MoTeC PWC Plug-In ECU - Manual (Page 14)

MoTeC Yamaha Installation
The CAN connection should re-establish and you may continue with
tuning adjustments.
Power-up Adaptor Wire
If the ECU needs to be powered for longer than 30 seconds without the
engine running, for example when downloading large logging
adjustments, the ECU power should be controlled externally.
For this purpose, a separate wire is available from the Adaptor
Connect this wire to ground via a switch, to turn on the ECU power relay.
Note: Do not use ground wires from the M400 pins B14, B15 or B16 for this
earth. Use either pins A10 or A11 or a chassis ground. (see Appendices for
Pin List by Function)
When finished, this wire should be lifted from ground to return to normal
power control operation, so the ECU has control of the power relay. Failure to
do so will cause the battery to go flat.
Security
The standard Yamaha Immobiliser system uses a Key Fob transmitter to
Lock/Unlock the PWC. If the immobiliser is locked, the Start button will not
crank the engine, thus preventing operation.
When the PWC Plug-In ECU is installed an Immobiliser Bypass device
renders the craft permanently unlocked.
It is important to secure the craft when not in use, for example by
the Immobiliser Bypass.
