Preset calibrations often come with tuning software.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Preset calibrations are built-in starting maps in many tuning software packages. They provide ready-made baseline configurations for a range of engines and setups, so you can begin tuning without starting from scratch. This saves time, helps you observe how changes affect air-fuel, ignition timing, and boost, and gives a safe reference point before you make custom adjustments. While not every scenario will have a perfect preset, the common tuning tools typically include these presets to speed up learning and testing. That’s why true is the best answer here.
