[Diy_efi] How fast is DIY_WB

[Bruce]

You can easily see individual cylinders on a v6 at 3K RPM.
Ya ever hear about all your eggs in one basket?.
Without a true form of redundancy, I wouldn't trust an engine to WOT C/L AFR
control.

I think I remember reading an earlier post that said the DIY_WB was fast
enough to detect a missfire on a 4 cylinder engine up to 3000 RPM.
If my memory is correct this is 12,000 reads a minute = 200 reads a second.
Can anyone confirm how correct this is, I assume that a missfire is a big
lump of unburned fuel and may be a big flag that is relatively easy to spot.
I would if possible like to know how accurate the sensor is likely to be
when the mixture is changing and whether it would be realistic to expect the
DIY_WB to be able to provide closed loop control at higher revs, where the
mixture would be more or less right and the DIY_WB would be massaging the
mixture up and down.
