INITIAL SETUP PROGRAMMING
Scroll down to Initial Setup and push the joystick to the right.
The following parameters must be programmed.
Engine Type: This value determines the engine platform (Figure
29). There are over 26 engine combinations to select
from. This setting is important as once an engine type
is programmed, other settings will default to the OEM
components that were supplied on that engine.For
example, if LQ4 is selected, the coil, injector and MAP
sensor will automatically set to the OEM components.
Engine Size: Once the engine type has been selected, the
stock cubic inches will automatically be set. If the engine
has been modified with a different stroke or bore, select
and input the size. The range is from 100-800 cubic
inches (Figure 29).
Camshaft Type: There are three cam selections to choose;
Street/Stock, Mild and Performance. Note that if the
lobe separation angle (LSA) is less than 108°, it is
recommended to input the next larger cam. Cams with
over 250° are not recommended for use with the Atomic
LS system (Figure 29).

Coils: Once the engine type is selected, the OEM coil pack
will be automatically loaded in the default calibration
file. If a different coil or an MSD LS Coil pack is used,
change the setting to the correct coil type (Figure 29).
Note: There is a setting in Display Setup labeled User Mode.
When User Mode is changed from Basic to Advanced,
the coil selection menu will open up to all the coil
combinations preprogrammed into the Atomic LS
system.
