AFR graph Take a look at my AFR graph. I just installed a Maximizer w/FJO WBAFR. The AFR graph is very jagged. I've never seen an AFR graph so I don't know if it's normal. If its not, I'm guessing I have a grounding problem. Before I start pulling stuff apart, I want to make sure the graph is not normal. I'd love some feedback and maybe you could include some of your graphs.

It's normal for closed loop but why do you remain in closed loop
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.
