Mallory Ignition ACCEL timing retard module 49355 - Manual (Page 7)

.e. Assume you are running a four-
speed Lenco transmission, and
you have programmed your new
A
CCEL Timing Retard Module so
that the 1 st button’s value is 4°, the 2 nd button is 5,° and the 3 rd button is 6°.
Remember: A button’s label refers to its switch, NOT to which gear it is wired.
• Usually you will not be adjusting Timing Retard for First gear.
The A CCEL Timing Retard Module has been designed to adjust
Retard for three forward gears, and for Nitrous (see Pg-11) .
• When you shift into 2 nd gear you will get 4° of Retard,
since the 1 st button has been programmed 4° for 2 nd gear.
• When you shift into 3 rd gear you will have 9° of Retard.
The 1 st button’s 4° is added to the 2 nd button’s 5°,
making a total of 9° when you are in 3 rd .
• Shift into 4 th (Top) gear and you will get 15° of Retard.
1 st and 2 nd values are added to the 3 rd button’s value;
4° + 5° + 6° totals 15° of Retard, for 4 th gear.
s with an H-Pattern or automatic shifter; wire the three
witches to your top three gear positions so that each
ear’s stick, as it is engaged, closes a switch contact.
When in Top gear all three switches will be closed.
ach stick’s switch should have one contact wired
o +12 VDC , and the other contact wired to the Timing
etard Module’s 4-pin flat connector (see Pg 8).
he Timing Retard Module senses when more than
ne switch is closed, and totals the values you have
rogrammed for all lower gear’s shifts.
W IRING AND P ROGRAMMING A L ENCO - TYPE S HIFTER
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 4 th gear, the 3 rd
AND the 2 nd gear sticks
must also be thrown.
• When you are moving forward 1 st is always
engaged. Reverse is triggered off 1 st .
Keep these differences in mind when installing, and
programming, your new A CCEL Timing Retard Module.
