AMS-500 Boost Controller
Overview
The AMS-500 Boost Controller can control 2-Stages and/or levels of boost. The 2-
Stages are controlled by Input1 and Input2. Both of these inputs can be configured using a DIP
Switch for either Ground or +12 volt activation. Input1 may be configured to function as a
“Launch” stage when used in conjunction with Input2. Input2 offers an adjustable ramp rate as
well as boost level settings.
Each stage has a range of adjustment from 0 to 40psi with 1psi resolution and is con-
trolled to within .1psi to target using advanced control algorithms. If a setting greater than
40psi is configured the AMS-500 will default to the maximum 40psi allowed. A setting of 0psi
will turn either stage off.
An optional Safe Mode is available when using a pressure source other than the mani-
fold pressure. The Safe Mode continually checks for the proper pressure increase and will dis-
able the system and open the decrease solenoid in the event of an error condition. When in
Normal Mode of operation the AMS-500 will keep trying to apply pressure to the waste gate
until its target is reached.
For more information on each individual option see the appropriate section listed in the
Table of Contents on Page 2.
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.

NOTE—The AMS-500 Must be turned OFF and back ON when a change is made to any
switch. If this is not done the new switch settings will be ignored until the next power
on!
