MoTeC Sea-Doo 2004 – 2009 Installation
Installation
The M400 Marine ECU replaces the factory ECU on top of the engine.
Remove the factory ECU (four M6 bolts) and screw three anti
mounts into three of the mounting holes (see picture).
Screw the Sea-Doo ECU mounting plate to the anti-vibration mounts using
Loctite 243 and M6x10 stainless steel countersunk screws.
Then, place the rubber backing pad on the plate and secure the M400 Marine
ECU with the Mounting brackets using four M6x16 stainless s
and four M6 stainless steel spring washers.
Finally, connect the adaptor loom harness between the M400 ECU and the
factory wiring harness.
Note – the Sea-Doo connectors are labelled A and B and are keyed so
that only the correct plug can be inserted. If the slide-lock on the plug
will not slide shut, then the plug is fitted into the wrong connector.
For the ECU to function normally all supplied devices must be connected:
•
STC-S device plugged into 6 pin socket labelled ‘STC’
•
IGN4 device plugged into 6 pin socket labelled ‘COIL’ and 4 pin
socket labelled ‘IGN’.
•
DMC-F device plugged into 12 pin socket labelled ‘DMC’.
These devices can all be secured by zip-ties.
