Modifying Tuning Tables

Elite Software Programmer › ESP - Navigation › Tuning TablesUpdated Sep 2026

Every table in the ESP navigator can be edited, and most tuning comes down to changing cells quickly and accurately. Here's an overview of the editing tools in ESP and where to learn each one.

Editing tables in ESP

In Elite Software Programmer, every tuning table in the ECU navigator can be changed. The workflow is the same everywhere: open a table from the navigator, select the cells you want to work on, then change their values. Once you know the editing tools, fuel, ignition, boost and every other table all work the same way.

The tools, and when we use them

ToolUse it for
Selecting cells and deselecting cellsChoosing exactly which part of the table to change
Increasing and decreasing valuesNudging cells up or down in steps
Currently used cellSeeing where the engine is operating right now
All Ranges and All Ranges above modesApplying one change across a wider range of the table at once
Inserting and deleting axis pointsAdding resolution where the engine needs it
Copy throughCarrying values across a range of cells
Watch your air-fuel ratio

Never change fuel or timing under load without a fast, accurate air-fuel reading. A wideband oxygen sensor responds quickly enough to catch a lean spot before it becomes a problem. A narrowband sensor won't.
