To Change MPEM/ECU Options on Siemens ECU models :
NOTE: The options selected must match the options you have on your watercraft. Check your
wiring diagram and watercraft carefully to ensure that you have all the proper options selected. It
has been observed that these watercraft "lose" their options settings for no apparent reason (it is
speculated that it happens if the battery is disconnected or low for a long period of time). If the
options selected do not match what is installed on the watercraft, the option will not work properly
and may trigger a fault. NOTE: Bosch ECU models automatically determine the proper settings,
there will be no check boxes on these models.
 For each option present on the watercraft, ensure that a check mark is in the box next to
the option.
 If an option is present but there is no checkbox, simply check the box next to the option.
 If an option is not present on the watercraft, but there is a check in the box next to the
option, click on the box to remove the check mark
 Any changes need to be written to the ECU. Select Vehicle and Write Vehicle.
After you select Write, a popup box will instruct you to remove the key and wait until the connect
light is off to complete the write operation. (a box will not popup on 2009 and newer models with
the iControl system; you do not need to remove the key on these models) Follow the instructions in
the box, and especially take note that on 2007 and newer models, you need to take the key off, put
it back on, then remove again to complete the write operation.
