  🔵 Fuel System Control

  • Injector opening time

  • Injector scaling

  • Target lambda (closed loop & full load)

  • Lean best torque maps

  ---

  🔵 Ignition (Spark) Control

  • Spark advance maps

  • Knock retardation

  • ECT/IAT-based corrections

    • Difference between Keihin 1.5 Turbo vs 1.5 NA

    • 🔹 Whether it works on your specific ECU number
