MSD 6214 Midget DIS-2 Programmable Race Ignition Installation - Manual

GENERAL INFORMATION
DIGITAL OPERATION
The Programmable Midget Ignition 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
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 sup-
pressed to create protection against Electro Magnetic Interference (EMI).
Note: This Ignition can be removed from power and still retain its programmed settings.
CAPACITIVE DISCHARGE
The Midget Ignition features a capacitive discharge ignition design. The majority of stock
and aftermarket 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 a top end miss.
The Midget Ignition features a capacitor which is quickly charged to 490 - 505 volts and
stores this energy until the ignition is triggered. With the CD design, the voltage sent to the
coil is always at maximum power even at high rpm.

The MSD Programmable Midget Ignition is a distributorless ignition system (DIS). It provides
powerful capacitive discharge sparks for complete combustion while providing a variety of
rpm and timing tuning programs. It consists of an Ignition Control, 2-Channel Coil Pack, and
incorporates a waste spark firing design. This means that two cylinders are fired at the same
time, one on the compression stroke and the other on the exhaust stroke. Two magnetic
pickups are used for trigger inputs and two outputs go to the supplied coil pack. The com-
ponents offer a direct plug-in wiring harness with sealed, locking Deutsch Connectors. A 12
volt battery is required.
The MSD Programmable Midget Ignition Control requires a crank trigger system. MSD sup-
plies two Non-Magnetic Pickups, but due to the variety of engines and applications, a crank
trigger wheel is not offered. Information is supplied on fabricating a crank trigger wheel.
Note: The Midget Ignition must be used on engines equipped with a battery.
