WebOpen loop vs Closed loop - Different operations both the stock ECU and the AFR+ can function under independently. Open loop means NO fuel trimming is occurring based on the O2 sensor signal. Closed loop is using the O2 sensor input signal to react rapidly to the changing conditions and make fuel trims to match the desired air/fuel mixture. 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.

WebOPEN-LOOP GAIN . Unlike the ideal op amp, a practical op amp has a finite gain. The open-loop dc gain (usually referred to as AVOL) is the gain of the amplifier without the feedback loop being closed, hence the name “open-loop.” For a precision op amp this gain can be vary high, on the order of 160 dB (100 million) or more. first ssi or medicaidWeb18 de ago. de 2024 · Open-loop operation solely relies upon the calculated value.
