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.
