https://docs.emtronaustralia.com.au/engine-management/tuning/torque-management/pedal-demand-filter/index.htmlIntroduction The ECU takes the raw Pedal Position Sensor 1 input, passes it through exponential filter to help smooth out signal fluctuations, then generates a new runtime Pedal Position Demand. Pedal Position Sensor -> EXPONTENTIAL FILTER -> Pedal Position Demand The filter coefficients for the exponential filter are adjustable using a table. These filter coefficients can be used to heavily filter small throttle corrections, while allowing large throttle changes to have little or no filtering. By heavily filtering small throttle corrections, throttle sensitivity can be reduced, helping the throttle “feel” when driving over bumpy roads or when making small throttle changes. Little filtering when making large throttle changes helps to give a fast throttle response when a large acceleration or deceleration is requested.Hugoen-us
