    Learn to use the scanner first. Then read the tune off and look thru it and figure out what the scanner is telling you... It takes time to get it figured out if this is your first rodeo..
    But first and foremost, learn to use the scanner.
    If you want to know what data your looking for, open the tune and say if you want to know how the spark tables work. Look at each Axis and it will tell you what it needs. RPM vs Airflow
