HANDHELD DISPLAY OPTIONS
Display Setup: The display Setup controls the look of the
handheld unit and the Firmware version. The Atomic
LS can be reset to factory default in this section as well
(Figure 34).
LCD Contrast: Adjust the contrast on the LCD screen if it is
hard to see the display. Contrast is adjusted using the
joystick to go up or down in five percentage increments.
Backlight Level: The brightness of the screen is determined
by this setting. The Backlight Level may need to be
adjusted depending on outside light levels. Brightness
is adjusted using the joystick to go up or down in five
percentage increments (Figure 34).
Display Units: The Atomic can display items in either English (cubic inches, Fahrenheit) or Metric
(liters, Celsius). Set Atomic Defaults: Use this feature to reset the Atomic EFI. Selecting “YES”
on this screen will take all setting, including fuel maps, back to the factory defaults. This can
be done when installing the Atomic on a different engine, or for troubleshooting reasons
(Figure 34).
User Mode: This setting can be changed from Basic to Advanced. When the User Mode setting is
changed to Advance the fuel injector selection menu, coil selection menu, and the MAP sensor
menu will open up to all the combinations preprogrammed into the Atomic LS system. The
fuel injector flow rate and MAP sensor Slope and Offset can be manually entered by selecting
user defined in the selection menu (Figure 34).
Set Atomic Defaults: This setting resets all the programming parameters to the default settings out
of the box (Figure 34).
Firmware Versions: The Atomic Firmware version can be found in this section (Figure 34).
PRE-START CHECK LIST
Before attempting to start the motor, run through the pre-start check list to ensure a safe and successful
start.
• Double-check all wiring
• Power and ground leads are connected directly to the battery.
• Red (Pin G) should be connected to a 12v ignition source that is hot in the RUN and START positions
of the key cycle.
• All wiring, modules, and fuel components are mounted away from heat sources such as exhaust
and pinch points.
• Wideband O2 sensor is installed and plugged into the Power Module
• There are no exhaust leaks.
• The throttle linkage is connected and moves freely with no binding.
• The initial programming has been set in the handheld menu.
• Key on the ignition a few times to prime the fuel pump. The fuel pressure may need to be adjusted
to 58-60psi. Fuel pressure can be monitored in the Atomic Dash section of the handheld menu.
• With the fuel system under pressure from priming the system, check for leaks or fuel spraying. Do
not attempt to start the engine if fuel leaks are present.
• Monitor Engine RPM in the Atomic Dash in the handheld unit as the engine is cranked over to
ensure the crank sensor is providing an RPM signal.
