I was wondering if anyone knows what the units are being measured in evoscan for airflow/rev? Is airflow in lbs/min? I am trying to figure out where I am at on the fuel map (low/med/high) for a 99gst eclipse. Or if anyone knows a way I can figure out my max lbs/min airflow using evoscan, it would be greatly appreciated. Thanks

 

Its in Hz

 

I’m not talking just about airflow. Airflow is measured in Hz. What I am talking about is the display airflow/rev it says its function is 200*x/255. Would like to know what x is and where 255 came from? In the units column it is calling it as load. Thanks

 

The 255 is there because it's an 8-bit value. I never log that value so I'm not sure what it could really be.

If you are looking for an accurate way to measure airflow, try JB's airflow calculations. https://www.evolutionm.net/forums/sh...d.php?t=299660 He gives the formulas for g/rev and lb/min.

 

Thanks man, that helped out a lot!
