Basically airflow / rpm, right?

Ok, so RPM is easy enough. How is airflow calculated?

 

Yes to LV8 calc.

Airflow is derived from the MAF. The MAF scalar tables convert MAF output to airflow.

RBob.

 

So with a scalar of 1.00 in table 6, the max airflow available to me is 255 - 255 g/s. Ahh... now I'm starting to see how this comes about...

Now, say I'm given a MAF flow rate of 84 g/s @ 3400 rpm. Airflow / RPM is going to give me a number between 0 and 1. How does that equal the LV8 value?

Or even the value that it's supposed to be in my calcs, of 163 g/s, over 3400 rpm (hey wait - is this supposed to all be in minutes?)

Say - 3400rpm / 60 = 56.6

Now, 163/56.6 still comes out to approx 2.88. Ok, yeah, can someone expound here?

 

This is the calculation used in the $32 & $6E MAF code:

LV8 = (((DRP * gms/sec) / 256) * Scalar) / 64

RBob.

 

DRP = Distributor reference pulse, yes? How is that figured? (say, rpm/cylinders?)

Is the $32b and $6e calculated the same as the $3a?
