Bandwidth = GBW/Noise Gain. Where Noise Gain is defined as 1/Beta Beta being the feedback fraction which is equal to R1/(R1 + R2) for both the inverting and non-inverting amplifier configurations.

"Web15 de mai. de 2009 · Closed loop is basically a condition where the throttle position is very constant (i.e idle and cruise). So all the PCM needs to do is make sure the a/f stays about the same, and all is good. As soon as you open the throttle some, it has to go get IAT and MAP values to determine what to do based on its programming. " - Open loop vs closed loop efi
