    Base Running Airflow

    Hello, I am running a 3-bar speed density tune and I'm in the process of tuning idle after a cam swap. Should the Base Running Airflow table be tuned by logging Dynamic Airflow or Idle Desired Airflow? Once the Base Running Airflow table is dialed in, should Dynamic Airflow match Idle Desired Airflow while idling?

    Thank you in advance for the help

    I used Dynamic air to set up my BRA. That will give you a good place to start. Then tweak it from there to suit you and your setup. Make sure and log the same units in Dynamic as you have in your BRA chart.

    I personally go for short term and long term idle trims. Be aware those values "stick" when not stopped. You have to filter it.
