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?
