Mass Airflow (MAF) Smoothing Factor

This value is used to smooth out the raw signal from the MAF sensor. This value affects the output as follows:

• A value of 1 means no smoothing is applied. The output value will be exactly the same as the raw value from the sensor.
• For decimal values between 0.001 and 1, the smaller the smoothing factor, the more dampened the mass airflow signal will become.

More specifically, the current raw value is multiplied by the smoothing factor. The result is then added to the last calculated value multiplied by (1 - smoothing factor). So, if the smoothing factor equals 0.3, the output value will be:

(0.3 x raw value) + (0.7 x last calculated output)
