Precise ignition timing is essential to produce maximum horsepower.
However, one timing setting is not ideal for an engine’s entire rpm range.
The dynamics of air and fuel flow into the engine as well as the speed that
the piston travels through the combustion stroke all affect the ideal timing
setting. Fortunately, the Programmable MSD Ignition lets you tune in a
custom timing curve to match your engine’s requirements.
There are three settings that you program to create a timing curve. First you
set where you want the initial timing, or idle timing. Next you set the rpm
1-REV CONTROL
The MSD’s adjustable rev limiter allows you to
program an rpm limit that the engine will not rev
past. This is a great feature that will save your
engine from over rev damage caused by parts
failure or if the craft’s drive mechanism comes
out of the water. When your limit is reached, the
ignitions adjusts the spark output quickly to stay
below the rpm. This produces a smooth rev
limiting action.
point to begin the curve, followed by the amount you want it to retard
(up to 30°) through the high rpm limit. All the adjustments are made with
dip switches built into the ignition.
This Ignition delivers a powerful capacitive discharge spark from idle to top
end. This improved output results in complete combustion for performance
through the entire rpm range of your engine.
2-HOLESHOT
Thanks to the rev limiting circuit of the Ignition,
MSD engineers developed a feature that will give
you great holeshots. By installing a handlebar
operated switch, you can activate a lower rpm
limit that will hold an engine under 3,000 rpm.
This way you can hold the throttle wide open
and concentrate on the rubberband snapping.
When it does, you release the button, the engine
revs to full power and you launch out in front!
(See page 107. Hole shot control switch)
3-EASY STARTS
When you increase the compression ratio of your
engine, it also puts more presume on your starter
to crank the engine over. The MSD Programmable
Ignition has two features that can help ease cranking
pressure and improve the start up of our watercraft.
Retard:
When activated, this feature retards the
timing 20° to ease cranking. When the engine
starts, the timing returns to the initial setting.
Delay for Electric Starters:
When activated, this
mode will not produce a spark for the first several
rotations of the engine. This helps build momentum
in the engine, resulting in easier starting.
One of the advantages of the MSD Multi-Channel Ignition system is the
individual trigger pickups for each cylinder. This way you can make up for the
variations in fuel flow dynamics to each cylinder, exhaust characteristics or
carb synchronization by altering the timing of each cylinder,
