The “Starting” drop-down selections allow the user to calibrate parameters associated with
starting (cranking) and running the engine for a short period of time (temperature dependent)
after the engine is initially started.
To configure engine starting fuel, go to Starting on the Tool Bar. Left click on “Starting” and a
drop down screen will open. Keep the left mouse button depressed and slide the mouse pointer
down until the desired “Starting” fuel drop down is highlighted.
The BigComm software allows the user to configure the Load (MAP)
and RPM axes allowing for a larger number of cells (map area) to be
used for the fuel and spark tables.
