Ground is usually not connected. Figure
23 shows connection schematics.

9 Additional Sensors
Most of engine data is transmitted ECU. However, some additional sensors
may be connected to mini Daqu, which either supplement or override infor-
mation from ECU.
When a sensor is connected and activated on Daqu and engine ECU already
provides such sensor, the sensor connected on Daqu takes priority and over-
rides values from ECU.
