    it's already done to some extent - angular velocity for each power
    stroke is measured, so any cylinder not producing the same "oomph" as
    the others gets individually tuned.

    How does the ECU measure angular velocity? Crank sensor?
    That would really complicate the ECU's program and require a much faster
    processor.

    yes - that sawtooth thing.
    check - and that's what we have! there's a lot of computing power out
    there. this stuff is small beer compared to what's in the average pc.

    The sensor reaction time is nowhere nearly fast enough to do what you
    suggest.

    Tegger commented not long ago on certain Fords having one
    oxygen sensor per cylinder. I googled and found support for
    this.

    Seems perfectly reasonable to me, timing-wise that the ECU
    and O2 sensor could calibrate fuel going to each cylinder.
