4.5 Navigating the Map

For all maps whether single or multi ranged navigating the map is done in the same way
(with multi-ranged maps the same navigation between ranges is the same as choosing
another map.) Once a map is displayed on the screen by following the instructions above

the bar heights can be adjusted to adjust the fuel delivered.

The height of the Bars is adjusted by using the up and down arrows keys, the PgUp and
PgDn keys (

) or a combination of these keys with the Shift and Ctrl keys. Increasing

or decreasing the height of the bars increases or decreases the amount of fuel contributed to
the total fuel by that bar of the displayed map. (See the command summary at the end of

this section for a full list of key functions Refer 4.7 Command Summary for Maps, 40).
The active bar (the bar that is affected by the up and down cursors) is highlighted on the
computer screen to distinguish it from the remaining bars in the map. To change the active
bar, use the left and right arrow keys (

). The Haltech software ahs a number of time

saving functions programmed to make mapping the engine simpler.

Note: When two keys are displayed together, such as

, this means that

the second key must be pressed while the first key is held down. In this case,

the

key would be held down while the

key is pressed.

4.5.1 Current Location

Pressing

will take you to the range at which the engine is running, and highlight the bar

that is currently being used. This bar is easily identified by an arrow directly above it
pointing down. As the engine speed and load changes, the arrow moves with it. The Home
key is useful for finding the engine's operation point very quickly.

4.5.2 All Ranges

Across the ranges, the curve of the fuel map does not change greatly. Usually the shape

remains much the same, and the height changes according to the volumetric efficiency of the
engine. In order for all the fuel ranges to initially be set up quickly, the Haltech F10 system
allows you to program all rpm ranges simultaneously with the same data.

turns All

Ranges on, and the words All Ranges appears under the title.
When the All Ranges function is active, a bar adjusted on one graph is copied to the same bar
on all the ranges. If you use this option, you can set the shape of the map at any range, and all

other ranges will be identical at every bar you adjusted. This feature enables all graphs to be
given an initial shape that should run the engine, albeit rather roughly. Once you have used
the All Ranges option for a starting point, press

once more to exit the All Ranges

option and tailor each map individually.

This option is only available on the Base Fuel and Ignition M aps.
