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.

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

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.

TRANSMISSION (Shifted Manually)

Automatic transmissions and their shifters are programmed, and
wired, like manual H-Pattern systems, except the retard switches
are connected to the shifter in a straight line.

As you shift gears, the values programmed take effect; each gear
with its own programmed value.

IRING AND PROGRAMMING A LENCO-TYPE SHIFTER

W

here are major differences between the Lenco gearbox and shifter, and an H-Pattern

manually shifted transmission:

• The Lenco box accumulates gear ratios.

Higher gear’s ratios are the total
of the lower gear shifts.

•The Lenco has a stick for each gear.

Before shifting into a high gear, all
lower gears must be engaged.

i.e. To be in

WIRING

GEAR SHIFT SWITCHES

lthough programming may be different for Automatic, H-Pattern, or Lenco type trans-

missions, the way you place and connect their switches will probably be similar.

nfortunately gear shifts come in many different shapes, and we cannot tell you which

ind of switch you should use. You’ll have to choose and attach your own switch.

SOME GUIDELINES FOR

ATTACHING SWITCHES

A momentary or a toggle switch is

•

probably best: one that stays in its
tripped position until the shifter is
put into another gear.

Place your switch so that only the

•

selected gear shift can trip it.
Make sure all switches are firmly

•

fixed in place, and that nothing can
tangle their wires.

WIRING F

Ground the same way
that you Grounded the

2-Pin Connector.

OR NITROUS

Connect the G

REY wire to the Nitrous

system by splicing it to the wire running
between the Nitrous solenoid and the
Nitrous activation switch.

Timing Retard for Nitrous is added on top of whatever Timing Retard is already active.

i.e. You have programmed Top gear to retard timing by 15° with the

rd

3

button, and Nitrous to retard by an additional 5° with the N2O key.

You are in Top gear when your A

CCEL 3-Stage Rev-limiter activates

the Nitrous system. Total Timing Retard instantly becomes 20°.

With Multi-stage Nitrous use any unused switch to sense when the system is activated.
Wire the unused switch to the negative terminal of any Nitrous solenoid. (See Pg 8.)
