The “Ignition Map” is used to Retard Ignition Timing. The load input for the
“Ignition Map” is based on MAP, MAF, or TPS. Timing will be removed from the engine
based on the selected load input and engine speed. Since timing can only be removed
(retarded) from the engine, the
“Ignition Map” only accepts negative numbers. For
example, a value of –4 will retard the timing 4°. The load input for the “Ignition Map” is
selected from the “Setup” window. Go to Setup>System and the “Setup” window will
appear. In the
“Ignition” section, select the desired load input from the drop down menu.
Similar to the “Fuel Map”, the F/IC software will also create a base “Ignition Map”.
Right click on the
“Ignition Map” and select “Create base ignition map”. Enter the
“Maximum RPM”, “Maximum boost” (must be absolute pressure), the desired “Timing
retard per unit of
Boost”, and click OK. (Note: As with the “Fuel Map”, final tuning is
required after using the “Create base ignition map” function.)
