MoTeC PWC Plug-In ECU - Manual (Page 24)

MoTeC Sea-Doo 2004 – 2009 Installation
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 and Knock Sensing.
Instrument Cluster Operation
The M400 Marine ECU will control the Sea-Doo Instrument cluster and mimic
the original factory dash operation.
The ECU controls the dash via the STC (Serial to CAN) data adaptor; the
STC receives serial RS232 messages from the ECU, and then transmits
messages to the instrument cluster.
The serial RS232 transmit settings and the CAN custom data set are provided
in the Base Map and should not be changed.
To prevent engine damage the following dash alarms and rev limits are
provided:
Sensor Value Dash Alarm
Fuel Tank Level < 10% capacity Yes
Battery Voltage <11.6 V or >15.2 V Yes
Engine
Temperature 110°C Yes
Exhaust
Temperature 110°C Yes
Oil Pressure No Oil Pressure
and RPM > 3300 Yes
Note: These alarms and rev limits are similar to the factory settings.
