DIAGNOSTIC SOFTWARE FUNCTIONS
Ignition Timing
Use the Ignition Timing screen to check and
adjust EMM timing. EMM timing must be synchro-
nized to crankshaft position.
Refer to TIMING ADJUSTMENTS on p. 112.
Check timing after any of the following proce-
dures:
•
Powerhead replacement
•
Crankshaft replacement
•
Flywheel removal or replacement
•
CPS replacement
•
EMM replacement
•
EMM software replacement
IMPORTANT:
Make sure the timing pointer is
set and the outboard reaches operating tempera-
ture before making adjustments.
TPS Calibration
TPS Calibration synchronizes throttle plate open-
ing with throttle position sensor voltage.
Refer to TPS CALIBRATION on p. 113.
Perform TPS Calibration after replacing or adjust-
ing any throttle body or throttle linkage parts.
Fuel Injector Servicing
All E-TEC fuel injectors use software program-
ming to compensate for variations in fuel flow.
Each injector and its location on the outboard is
identified by the
EMM . DO NOT install an injector
without updating the compensation software.
To install a service injector, click the “Replace”
button on the
Injector Coefficients screen and
select the file for the replacement injector. Refer to
Fuel Injector Service on p. 147.
