Setting Input1 and Input2 Activation Polarity
Overview—Input1 and Input2 can be configured for either Ground activation or +12
volt activation. This allow the AMS-500 to be used with existing wiring configurations already
installed.
The Inputs are configured using the 2-position Input Polarity Select DIP switch.
Setting Input1 Polarity—DIP Switch #1 OFF for Ground Activation and Switch #1 ON
for +12 volt activation.
Setting Input2 Polarity—DIP Switch #2 OFF for Ground Activation and Switch #2 ON
for +12 volt activation.
Setting Stage1 Boost Level
Overview—The Stage1 Programming switches are used to set the target psi when In-
put1 is active. This setting will either determine Stage1 target psi or Stage1 Launch psi, see
“Configure Stage1 / Input1 Operating Mode” for more information.
Setting Target Psi—There are two Stage1 target psi programming switches. These
are used together to represent the target psi desired. Example—24psi setting, set Stage1, 10’s
switch to 2 and then 1’s switch to 4. If a setting greater than 40psi is used the AMS-500 will
default to a 40psi setting for this stage. Please see diagram below.

IMPORTANT—The AMS-500 controls the pressure on the Waste Gate so the actual
boost level obtained is a combination of the Waste Gate Spring pressure and pressure
applied by the controller
