    Hi Bruce, in my stuff, LV8 = MAF/RPM * scaling factor.
     
    I think the Max Air Flow is the maximum allowed at a certain RPM before the ECM considers the MAF to be defective and uses TPS and RPM for fuel..

        I looked through the archives and found lots of discussion on the LV8 variable. However, I did not find an equation that defines how to calculate this parameter from the sensor data and lookup tables.
         
        Since LV8 is the engine load variable, I would think that this parameter is related to the engine VE at a given RPM. One possible way to calculate LV8 is listed below.
         
        LV8 ( @ given RPM) = ( MAF (g/s) @ test RPM ) / (Maximum Airflow (g/s) @ test RPM ) X 255
         
        For the 87 vintage 1227165 F-Body cars, there is a "Maximum Air Flow vs. RPM" table. I wonder if this table is used to calculate the LV8 parameter????
         
        If the actual equation is documented, where can I find it???
         
        Thanks,
