Mallory Ignition 49355 User Manual
Congratulations! You have purchased the ACCEL TIMING RETARD MODULE.
This unit can be programmed to automatically retard your engine’s ignition timing
or four different inputs. When not being programmed, your ACCEL TIMING RETARD
MODULE functions as a digital retard meter.
CCEL 300+ RACE WIRE spark plug wires!
Use A
Solid-core spark plug wires emit RFI and EMI static,
which can disrupt On-board electronics.
Do not use your TIMING RETARD MODULE
with another timing control module.
They both may try to override each other.
Do not use your TIMING RETARD
MODULE
with more than 18 volts.
Your ACCEL TIMING RETARD MODULE, like
any electronic component, is sensitive to heat.
Keep it away from temperatures greater than 150°F (65°C)
.
Follow the installation instructions in this Owners Manual carefully.
Incorrect installation may damage your engine, this unit,
and may
VOID YOUR WARRANTY.

nputs to activate timing retard values.
he four inputs may be connected to any

Make sure that its chosen rev-limit fits your engine’s needs and
the needs of any additional control modules.
PRECAUTIONS AND
W
ARNINGS
The ACCEL Timing Retard Module will cause a small, fixed timing retard in the trigger.
This is due to computational delay. Engine ignition timing must be checked, and
re-adjusted, to account for this delay after your timing retard module is installed.
This flexible product makes it easy to select values that can damage your engine.
Start by selecting safe values. Carefully evaluate their effect. Make small changes,
when changing values, and use caution.
MODES OF OPERATION
our new A
CCEL TIMING RETARD MODULE
has three different modes of operation.
1. Programming Programming and Control modes overlap in the sense
2. Control
that timing control is still performed in Programming Mode.
In Programming Mode the display shows the value you are
in the process of programming. In Control mode the LED’s display the
current timing retard from the trigger input.
3. Diagnostics Mode – See Pg. 12.
THE SAVE BUTTON
Pressing the SAVE button tells the Timing Retard Module to store all the values that
have been adjusted. They will be remembered until they have been re-programmed
and over-written with the SAVE button. Turning off the module does not erase any
values that have been stored with the SAVE button.
You can adjust, and test, different settings, without storing values, by turning your
Module off, before pressing SAVE. The unit remembers the last values stored with
he SAVE button, and restores them the next time it is used.
CAUTION: It may take a few seconds for the Timing Retard Module to SAVE values.
Be sure the display shows the current timing retard (default display) before turning
the module off. Powering off during a SAVE may cause you to lose stored values.
After you have completed the wiring (according to diagrams detailed later in this
ocument) you must do some basic configuration of your A
CCEL TimingRetard Module.
1. With the unit powered off press, and hold
down, both the SAVE and CRANK buttons.
2. While holding those two buttons down, apply power to the module.
The module will enter its Programming Mode and display a number that
represents the number of cylinders in an engine (the factory default).
3. Use the ⇑and ⇓keys to select the number of cylinders for YOUR engine.
4. When finished, press SAVE. This stores this new information and puts
the module back into Control Mode operation.
Make this selection only once per installation.
If you do not make this selection your
TimingRetard Module uses the factory default.

ETARD VALUES
Enter Programming Mode by pressing the key for the function you wish to modify.
Adjust the timing retard of that function to an appropriate value.
Exit Programming Mode by pressing that same key again.
i.e. To select a timing retard for starting your engine press the
CRANK button.
The display shows its current value and The Programming Dot will start to flash.
Use the ⇑and ⇓keys to adjust (in 1° increments) the value displayed.
When finished press
CRANK again.
The Programming Dot stops flashing and the current timing retard displays.
Do the same for all timing retard inputs. It is not necessary to exit Programming
Mode to select a new function, simply press the next value’s key.
i.e. Press 1

and select its value. Then press 2ndand select its value.

Since 2
was the last value you programmed, you
exit Programming Mode by pressing 2

again.
When you have finished programming press SAVE to store all new values.
IMPORTANT PROGRAMMING DETAILS
The initial values you program and save into your Timing Retard Module will get you
started. You will eventually want to modify them. Just select a function and change it.
Modifications take effect immediately. Press that function’s key again (displaying current timing retard), and the newly selected value takes effect.
