When I converted to CFM, I borrowed the equation as defined in a thread on another forum. Thread is here:
Grams per second-cfm?IAM of 15? - NASIOC
I understand as well that it is apples/oranges, but it's the best I could come up with.
Have you been able to determine if the value being logged for MAF is just one of the MAF's, or some kind of aggregate of the two MAF's?
