When the brakes are applied at the end of a pass, the Light Blue wire is again activated, which
stops the recording process of the Controller.
Do Not activate the Dark Blue wire until the acquisition
files have been downloaded. Doing so will reset and erase the previous run.
Note: The record function can be set for rpm to allow the record to begin at a programmed rpm.
(The Launch wire must be connected to 12 volts.)
Clutch Cars: For clutch car, the Light Blue wire should be connected to a momentary switch to
use the Burnout Boost and to arm the acquisition. The Dark Blue wire for the launch can go to the
clutch or brake switch to activate the boost map and acquisition when the car launches.
ACQUISITION
The Programmable Launch Boost Control can provide you with 20, 40, 80 or 160 seconds of
Controller data during each pass with 2 seconds leading to the launch. Samples are taken by the
microprocessor every 10, 20, 40 or 80-milliseconds. (This number can be averaged in the Analysis
Box by choosing Average.) After a pass, you can recall a variety of parameters to view as they
occurred during the pass including engine rpm, MAP, boost pressure, PWM output and the status
of the Launch and Overboost input wires. After each pass, the file can be saved so it can be stored
and reviewed with other runs.
With the laptop connected to the Controller after a pass, turn the ignition On and go to the Launch
History window. Click on the Transfer pull down menu then select Acq to Plot. This brings the
recorded information to the screen where it can be saved to the PC by clicking File, then Save As.
Note that the numbers on the left side of the screen are arbitrary and there to provide a division
between the spaces. The numbers that go across the top of the chart are seconds and begin at
two seconds prior to the launch.
After saving the file, it can only be opened and viewed in the History File 1-4 screen (there are four).
If this screen is not up, go to the View pull down menu on the Graph View chart and select History
File. Up to 32 data traces can be viewed in one trace box in a file window. Data traces can be
dragged from the Trace box to the Analysis box to view the data with averaging offsets for PSIG
and other functions.
There will be a window available in each Launch History screen; a combination History Analyze
and History Traces window. (If they are not there when you open the History chart, go to View and
select Trace/Analysis box.) There is a third window available called Notes that allow you to write
any important notes to that specific run. The MSD records all of the possible information then you
decide which ones you want to view and compare. This is done by grabbing each title by clicking,
and then dragging it under the Analyze title. After you select the desired traces you can select
Clear to delete the other traces to make room for other traces to compare.
TRACE /ANALYSIS BOX
This box allows you to select the traces that you want to view. The Trace section shows the different
traces you can monitor. The Analysis section allows you to pick and choose which traces you
want to place on the History Analyze graph. The entire list of items can be copied by clicking Copy
at the top of the window, or you can click-and-drag the traces you want from the Trace list to the
Analyze list. The order of the Traces can be changed by clicking and dragging each one to meet
your desired order. You can select the value that it represents or is measured in, its color on the
screen and when it appears. You can also open other acquisition files and bring their traces into
the same History Analyze graph to compare. Up to 64 traces can be shown on the graph, with 32
from the Analyze list and another 32 from the Trace list.
