PWC Operational Differences
The PWC Plug-In ECU closely mimics the standard OEM operation. However,
MoTeC would like to draw your attention to some operational differences
when a PWC Plug-In ECU is installed.
ECU Operation
The M400 Marine ECU engine control functionality is the same as the
standard factory ECU; all normal operations of the PWC are possible, with the
exception of Learner Key Mode.
Instrument Cluster Operation
The M400 Marine ECU will control the Kawasaki instrument cluster
mimic the original factory dash operation.
The ECU controls the dash via the KTC (K-Line to CAN) data
KTC receives CAN messages from the ECU, and then transmits K
messages to the instrument cluster.
The fixed CAN address and the CAN messages custom data set are
in the Base Map and should not be changed.
To prevent engine damage the following dash alarms and rev limits are
provided:

Dash alarm
Oil Temperature

Yes
Water Temperature

°C (244 F)
Yes
Intercooler Temperature
160
°C (320 F)
Yes
Oil Pressure
No Oil Pressure
and RPM > 3000
Yes
Note: These alarms and rev limits are similar to the factory settings.
Cooling
When a PWC Plug-In ECU is fitted the engine power is increased. The
standard Kawasaki oil and water cooling system might not be sufficient and
engine over-heating can occur.
If the engine overheats a relevant dash alarm will come on and the rev
be limited to prevent engine damage.
