Item Explanations - Item Explanations provide a brief
description of what the currently selected in the currently
selected Display does, or is used for. So, for example, if the
selected Display was an Options Display, the Item
Explanation would describe the selected Option with that
selected Options Display. For Calibration items (Options
and Tables) this explains how the ECU uses that item to
accomplish a function. For Log items (Channels) this
explains what the value represents to the ECU.
Function Explanations - Function Explanations provide an
in depth explanation of the way Options, Tables and
Channels work together in the ECU to accomplish a
function. Here a function just means anything that the ECU
needs to control. So, for example, firing the fuel injectors is
a function, or controlling a boost control solenoid is a
function. Function explanations are associated with the
selected Display, so selecting a Display is the only way to
change the Function Explanation displayed.
Links - Function Explanations can contain links to the
Calibration and Log items they refer to (Options, Tables,
and Channels). Links are indicated with blue underlined
text, just as the standard hyperlinks in a web browser are.
When the user clicks on a link the item (either Calibration or
Log) the link references will be added to the appropriate
Display on the current Display Sheet and selected, giving it
focus. If that item already exists in a Display on the current
Display Sheet, then the item will just be selected. So, for
example, if the user clicks a link representing the "WG
Base Duty” map (as seen in example of the left) the 3D
Map Display containing that table would be opened (unless
it already existed on the Sheet) and that Display would
become selected.
Option links are treated differently from Table and Channel
links. Instead of just displaying the name of the Option in
the link, its current value from the loaded Calibration is
used, to provide an even more meaningful description of
how your particular car is setup. So if a link is simply a
number, it is an Option link. It can still be clicked just as
Table and Channel links are, and the referenced Option will
be displayed and selected.
