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.
