From the
DIY Wideband AFR Gauge on YouYube
Adrian Adrian from YouTube wrote:What is the value of the resistance in the capacitor? THANKS
The RC-filter in the video uses a 220 µF capacitor. I believe the resistor was around 1.5 kΩ. I am sure you can tune it for faster response, I used parts available to me. Not sure if you are looking for the ESR?
Adrian Adrian from YouTube wrote:A question The resistor is located on the green wire or the black wire?
The green wire in the video is connected to the resistor in series as can be seen in this schematic. Red is 12V (VIN) to power the gauge. Black is ground.
