Home Page

Your configurable dashboard — a 2×2 grid of live tuning previews

The Home page is the first screen you see when DigiTune GTS opens, and you can return to it any time with the Home button at the top of the sidebar. It shows a 2×2 grid of preview tiles, each giving an at-a-glance, read-only snapshot of one tuning view. Once you've loaded a map and one or more logs, the dashboard lets you spot the overall state of your tune — fuel error, boost, knock — without clicking through every page.

The four tiles

Out of the box the quadrants are arranged like this. You can change any tile to a different view (see Customising the layout below).

Position	Default view	What it shows
Top-left	VE Table	The current fuel/VE table as a heat-map-coloured grid.
Top-right	Fuel Error vs Load	Measured fuel error (%) plotted against engine load.
Bottom-left	Boost Profile (MAP vs RPM)	Logged manifold pressure against RPM, with the closed-loop boost target line.
Bottom-right	Fuel Error vs RPM	Measured fuel error (%) plotted against RPM.

Before you load data Until a map and log are loaded, each tile shows a "Load a map / log to populate" message. Tiles that need data the current files don't contain (for example a Knock preview when the log has no knock channel) also stay as a placeholder.

Opening the full page

Every tile is a shortcut to the page it previews. To jump straight to the full, editable version:

Left-click anywhere on the tile, or
click the ↗ (open) button in the tile's top-right corner.

The click target is fixed per view, so the destination always matches what you're looking at:

View	Opens
VE Table	VE Table page
Fuel Error vs Load	Global Row Trims (Utilities tab)
Fuel Error vs RPM	Global Column Trims (Utilities tab)
Boost Profile / Boost Open-Loop Table	Boost page
Ignition Timing	Ignition Timing page
Knock vs RPM	Knock Threshold page

Customising the layout

Right-click any tile to choose which view fills that quadrant. The menu groups the available views under Tables and Plots:

Tables: VE Table, Boost Open-Loop Table, Ignition Timing
Plots: Boost Profile (MAP vs RPM), Fuel Error vs Load, Fuel Error vs RPM, Knock vs RPM

A tick marks the view currently shown in that quadrant, and the factory default for the quadrant is labelled (default). Choose Reset to default at the bottom of the menu to put the quadrant back to its original view.

Your choices are saved automatically and restored the next time you launch the application — each of the four quadrants is remembered independently.

Previews are read-only Tiles are snapshots for monitoring, not for editing — you can't change values directly on the Home page. They refresh automatically whenever the underlying data changes (after a reload, or after you edit a table on its own page), so the dashboard always reflects your latest tune. To make changes, open the full page from the tile.

Typical workflow

Load your map file and logs (see Loading Files).
Open the Home page to review fuel error, boost and knock at a glance.
Spot an area that needs attention — for example a band of large fuel error.
Click that tile to jump straight to the page where you can adjust it.
Return to the Home page; the previews update to show the effect of your change.
