Knowledge Stage1-4 ECU

Stage1 / Stage2 / Stage3 / Stage4 как определить

Stage naming is not enough. WRQ reviews hardware, fuel, logs, temperature and target use before choosing calibration scope.

Stage Planning

Stage labels are useful only when tied to real vehicle data.

Stage1

  • Mostly stock hardware.
  • Fuel, temperature and logs checked.
  • Daily drivability and stability prioritized.

Stage2 / Stage3

  • Intake, exhaust, cooling, turbo and fuel system reviewed.
  • Logs and dyno conditions guide calibration.
  • TCU and CPC limits may matter.

Stage4

  • Large hardware or special-use projects.
  • Needs project management, not one-off file edits.
  • Risk, use case and legal responsibility clarified.
