Setting Stage2 Boost Level and Ramp Rate
Overview—The Stage2 Programming switches are used to set the target psi when In-
put2 is active. To determine the Ramp Rate of Stage2 see instructions below. When Stage1 is
configured for Launch Mode Input2 activation will be ignored until Input1 is released. See
“Configure Stage1 / Input1 Operating Mode” for more information.
Setting Target Psi—There are two Stage2 target psi programming switches. These
are used together to represent the target psi desired. Example—15psi setting, set Stage2, 10’s
switch to 1 and then 1’s switch to 5. If a setting greater than 40psi is used the AMS-500 will
default to a 40psi setting for this stage. Please see diagram below.

Setting Stage2 Ramp Rate—There are 16 Ramp Rates available for Stage2 boost
control. These are selected using the Stage2 Ramp Rate Select Switch. A setting of 0 will re-
sult in the target pressure being applied immediately when Stage2 is active. See chart below
for other Ramp Rates. The Ramp Rates are defined as psi per second.

Psi per second settings.
0 = Maximum ramp rate.
8 = 8psi per second.
1 = 1psi per second. 9 = 9psi per second.
2 = 2psi per second. A = 15psi per second.
3 = 3psi per second. B = 20psi per second.
4 = 4psi per second. C = 30psi per second.
5 = 5psi per second. D = 40psi per second.
6 = 6psi per second. E = 50psi per second.
7 = 7psi per second. F = 60psi per second.
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!
