Analog Input Switch
The AEM EMS can turn a 0-5V input into a switched input. This allows you to configure any
analog channel with a switching point to activate. The is commonly used with shift retard with a
0-5V strain gauge. However, the analog input switch can be used for many other purposes. The
analog input (Switch #7) works by setting a high and low voltage range with a throttle and
engine speed threshold. When the input exceeds the range of the selected voltage and the
other conditions are met, the switch will turn ON/OFF. If a shift cut/retard is to be used with
Switch #7, see the Shift Cut/Retard section.
User Definable Options for Switch #7
Switch 7 Analog In
Units: Analog Input Description: User selectable analog input which is used to make a switched
input.Typically used with shift retard function.
Switch 7 On Above
Units: Volts Description: Voltage threshold above which the Switch #7 will be active. Should be
set higher than Switch #7 On Below.
Switch 7 On Below
Units: Volts Description: Voltage threshold below which the Switch #7 will be active. Should be
set lower than Switch #7 On Above.
Switch 7 Min RPM
Units: Engine Speed Description: Speed threshold that you must be above for the Switch #7
function to be met.
