CUSTOM 1: This tab contains two sub tabs with plots that are similar to MSD PN6010/

PN6012 ignition controllers. The “Engine Speed” tab is similar to springs and weights that

the advance curve as a normal distributor would. The “MAP” table represents a vacuum

advance canister as well as a boost retard. Under a vacuum, it should advance the timing

(positive values) and under boost it should retard values (negative numbers).

CUSTOM 2-4: These tabs are standard 3-D timing tables. The ignition timing will corre-

spond to the value in the cell (the applicable cell being defined by RPM and engine load).

TRUCK: This tab is a timing table to be used on 4.8, 5.3 and 6.0L motors with low octane

fuel.

LS1: This tab is a timing table to be used on a LS1 with low octane fuel.

LS2-3-6-7: This tab is a timing table to be used on a LS2-3-6-7 or 6.2L truck motor with low
