DIAGNOSTIC SOFTWARE FUNCTIONS
TPS Calibration
TPS Calibration synchronizes throttle plate open-
ing with throttle position sensor voltage.
Refer to TPS Calibration on p. 118.
Perform TPS Calibration after replacing or adjust-
ing any throttle body or throttle linkage parts.
Idle Speed Control
Use the Idle Adjust function to increase or
decrease IN GEAR IDLE speed. This adjustment
offsets the basic EMM programming and will not
set an absolute fixed speed. After the offset is
changed, the EMM continues to control engine
operation normally. Engine idle speed is not fixed.
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. 150.
