What's in the Edit menu
ESP's Edit menu is where the table editing tools live. Most of them work on whatever cells you've highlighted in the current table, so it pays to get comfortable with selecting cells first. We've grouped the commands by job rather than listing them in menu order.
History and clipboard
| Command | What it does | Our tip |
|---|---|---|
| Undo | Reverses your most recent table change | Your best friend when a percentage change hits the wrong cells |
| Redo | Puts back the change you just undid | |
| Copy / Paste | Copies the highlighted values and drops them somewhere else | Great for moving a tuned row to a similar area, then refining |
Changing table size
- Insert Row/Column: adds a breakpoint to the selected table.
- Delete Row/Column: removes the selected breakpoint(s).
Adding a breakpoint where the engine changes character, like where boost comes in, gives you finer control there. See modifying tuning tables for more.
Nudging values
There are three step sizes each way: Increase Value and Decrease Value at normal size, plus Small and Large versions. We use the small step for fine fuel trimming on the dyno and the large step for roughing in a new area.
Setting values directly
| Command | What it does | Our tip |
|---|---|---|
| Value Change | Replaces the selected cells with a number you type | Quick way to set a whole region flat |
| Percentage Change | Raises or lowers the selected cells by a percentage | The go-to for fuel, since lambda error is proportional |
| Linearise | Evens out values in a straight line across the selection | Smooths steps between two known-good cells |
| Copy Left / Right / Up / Down | Copies the current cell's value into the neighboring cell in that direction | Good for filling in untouched cells while you work across the map |
Quick Tune
With a wideband O2 sensor enabled, Quick Tune corrects the fuel cell the ECU is using right now, based on measured lambda versus target. Quick Tune - Above does the same and also applies the change to cells at higher RPM and load, which speeds up roughing in a new map. Use it on steady-state cells with a warmed-up engine, and always sanity-check the result. See the ESP Quicktune feature for the full method.
Find
Find opens a search bar, handy when you'd rather type than scroll.
Undo is useful, but it isn't a backup. Save a copy of the map before any big editing session so you can always get back to a known-good file.
