INSTALLATION INSTRUCTIONS
LAUNCH TIMING CURVE
LaunchCurve – (Default - See Graph)
The MC-4 allows you to program a timing curve that is only active when you are
in first gear. When this curve is active the word active appears on the bottom of
this graph. This curve is programmable by the
graphical map.
The easiest way to achieve this is to maximize the
box that contains the Launch Curve. In order to
move the curve you will need to place your mouse
over the portion of the graph that you would like
to move. Right click your mouse and select “Add
Dot”. This will give you a red dot that you will
be able to position anywhere along the curve.
Continue to do this until your curve is completely
mapped out. After this curve has been edited,
save it in the MC-4 with a transfer - Plot to MSD or
File-Save As to save it in a file on the PC.
RUN TIMING CURVE
RunCurve – (Default - See Graph)
The MC-4 gives you the ability to map out a
complete timing curve from 800 rpm all the way
to 15,000 rpm. This timing curve can increase or
decrease at any point along the graph.
The easiest way to achieve this is to maximize the
box that contains the Run Timing Curve. In order to move the curve you will
need to place your mouse over the portion of the graph that you would like to
move. Right click your mouse and select “Add Dot”. This will give you a red
dot that you will be able to position anywhere along
the curve. Continue to do this until your curve is
completely mapped out. After this curve has been
edited, save it in the MC-4 with a transfer - Plot to
MSD or File-Save As to save it in a file on the PC.
Note: Any graph can be printed by selecting
Transfer-Print. Also all other parameters can be
printed from the Data Editor-Select-Print.
RPM ACTIVATED WINDOW SWITCH
RPMSW – (Default - On: 2,000 RPM; Off: 6,000
RPM)
This feature will supply ground to the Purple/Blue
wire when the On rpm value is reached, then it
will remove the ground when the Off rpm value
is reached. This wire will handle a maximum 3
Amp continuous draw.
The options are: ON 2,000 - 15,000 in 100 rpm increments

OFF 2,000 - 15,000 in 100 rpm increments
