Help for any parameter in the Mallory SparkMap software, can be ac-
cessed by clicking on the parameter name and pressing F1.
Once you are online with the module the “Comm Rx” light will be
flashing on the main screen, and the information bar at the bottom of
the screen will display “Online, F9” in the lower left hand corner. Go to
the Ignition Configuration Screen (Ctrl-I) and select the Ignition trigger
type from the drop down box and press F10 to send the change to the
Firestorm Module. This will set all parameters on this screen and save
the changes to memory in the Firestorm Module.
Navigate to the Engine Configuration Screen (Ctrl-E) and enable any
sensors you have installed to use as an input to Firestorm. These may
include:
MAP - manifold pressure sensor
TPS - throttle position sensor
ECT - engine coolant temp sensor
IAT- intake air temp sensor
HEGO - wideband a/f ratio sensor
Set rev limits based on your application requirements.
If Firestorm fan control is used, set fan on and off temps based on your
application requirements.
Press “Send all to ECM” to save changes to the Firestorm module.
Press F3 to navigate to the Base ignition advance table. This table is
where ignition timing tuning for maximum performance is done. This
map is pre loaded with values that are a good starting point. Changes
to this table should be made to achieve maximum torque on an engine
/ chassis dyno, or maximum speed on the track without detonation,
and under controlled conditions. If you are not comfortable or familiar
with the tuning process, contact Mallory Technical Service for a recom-
mendation to an authorized Mallory tuning dealer in your area.
TROUBLESHOOTING
This section offers several tests and checks you can perform to ensure
proper installation and operation of the Firestorm Ignition Control
Module. If you experience a problem with your Firestorm, first check
for proper installation and poor connections. You can eliminate many
problems by checking these items. If you have any questions concern-
ing your Firestorm Ignition Control Module contact the MALLORY
Technical Service Department at 216-688-8300 Monday through
Friday, 8:00 am to 5:00 pm Eastern time.
ENGINE RUN-ON
If your engine continues to run even when the ignition is turned off, you
are experiencing engine run-on. Usually, older vehicles with an external
voltage regulator are susceptible to this condition. Because the Ignition
Control Module receives power directly from the battery, it does not
require much current to keep the unit energized. If you are experienc-
ing run-on, it is due to a small amount of voltage going through the
charging lamp indicator and feeding the small red/white wire (even if
the key is turned off).
GM 1973-83 with Delcotron Alternators
GM Delcotron alternators use an internal voltage regulator. Install the
diode inline on the smallest wire exiting the alternator. It is usually a
brown wire.
Most other applications
To eliminate run-on, place a resistor in-line to the small red/white wire
to keep voltage from leaking into the Ignition Control Module.
MISSES AND INTERMITTENT PROBLEMS
Most common causes include a coil or plug wire failure, arcing from
the cap or boot plug to ground or spark ionization inside the cap. Per-
form the following checks:
• Inspect the plug wires at the cap and at the spark plug for a tight
connection. Visually inspect for cuts, abrasions, or burns.
• Inspect the primary coil wire connections. Because the Ignition
Control Module receives a direct 12 volt source from the battery,
there will not be any voltage at the coil positive (+) terminal, even with
the key turned on. WARNING: During cranking, or while the engine
is running, very high voltage will be present and no test equipment
should be connected. WARNING: Do not touch the coil terminals dur-
ing cranking or while the engine is running.
• Make sure that the battery is fully charged and the connections are
clean and tight. If you are not running an alternator, this is an impera-
tive check. If the battery voltage drops below 10 volts during a race,
the Ignition Control Module output voltage will drop.
• Is the engine running lean? Inspect the spark plugs and the entire fuel
system.
• Check all wiring connections for corrosion or damage. Remember to
use proper connections followed by soldering, then seal the connec-
tions completely.
CHECKING FOR SPARK
Triggering the Ignition with the Dark Blue (PTS) Wire
1. Make sure the ignition switch is in the “OFF” position.
2. Remove the coil wire from the distributor cap and set the terminal
approximately 1/4” from ground.
3. Disconnect the Ignition Control Module dark blue wire from the
distributor’s points or ignition amplifier.
4. Turn the ignition to the “ON” position. Do not crank the engine.
5. Tap the dark blue wire to ground several times. Each time you pull
the wire from ground, a spark should jump from the coil wire to ground.
If spark is present, the ignition is working properly.
If Triggering With the Magnetic Pickup:
1. Make sure the ignition switch is in the OFF position.
2. Remove the coil wire from the distributor cap and set the terminal
approximately 1/4” from ground.
3. Disconnect the Ignition Control Module magnetic pickup wires from
the distributor.
4. Turn the ignition to the ON position. Do not crank the engine.
5. With a small jumper wire, short the magnetic pickup + and - wires
together. Each time you break this short, a spark should jump from the
coil wire to ground. If spark is present, the ignition is working properly.
If there is no spark skip to Step 6 below.
6. If there is no spark.
A. Inspect all of the wiring.
B. Substitute another coil and repeat the test. If there is now spark,
the coil is at fault.
C. If there is still no spark, check to make sure there is 12 volts on
the small red/white wire from the Ignition Control Module when the key
is in the ON position. If 12 volts is not present, find another switched
12 volts source and repeat the test.
D. If, after following the test procedures and inspecting all of the
wiring, there is still no spark, the Ignition Control Module is in need of
repair. See the Warranty and Service section for information.
There are three different large cap HEI distributors. To identify which
of the following diagrams fit your specific application, remove the dis-
tributor cap and rotor and locate the ignition module at the base of the
distributor. Count the number of terminals on both ends of the module
and follow the corresponding diagram. GM used 4, 5, and 7-pin mod-
ules in these distributors.
NOTE: Some 5-pin modules may experience a hesitation or stall
on deceleration. If this occurs, contact the MALLORY Technical
Service Department for the required bolt-in diode to correct the
problem.
