7.1.8
Ether Start
Ether start can be set with the programming station only. Requires ECM software level to be
greater than 3.00, and enable output for Ether Start. Refer to Ether Start manual, 7SA727.
7.1.9
Fan Controls
Fan type is set in the mainframe; None; Single; Dual; Two Speed; are the allowed types. The
correct inputs (if any are needed or desired) and outputs must be configured to an available
cavity with the programming station.
Required Outputs: Configure to any output cavity
Fan control #1 for Single
Fan control #1 and Fan control #2 for Dual or Two-Speed types
Inputs are optional: Configure to any input cavity with the programming station
Auxiliary Fan Control
Fan Override

Fuel Economy Incentive
Fuel Economy Incentive (FEI) can be set with the DDR or programming station.
FEI is a DDEC feature that allows vehicle owners to set driver goals of fuel economy while
offering the driver an incentive which is a result of his/her good driving habits. The FEI will
automatically allow a higher vehicle speed (speed increase is dependent on the customer selected
settings) than is set in the road speed limiting area of the ECM. FEI was released with ECM
software level 5.00.
There are four items relative to FEI:
Minimum MPG (MIN MPG)
This would be defined as the customer's minimum fuel economy goal. Any fuel
economy obtained by the driver greater than this figure would result in a allowed
speed increase. Each increase of 0.1 mpg will provide the speed increase dictated by
the Conversion factor (or Scaler MPH/MPG).
Maximum MPH (MAX MPH)
This would be the absolute maximum speed increase to which the customer wants
the vehicle limited. The value is an increase above the vehicle speed limit. The
allowed values are 0 to 20. A value of 0 disables the FEI feature. A value of 1 to 20
enables the FEI feature.
Conversion Factor (Scaler MPH/MPG)
The miles per hour you want to allow for each full mile per gallon above the minimum
mpg. Example: a value of 10 will allow the driver to go 10 mph above the road speed
limit for each full (1) mile per gallon above the minimum mpg. If the minimum mpg
is 7.0, and the driver is getting 7.1 mpg, then the system will allow one additional mile
per hour increase, etc. The unit will still be limited to the maximum MPH.
