Installation
Installation of a replacement injector requires that
coefficient data for the new injector is uploaded to
the EMM.
Coefficient data for some replacement injectors is
supplied on a computer disk shipped with the
injector. If a disk is not included with the injector,
coefficient data can be downloaded from the Evin-
rude/Johnson dealer website. Refer to the instruc-
tions provided with the injector kit.
Upload Coefficient Files to EMM
IMPORTANT: If using Diagnostic Power Supply
Tool, P/N 587005, to supply power to the EMM,
use Accessory Power Cable Kit, P/N 5008092, to
connect an external 12 volt battery to the Power
Supply Tool.
If the internal batteries of the Power Supply Tool
have a low voltage condition the EMM could turn
OFF during the coefficient upload, resulting in a
failed update.
Use the Evinrude Diagnostics software Settings
screen to upload the coefficient file to the EMM.
Select the Injectors tab.
Select the cylinder tab for injector being replaced.
