Breakpoint Spacing Display and Deleting Breakpoints

The Breakpoint Spacing display shows

To move breakpoints, click and drag.

Locking Breakpoints in the Breakpoint Spacing Display

You might want to lock a breakpoint when you are satisfied with its value.

To lock a breakpoint in the Breakpoint Spacing display, right-click a breakpoint and select Lock Breakpoint from the menu.

Locked breakpoints are colored black.

Deleting Breakpoints

Deleting breakpoints removes them from the normalizer table. There are still table values for the deleted breakpoints: CAGE determines the positions of the deleted breakpoints by spacing them linearly by interpolation between the nondeleted breakpoints.

Deleting breakpoints frees ECU memory. For example, a speed normalizer runs from 500 to 5500 rpm. Six breakpoints are spaced evenly over the range of speed, that is, at 500, 1500, 2500, 3500, 4500, and 5500 rpm. If you delete all the breakpoints except the endpoints, 500 and 5500 rpm, you reduce the amount stored in the ECU memory. The ECU calculates where to place the breakpoints by linearly spacing the breakpoints between the 500 rpm breakpoint and the 5500 rpm breakpoint.

To delete a breakpoint, right-click the breakpoint and select Delete Breakpoint.

Deleted breakpoints are green in the Breakpoint Spacing display.

Show the Model's Curvature

You might want to view the curvature of the model to manually move breakpoints to where the model's curvature is greatest.

To display the model slice as its second-order derivative, the curvature of the model:

  1. Right-click the model in the Breakpoint Spacing display.
  2. Select Display -> Model Curvature.

You can revert to displaying the model by selecting Display -> Model from the right-click menu.

Multiple Slice View

By default the Breakpoint Spacing display shows one slice through the model.

Viewing many slices of the model gives a better impression of the curvature of the model. For example, see the following figure.

To view multiple slices through the model:

  1. Right-click the model slice in the Breakpoint Spacing display.
  2. From the menu, select Number of Lines and choose the number of slices that you want to view from the list.
