So I am Currently trying to tune my 2001 Buick Regal Gs with the l67 3.8 sc on the old scanner or older version of HPT It allowed me to log maf hz vs ltft to dial them in together. My problem is on the new style scanner when I go to make a graph and go to the parameter selector and I click the gear icon with the check mark to show only parameters backed by channels it does not show Maf Frequency or Maf hz it only shows mass airflow. So is this no longer supported or am I doing something wrong?
