Scarecrow recommends the cruise-first tuning order. Idle airflow first. VE/fuel tables second. Spark last. Within each, sensors get sanity-checked before you touch fueling tables, and the knock sensor gets calibrated before you walk timing in. The progress box above orders sections that way — start with the lowest order number that's still red.
Each section has its own commit gate: every change-producing subsection has to be Apply or Reject before that section's button turns green. Once a section is fully committed, its progress light goes green here. The dashboard re-reads state from your active session, so refreshing this page reflects whatever you've done in any section tab.
The "Commit ALL" button at the bottom is the future entry point for assembling all section changes into a single .hpt cal file ready to flash. For now it shows a toast describing what would happen.
