1. A system comprising:
a control circuit configured to receive an input signal and to control at least one engine output based on the input signal; and
an adjustable low-pass filter configured to:
receive the input signal; and
filter the input signal prior to forwarding the input signal to the control circuit, the adjustable low-pass filter having a first setting in which the adjustable low-pass filter has a first cut-off frequency and a second setting in which the adjustable low-pass filter has a second cut-off frequency, wherein the first setting configures the control circuit to be used with a first sensor having a first dynamic range and the second setting configures the control circuit to be used with a second sensor having a second dynamic range.
