INITIAL SETUP PROGRAMMING
Scroll down to Initial Setup and push the joystick to the
right. This takes you to several selections that MUST be
programmed. Figure 18 shows screen examples.
Engine Type: This value determines the engine platform that
you’re running. Select over 26 engine combinations
between LS1, LSA, LY9, etc. There is also a Custom
setting for highly modified or aftermarket engines.
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 you select LQ9, the coil, injector and MAP
sensor will automatically set to the OEM component.
(You can still put in different values if modifications have
been made.)
• Custom: If you have a custom built engine it is
recommended to select the closest Engine Type
setting first. This will give you a start-up calibration
and default settings including the volumetric efficiency
tables for that series of engine. From there, you
can go back into each selection and edit to your
specifications.
Engine Size: Once you select the engine type, the stock cubic
inches will automatically be set. If your engine has been
modified with a different stroke or bore, select and input
the size. The range is from 100-800 cubic inches.
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.
Coils: Once the engine type is selected above, the OEM coil
pack will be automatically selected. However, if you are
running a different coil or an MSD LS Coil pack, select
the part number.
