AFR graph
for so long? That's the question. There will always be "noise"
and most widebands have a filtering function you can use to
get a quieter waveform that still tracks reasonably tight in
time to the gas chemistry. Picking that filter-value is a
judgement call. I'd base it on the high end of WOT, try and
get open loop "barely clean" and it's probably about the best
compromise between hiding information and suppressing crap.

I never got up to WOT at least not for more than a seconed. I'll have to take my car out to the sticks and run a real 1/4 to see that the real graph will look like.
