MoTeC would like to draw your attention to
some operational differences
when a PWC Plug-In ECU is installed.

ECU engine control functionality is the same as the
standard factory ECU; all normal operations of the PWC
exception of No Wake Mode and Cruise Control.

is a safety related device. If it is not functioning
correctly contact your MoTeC dealer for further advice.
Warning:
