The ECM uses inputs from sensors throughout the motor to monitor operating conditions and adjust the various functions as needed. The ECM also stores diagnostic codes that can be used to troubleshoot engine problems.
Here are some of the specific functions of the Mercury 8M0059347 / 8M0059365 ECM:
- Controls the engine speed, fuel injection, and other engine functions
- Controls the ignition timing and other ignition functions
- Controls the fuel injection system, such as the fuel pressure and flow rate
