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 less complex than
standard factory ECU; only one mode is supported. The handlebar Mode
switching does not operate as in the stock craft.
STC-SX Device
This craft depends heavily upon CAN bus communication for correct
operation. Both the Instrument Cluster and Brake System (see below) use
CAN data for critical decisions. The M400 ECU transmits and receives
relevant data via the STC-SX device using Custom Data Set 1.
account should this table be changed as Brake System or Instrument
Cluster malfunction may result.
If for any reason these systems do not operate correctly, the configuration file
and the STC-SX device should be checked first.
iBR Brake System Operation
The iBR system works in conjunction with the Brake Lever, ECU and
Instrument Cluster to determine how the brake will operate. The interaction is
complex and not user-adjustable. On no account should Custom Data Set
1 be changed as Brake system malfunction may result.
If for any reason the iBR unit is not satisfied with data received from the othe
components, the Instrument Cluster will illuminate the red IBR warning light
and the brake system will no longer operate.
In this situation the craft must be shut down and restarted before the
IBR system will be fully functional: Remove the Lanyard, wait 10
seconds, then re-install the Lanyard and re-start the engine.
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-SX (Serial to CAN) data adaptor; the
STC-SX receives CAN messages from the ECU, and then re
messages to the instrument cluster.
