Speed Reference Setting
Enable or Disable Nitrous
Figure 33
Nitrous: This setting enables the nitrous timing retard in the
Ignition timing and the nitrous AFR in AF Target setting.
The default setting is DISABLED (Figure 33).
Calibrate Speed: If there is speed output on the transmission,
a reference signal can be delivered to the Atomic
LS. On manual transmission equipped vehicles, the
Calibrate Speed option improves drivability when
transitioning from high RPM conditions to an idle
(such as comming off of a hill / between moving and
coming to a complete stop). The Power Module has
a Brown (Pin D) wire and a Light Blue (Pin E) wire.
These wires connect to a magnetic pickup monitoring
driveshaft speed with a collar mounted on a yoke. To
program the calibration, drive to 40mph on an open
road to maintain speed. Once at 40mph, select YES
on the handheld. This will calibrate the speed input.
This option will also enable a speedometer reading in
the handheld Atomic LS Dash (Figure 33).
Note: Use of a minimum four magnet collar is
recommended with this option.
Racepak Dash: This setting allows the Atomic LS Truck kit to
interface with a Racepak dash such an IQ3. Disable is
the default setting. Racepak offers an optional V-net
sensor to connect their dash to the MSD Can-Bus
connector (Figure 33).
