OPERATION
The Digital 2-Step Control is designed
specifically for the MSD Digital 6AL
Ignition Control, PN 6425. It provides
the ability to set an rpm limit to be used
during the launch of the vehicle through
a switch or tied into a line-lock device
or trans-brake.
There is a Blue wire coming out of the
2-Step, that controls when the launch
rpm limit is activated. When this wire
is connected to 12 volts, the 2-Step is
activated. When released, the rpm limit
that is set in the Digital 6AL Ignition is
active. This wire can be tied into a trans-
brake circuit, a clutch switch or simply
a stand alone switch.
RPM LIMIT
The rpm limit is set with the two rotary dials, in 100 rpm increments. The limit can be programmed
from 2,000 rpm to 11,800 rpm. (The position for 11,900 is reserved for use with MSD's Power Grid
ignition system.)
LED
There is a useful LED built into the Digital 2-Step. This LED will illuminate when 12 volts are applied to
the Blue wire and the low rpm limit of the 2-Step is active. When 12 volts are removed from the Blue
wire the 2-Step rev limit and the LED will turn off.
3-STEP
If you prefer to have three different rev limits, a second PN 8732 could be used to provide a third rev
limit, such as for use during the burnout.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
