PROGRAMMING
The Handheld Monitor is the interface to the Atomic LS EFI system, there is no connection for a PC
or laptop. It simply plugs into the Power Module and can be removed once your setup is complete,
or can remain connected so you can use features such as the dash or digital gauge displays.
The Handheld Monitor features a joystick to scroll through the settings. Scroll up and down to the
setting, then push the joy stick to the right to select the options. When the selection is made, either
push in, or simply go back (push to the left) to save/confirm your settings.

ENGINE IDENTIFICATION INFORMATION
GM has produced a number of different LS based engine
platforms. When setting up your Atomic LS system, it is helpful
to know the model engine you have. If you don’t know what
engine you have, locate the casting number on the back of the
block, below the driver's side cylinder head (Figure 17). That
number will assist in determining what engine you have and
can be looked up at www.atomicefi.com.
If you still have no idea of your engine’s origin, you can select a
base calibration from the menu to get the engine started.
MAIN MENU
Six selections will come up the Monitor under the Main Menu.
If this is the first time powering up the Atomic LS, select Initial
Setup (Figure 16).
Atomic LS Dash: This selection allows you to view a variety of
engine functions in real time when the engine is running.
Atomic LS Gauges: This setting puts five important values
in gauge form to ease viewing the data. This includes
engine rpm, oil pressure, engine coolant temperature,
speed (when connected), battery voltage and air/fuel
ratio.

engine.
Advanced Setup: Optional settings for features and optimized
