Mass Airflow Filter Coefficient

This table specifies the mass airflow filter coefficient as a function of engine speed. When in MAF mode, a filter can be applied to the mass airflow signal. This is useful for smoothing a noisy signal and reducing the intensity (or amplitude) of sudden spikes and dips in the signal.

The number is a decimal between 0 and 1, which specifies the strength of the filter. Values near 1 would not filter out much (weak filtering). Values near 0 would filter out the whole signal (very strong filtering).

0 and 1 themselves have special meanings:

• 1 - do not filter the output signal (the output signal is equal to input signal).
• 0 - output null signal (not recommended).
