    So any properties of the wire (resistance, inductance, capacitance to ground, etc) will influence the amplitude (height) of the sensed voltage, and I can imagine it could influence the arrival time of the signal where it's sensed.
    I'm no EE, but I believe the first half of your statement to be true. I don't think that it affects the arrival *time* of the signal, however. I think it confuses the ICM because the amplitude of the signals is all wrong, and depending on how the circuit was implemented, it could be filtering 'out of bounds' signals to the point that it can't tell which event was 1 vs 4.

    But yes, OEM-ish cables and good, cheap copper plugs (NGK seem to be the favorites) are the way to go.
