The MSD Programmable Launch Boost Controller allows you to program a boost pressure map
from the launch through a complete run from 12.5 to 100 seconds. You can also program a boost
limit during the burnout. The boost pressure is controlled through two PWM outputs that control
two normally closed 2-way, solenoid valves connected to the waste gate actuator. The actuator is
programmed through PID servo-control and can be tuned for the particular actuator response.
The Boost Controller also can record from 20 to 160 seconds of data including engine rpm, map
pressure, Boost Curve Pressure, Barometric Pressure, PWM output and the Launch and Overboost
input wires. This can all be saved and reviewed in the Launch History window of the MSD software.
All of the programming features can be set with the MSD Pro-Data+ software. This software is for
PCs running Windows 95, 98, 2000, NT, XP or ME. All of the parameters can be saved in the PC,
then uploaded to the Controller. There is also a Hand Held Programmer/Monitor, PN 7550, that is
available separately. This unit has an LCD display that will walk through the programming menus
for programming without a PC.
PROGRAMMABLE FEATURES
BURNOUT
This determines how the Light Blue Burnout wire is activated. It can either be activated by applying
12 volts or by switching it to ground.
Default is 12 volts.
SwPWR
12 volts activation
SwGND
Ground activation
BOOST
Program a boost map based on time from 12.5, 25, 50 or 100 seconds. Also, select a maximum
boost pressure for the burnout.
Launch: This is the map for the run. This program is made on the Boost Pressure Curve
graph. The Boost pressure can be plotted over time down to 0.01-second and 0.1-psia
increments. One to thirty-two points may be set in the graph.
Burnout: Select a maximum boost pressure that will be used during the burnout. Adjustable
from 0 - 75-psia.
Overboost: This selection lets you program a rampable boost value that is higher than the
programmed curve. Overboost is only activated when its activation wire (Orange) is switched
to 12 volts.
Max: This adjustment extends the time that you can program a boost curve. Adjustable in
12.5, 25, 50 or 100 seconds.
