Nudging values up and down
With cells selected, Page Up raises them and Page Down lowers them by the table's normal step. Hold Ctrl at the same time for a finer step, or Shift for a coarser one. Stepping is the method we use most while the engine is running, because each press is a small, predictable change you can watch on the wideband or in the logs.
Typing a value directly
If you already know the number you want, just start typing. ESP opens an entry box that also shows the range of values the table accepts, so you know the limits before you commit. This is the fastest way to set a single cell or fill a block with the same value.
Changing by a percentage
Press P to scale the selection by a percentage, either up or down. This is the right tool when a whole area is off by roughly the same proportion. For example, if logs show a region of the fuel table running about 5% lean, select it and add 5%. Every cell keeps its relationship to its neighbors, which a flat step wouldn't do.
Linearizing a range
Select three or more cells and press L. ESP keeps the first and last cells and redraws everything in between as an even straight-line transition. It works in the 2D, 3D and Text View displays. We use it to clean up lumpy areas after tuning the end points, and to fill in cells the engine rarely reaches.
Copying cells
- Copy and paste:
Ctrl+CandCtrl+Vwork as in any Windows program. You can paste into a different table as long as the selection is the same size and the data type matches. - Quick copy: hold
Ctrl+Shiftand press an arrow key to copy values into the next cells in that direction. It only works when the selection is a single row or column wide, so 1 × 4 or 4 × 1 is fine, but 2 × 4 isn't.
Before a big change like a percentage adjustment across a whole table, save a copy of the map. Undoing one bad keystroke is easy. Undoing a big change you don't notice for a week is not.
