Why use the 3D view?
A table of numbers hides shape. A 3D surface shows it. Steps, spikes and dips that you would scroll past in a grid jump out when the table is drawn as a landscape. We use the 3D view to sanity-check fuel and ignition maps after a session of cell-by-cell tuning, and to check that interpolated areas actually blend into the tuned areas around them.
It works on whichever tuning table you have selected. If you prefer to work with numbers, the 2D view and text view show the same data in other forms.
Moving around and editing
| Action | How |
|---|---|
| Move between cells | Arrow keys |
| Raise or lower the selected cell | Page Up / Page Down |
| Rotate the surface | Click and drag with the left mouse button |
| Return to the standard angle | The reset angle button, top right of the display |
Reading the display
- Selected cell: shown highlighted in blue. Its value appears on the left.
- Engine position: a blue arrow marks where the engine is running on the table right now, so you can see which cells are in use as you drive or run the dyno.
- Selection size: shown in the top right corner.
- Output Value: bottom right. This is what this table alone is producing at the current operating point.
The Output Value only reflects this table. Correction tables, such as temperature or other compensations, can change the number the ECU ends up using. If the final value in your log doesn't match the Output Value, look at the corrections before changing the base table.
How we use it
- Tune steady-state cells in the grid, where you can see exact numbers.
- Switch to 3D and rotate the surface to look along each axis for steps or spikes.
- Fix anything that stands out, then confirm on the dyno or in logs.
