Looking at the lambda link in car it flicks between LEDs crisply without flickering. Does it have a low pass filter?

On my car the signal has always been quite dynamic and flickery - DVM never got a steady signal, and my LED gauge works best with fast acting LEDs which flicker. I pick the brightest one.

I am used to reading it and don't think it is a problem, and if the flickering is representing the signal I would rather see it in all its glory and judge for myself, just wondered what others get - does the Dawes one flicker? Do those who built my circuit find it flickers or switches crisply? Certainly with a clean voltage it switches crisply.

I wouldn't like to think it is my dodgy ground from the ECU? ;)

John, no problem with mine, clean transition from LED to LED, no flickering.

Where do you take power and ground?

Are you using the bypass cap on the power that I am?
