The map above shows the fuel requirements for the engine across the load range at
2500rpm. The yellow bar shows that the engine requires 6.51ms of fuel at 52.87kPa and
2500rpm (This is displayed in the top left corner of the screen as selected data). At the top
right corner of the screen, the actual engine data is shown, ie what the engine is currently
running.

The Ignition Maps work in a similar way, except that it is the ignition advance that is stored
in the map instead of the injection time.

The programming software presents the maps in a bar graph formation to make it easy to
visualise fuelling and ignition. Numeric mode can also be selected through the maps menu.

Some of the fuel maps have “Hot-Keys” which eliminate the need to navigate the menu
structure to access the maps. Refer to 3.2 Online and Offline Operation, p24

4.4 What is Mapping the Engine?


“Mapping the engine” is the process of modifying the maps to suit the requirements for your
engine by adjusting the heights of the bars within the maps. Bars may be adjusted one at a
time, or in groups. The Haltech programming software has been designed to make engine
mapping simple and intuitive.
