Upper Position Limit
This is the maximum throttle percentage that will be
interpreted by the ECM as full throttle. This parameter
is used with the value of the initial upper position limit
to make an allowance for manufacturing tolerances
between different pedals.

Initial Lower Position Limit
This is the maximum throttle percentage that will
be interpreted by the ECM as zero throttle. This
parameter is used with the value of the lower
position limit to make an allowance for manufacturing
tolerances between different pedals.

Initial Upper Position Limit
This is the minimum throttle percentage that will be

Lower Dead Zone
This is a throttle range above the initial lower position

Upper Dead Zone
This is a throttle range that is below the initial upper

Multiposition Switch Setup

The multi-position throttle switch is an optional
throttle input. A maximum of four switches can be
used. Four switches will allow a maximum of 16
speeds to be selected.
When the multi-position switch is selected as the
"Throttle Type" on the "Throttle Configuration Screen"
of the electronic service tool, additional information
is required.
Number of Switch Inputs
This parameter is the total number of switches that
will be used. The switches may be individual switches
or a ganged rotary switch.

Physical Position
This parameter is non-programmable. The parameter
is used to signify the position of the rotary switch.
Input 4, Input 3, Input 2, Input 1
The number of these non-programmable parameters
that are visible depends on the value that is
programmed into the "Number of Switch Inputs"
parameter. "Open" signifies that the switch is in the
OFF position. "Ground" signifies that the switch is
in the ON position.
Physical Position Enabled
If "Yes" is selected from the drop-down menu, the
Electronic Control Module (ECM) sets the engine
rpm to the value that is programmed into the "Engine
Speed" for the configuration of the switches that is
defined for that Physical Position.
