Map editor: table view & shared tools

The map editor opens one named map and lets you view and edit it in three ways — a Table, a 2D plot or a 3D surface — chosen with the View button. This page covers the tools that are shared by every view and the Table view itself; the plot views each have their own page: the 2D view and the 3D view. Open the editor by double-clicking a map in the collection panel; it works on the active version.

The shared toolbar

These controls sit on the toolbar in every view:

• Map Info (Ctrl+I) — a summary on hover, full details on click; Locate in Map List (Ctrl+L) selects this map in the side panel.
• Raw (Ctrl+R) — toggle raw stored numbers vs scaled physical values.
• Copy — Copy X Axis, Copy Y Axis, Copy Whole Map (with axes), Copy Selection with Axis Headers, Copy Cell Address, and Copy as C Array.
• Modify… — the bulk edit operations (below).
• Heatmap — colour by value (its meaning and stored state differ per view).
• Reference and Diff — compare against another version.
• View — switch to Table, 2D or 3D.

The Table view

The table is the spreadsheet grid: the X and Y axis values run along the edges and the data cells fill the middle. Type a value, press F2 or double-click to edit a cell; an out-of-range value is rejected and the old one kept. The table’s right-click menu carries the shared items plus two of its own: Column Size (preset widths or auto-fit) and, when comparing, Revert Selection to Reference.

The status bar

The bar along the bottom has three segments: a left readout (the active cell’s address and value, plus the reference value and Δ when comparing), a centre with selection stats (count, rows × columns, min/max/average/sum), and a right context segment (the map and units, with a [REF] or [DIFF] tag when comparing).

Editing the map

Select a block of cells and apply a Modify operation:

• Fill, Add / Subtract and Multiply — set, shift or scale the selection.
• Interpolate — a ramp across a row, down a column or 2D (bilinear) across a block.
• Linear Extrapolate — extend an axis with a new value and fill the new cells by projection.
• Smooth averages neighbours; Invert around value flips cells about a pivot; Mirror (horizontal / vertical) and Transpose rearrange the block; Matrix applies an advanced bulk operation.

The six copy formats include Copy as C Array for pasting the data into code. Every edit is undoable on this editor’s own stack.

Warning — editing a map changes the file. Correct the checksum on export, or the ECU may reject the image.

Comparing versions

Pick a Reference version to overlay its data read-only, then turn on Diff to colour the cells by their difference: delta (current − reference), percent change, or highlight changed only. While comparing, Revert Selection to Reference restores chosen cells to the reference values.
