System configuration parameters are parameters that affect the emissions and the power of the engine. Default values for the parameters are programmed at the factory. The values for certain configuration parameters are stamped on the Engine Information Plate.

Some values may be changed by the customer in order to suit the needs of the specific application. The values are programmed with the AVSpare Electronic Technician (ET).

If the parameters that are protected with the factory passwords are changed, the AVSpare warranty may be voided.

Note: The "ECM Identification Parameters" must be programmed if the ECM is replaced and/or you reprogram the engine rating. It is not necessary to reprogram the "ECM Identification Parameters" if a new flash file is flash programmed into the ECM.

The system configuration parameters are arranged in groups. Refer to Table 1.

Parameter Descriptions

Selected Engine Rating

Rating Number

The "Rating Number" corresponds to the selected set of performance maps for the application. The selected set of performance maps are derived from several unique sets of maps that are resident in the flash file. The dealer and/or the OEM will need to select the appropriate rating tier, if more than one rating tier is present. The rating tiers are A through E.

ECM Identification Parameters

Equipment ID

"Equipment ID" allows the customer to enter a description into the ECM in order to identify the vessel. A maximum of 17 characters may be entered. This parameter is for reference by the customer. Programming this parameter is optional.

Engine Serial Number

Program this parameter to match the engine serial number that is stamped on the engine information plate. This parameter must be programmed if the ECM is replaced.

Note: Always use the engine serial number that is resident in the ECM when you request factory passwords.

Engine/Gear Parameters

Engine Location

Note: The "Number of Synchronized Engines Configuration", "Engine Location", and "Secondary Throttle Enable Status" must be programmed in the following order:

  • Number of Synchronized Engines Configuration

  • Engine Location

  • Secondary Throttle Enable Status

This parameter can be set to one of the following values:

  • Port

  • Starboard

  • Center

  • Engine #X (X is the engine number)

Number of Synchronized Engines Configuration

Note: The "Number of Synchronized Engines Configuration", "Engine Location", and "Secondary Throttle Enable Status" must be programmed in the following order:

  • Number of Synchronized Engines Configuration

  • Engine Location

  • Secondary Throttle Enable Status

Program this parameter to the number of synchronized engines that are used in the application. The allowable range is from 1 to 5. The default value is 1.

If this parameter is programmed for more than one engine, the "Secondary Throttle Enable Status" parameter is automatically set to "Enabled".

FLS (Full Load Setting)

This parameter represents the adjustment to the fuel system that was made at the factory in order to fine tune the fuel system. The correct value for this parameter is stamped on the engine information plate. Factory passwords are required in order to change this parameter.

FTS (Full Torque Setting)

This parameter is similar to "FLS". Factory passwords are required in order to change this parameter.

Compare the values of the FLS and the FTS from the ECM with the values that are listed on the Engine Information Plate. The FLS and the FTS should only be changed after a mechanical change is made to the engine. Entering the wrong values can cause damage to the engine. Entering the wrong values may also void the AVSpare warranty.

Low Idle Speed

This parameter is the engine's minimum allowable operating speed. The allowable range is from 550 to 750 rpm. The default value is 700.

Maximum Trolling Engine Speed

The ECM must limit the engine speed when the engine is in trolling mode. This prevents damage to the clutch. The maximum engine speed is set to the value of this parameter when the engine is in trolling mode. The value of this parameter must be higher than the value of the "Low Idle Speed" parameter.

Secondary Throttle Enable Status

Note: The "Number of Synchronized Engines Configuration", "Engine Location", and "Secondary Throttle Enable Status" must be programmed in the following order:

  • Number of Synchronized Engines Configuration

  • Engine Location

  • Secondary Throttle Enable Status

This parameter can be programmed to "Enabled" or "Disabled". The default value is "Disabled". If the "Number of Synchronized Engines Configuration" parameter is programmed to more than one engine, this parameter is automatically set to "Enabled".

Refer to Troubleshooting, "Engine Synchronize Switch Circuit - Test" for more information on the secondary throttle.

Tachometer Frequency Configuration

This parameter provides for the adjustment of the ECM output for a tachometer. The allowable range is from 12 to 500 pulses per revolution. The default value is 113.

System Operating Voltage Configuration

At the time of this publication, this parameter is not active.

Optional Sensor Parameters

Transmission Oil Temperature Sensor

This parameter can be set to "Installed" or "Not Installed". The default value is "Not Installed". Setting this parameter to "Not Installed" disables fault monitoring of the circuit for the transmission oil temperature sensor.

Transmission Oil Pressure Sensor

This parameter can be set to "Installed" or "Not Installed". The default value is "Not Installed". Setting this parameter to "Not Installed" disables fault monitoring of the circuit for the transmission oil pressure sensor.

Fuel Level Sensor Installation Status

This parameter can be programmed to "Installed" or "Not Installed". If this parameter is programmed to "Installed", the monitoring system can be programmed to alert the operator when the fuel level is low.

Maintenance Parameters

Engine Oil Capacity

Program this parameter to match the actual engine oil capacity in quarts. The allowable range is from 20 to 80. The default value is 30.

Fuel Correction Factor

The Fuel Correction Factor (FCF) fine tunes all of the fuel data that will be stored in the future by the ECM. AVSpare recommends changing the FCF only after an operating interval that allows a comparison of actual fuel economy to the fuel economy that is calculated by the ECM for typical operating conditions. The allowable range is −64 to +63.5. The default value is zero.

Calculating the Error

Error = [(Actual fuel economy − Economy calculated by the ECM) ÷ Actual fuel economy] × 100

Calculating the New Fuel Correction Factor

New FCF = Old FCF + [(100 + Old FCF) × Error] ÷ 100

Note: The old FCF is the FCF that is currently programmed in the ECM.

Maintenance Indicator Mode

The ECM records data that is related to equipment maintenance. The ECM will activate the maintenance indicator lamp when scheduled maintenance is due. The maintenance indicator lamp can be reset by activating the maintenance clear switch or via Cat ET.

The maintenance interval can be based on operating hours or on fuel consumption. This parameter can be set to one of the following values:

  • Off

  • Man Hour

  • Auto Hour

  • Man Fuel

  • Auto Fuel

The default value is "Off".

PM1 Interval

This parameter allows the customer to define the maintenance interval if the "Maintenance Indicator Mode" parameter is programmed to a manual option. Refer to the Operation and Maintenance Manual for additional information on programming this parameter.

Passwords

Customer Password #1

This parameter allows the customer to lock out certain parameters by entering a password. Customer passwords must be used to unlock any parameters that are protected by customer passwords before the parameter can be changed. Factory passwords are required if this password is lost.

Customer Password #2

This parameter allows the customer to lock out certain parameters by entering a password. Customer passwords must be used to unlock any parameters that are protected by customer passwords before the parameter can be changed. Factory passwords are required if this password is lost.
