The ESP toolbar, left to right
| Button | What it does | When we use it |
|---|---|---|
| Open File | Opens the folder where your maps are saved | Loading a customer's map or a base map |
| Connect / Disconnect | Starts or ends communication with the ECU | Going online, or cleanly dropping off before unplugging USB |
| Save As | Saves the map under a name and location you choose | Before every big change, so there is a version to go back to |
| Copy | Copies selected table data | Moving values between similar tables |
| Paste | Pastes copied data into the highlighted cells | Same |
| Undo | Steps back through your last changes | That edit you regretted |
| Redo | Steps forward again | Undid one step too many |
| Main Setup | Opens the main configuration page | Engine, trigger and fuel system setup |
| Table Axis Setup | Edits the axes of the table you have selected | Adding breakpoints or changing what an axis follows |
| Change Units | Sets the units used for channels | Switching kPa to psi or °C to °F |
Make Save As a habit with a date in the file name. A trail of saved versions makes it easy to compare changes and recover from a bad edit.
