The Kotuku Engine Data Unit is a CanFly® component that can monitor most engine parameters for a 4 or 6 cylinder engine.
- 4/6 EGT channels for K type EGT probes (must be ordered separately).
- 4/6 CHT channels for K type thermo well CHT probes (must be ordered separately).
- Oil Pressure sensor (must be ordered separately).
- Fuel Pressor sensor (must be ordered separately).
- Fuel Flow sensor (must be ordered separately).
- Bus voltage.
- Bus current, requires an external current shunt (must be ordered separately).
- Outside air temperature sensor (must be ordered separately).
- Left/Right fuel quantity, uses standard restive sensors (must be ordered separately).
- Left/Right tachometer. When both are connected the kEDU will generate timing divergence alarms.
- Manifold pressure sensor (must be ordered separately).

kMAG Integration
When used as part of the CanFly® Lycoming Engine Management solution the kEDU can perform the following additional roles:
- The Fuel Pressure sensor from each kMAG is averaged and replaces the kEDU sensor data.
- The Inlet Air Temperature from each kMAG is averaged and published.
- The Manifold Pressure from each kMAG is averaged and publisished this replaces the kEDU MAP sensor data. The kEDU MAP sensor is then used as a barometric air pressure sensor.
- Automatic lean-find. Only supported if 2 kMAG's are active and the mixture lever is set to Auto Mixture mode.
Alarms
The EDU can generate the following alarms, that can be displayed on a CanFly® display:
- Low Oil Pressure
- Low Fuel Pressure
- High Oil Temperature
- High Cylinder Head Temperature (1-6)
- High Exhaust Gas Temperature (1-6)
- Timing Divergence
- Low Fuel Quantity
- High Fuel Pressure
- CHT Cold Shock
- High RPM
- Bus Voltage High
- Bus Voltage Low
- High Current
- kMAG RPM Divergence (requires 2 kMAG)
- kMAG MAP Divergence (requires 2 kMAG)
- kMAG IAT Divergence (requires 2 kMAG)
- kMAG Fuel Pressure Divergence (requires 2 kMAG)
- kMAG Temperature High
- Low Fuel Flow
In addition the CanFly® Commander application can define custom alarms on any published CanFly® data point.
Data Logger
The kEDU contains storage for a large number of data elements. The CanFly® Commander can configure the data logger to store any CanFly® data element.
The default data logger logs the following, at 6 second intervals:
- EGT (either 4 or 6 depending on the engine).
- CHT (either 4 or 6 depending on the engine).
- RPM
- Oil Pressure
- Oil Temperature
- Fuel Flow
- Altitude (Requires a kHUB, kAHRS or external barometric sensor).
- Airspeed (Requires a kHUB or kAHRS)
The eEDU can store at least 5 hours of data, when it is full the oldest entries are replaced.
