OPERATION

DIGITAL OPERATION

The MSD Programmable Digital-7 Plus uses a high speed RISC microcontroller to control the ignition’s output

while constantly analyzing the various inputs such as supply voltage, trigger signals and rpm. The high speed

controller can make extremely quick compensations to the output voltage, multiple spark series, timing and rpm

limits while maintaining accurate timing signals to within +/- 0.1° and +/- 10 rpm. The circuits and controller of

the ignition have been thoroughly debounced and suppressed to create protection against Electro Magnetic

Interference (EMI).

CAPACITIVE DISCHARGE

The MSD features a capacitive discharge ignition design. The majority of stock ignition systems are inductive ignitions.

In an inductive ignition, the coil must store energy and step up the supplied voltage to maximum strength between

each ﬁring. At higher rpm, since there is less time to charge the coil to full capacity, the secondary voltage falls short

of reaching its maximum energy level which results in a loss of power or top end miss.

The MSD Ignition features a capacitor which is quickly charged to 520 - 535 volts and stores its energy until the

ignition is triggered. With the CD design, the energy sent to the coil is always at maximum power even at high rpm.

MULTIPLE SPARKS

The MSD produces full power multiple sparks for each ﬁring of a plug. The number of multiple sparks that occur

decreases as rpm increases, however the spark series always lasts for 21° of crankshaft rotation. Above 3,300 rpm

there is simply not enough “time” to ﬁre the spark plug more than once, so there is only one powerful spark.
