Add Curve
To add a new profile curve, select the "Add" button and a
Create Curve keyboard screen is displayed (Fig. 113). Enter a
name; use only alpha-numeric characters for the new curve
and then touch the "OK" button. If other characters are used, a
pop-up box will appear informing user that an invalid character
has been used in the curve name.

Select the "new curve" name from the Curves list on the
"Offline Profile Curve Builder. Then select the "Edit Curve"
button. (See Fig. 115.)
• Select the point type from type list (Point; Light Off; Purge;
Minimum; Maximum).
• Select the Air% text box and adjust the open percentage for
the air actuator (Fig. 118 and Fig. 119).

• Select the Fuel% text box and adjust the open percentage
for the fuel actuator.
• Select the FGR% text box and adjust the open percentage
for the FGR actuator (if applicable).
• Select the "Add Point" button.
As each point is created, the point is added to the list box on
the left side of the screen. Up to 24 points can be added to the
curve. To edit or delete a point, select the point in the list box,
and the right side of the screen updates with the settings of
that point. Change any of these settings and select the "Save
Point" button to accept the changes or select the "Delete Point"
button to remove the point from the profile curve (the list box on
the left side of the screen updates itself with the new settings).
NOTE: To create a profile curve with no FGR, enter zero
for all FGR values when adding/changing points.
Attempting to load a profile curve that has FGR
actuator points into an R7999 that does not have
an FGR actuator will result in loading just the
Fuel/Air curve. Attempting to load a profile curve
that has no FGR actuator points into an R7999
that has an FGR actuator will result in no points
being loaded or a curve with the FGR line flat on
the bottom of the graph.
To save the new curve to the S7999D flash, select the "Save"
button. The profile curve can be viewed graphically while it is
being built as well as later after the curve has been built and
saved. Touch the "View Curve" button to graphically view the
curve (Fig. 117). Use the "page back" arrow to exit the Curve
View screen.
NOTE: Prior to saving the curve, the points are validated
for some obvious errors before allowing the curve
to be saved. If any errors exist, a dialog box dis-
plays with the type of error. The user must correct
the error before the curve will be saved.
To not save the curve, the "page back" arrow can be selected.
A "Curve Changed" popup dialog box will appear; touching the
"No" button will cause none of the user input to be saved.
Control returns back to the primary page for Offline Curve
Building (Fig. 112) after the "Save Curve" and then the "page
back" arrow or "No" buttons are selected.
