MoTeC Yamaha Apex Installation 5
Snowmobile Operational Differences
The Snowmobile Plug-In ECU closely mimics the standard OEM operation.
However, MoTeC would like to draw your attention to some operational
differences when a Snowmobile 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 Snowmobile are
possible, with the exception of Thumb Warmer and Grip Warmer
operation, which are fully functional but slightly different in operation – see
below.
Instrument Cluster Operation
The M400 Marine ECU will control the Yamaha instrument clusters and
mimic the original factory dash operation.
The ECU controls the dash via the KTC (K-Line to CAN) data adaptor; the
KTC receives CAN messages from the ECU, and then transmits K-Line
messages to the instrument cluster.
The fixed CAN address and the CAN messages 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 Rev Limit
Engine
Temperature approx. 92
°C (194 F)
yes None
Oil Pressure None yes 4500 rpm
Note: These alarms and rev limits are similar to the factory settings.
Power Control Strategy
The standard Yamaha Apex uses an Ignition Key and Kill Switch to power
up the vehicle. If the Kill Switch is raised, turning the Ignition key to the
Start position will start and run the engine.
