    What is impendence? I here it refered to when we talk about fuel injectors. I know what an oxygen sensor is, but what is a wideband? And when we talk about turbos what is a T2, T3, T66?

    a wideband o2 sensor reads more accurately than a stock one. the stock ones are only accurate at 14.7:1 a:f where a wideband will read anything.

    impedence is synonymous with resistance.
    a fuel injector is opened and closed with an elctromagnetic coil.
    This coil if measured has a reistance when out of circuit.
    When in circuit and has a waveform with a duty cycle (almost like an alternating current) the coil is now said to have impedence

    calculation for impeadence is Xsubl = 2Pi(f)(l)
    where f = frequency
    and l= Henry's (measurement of a coil)

    the short answer.
    T3 ,T4 or T66 has to do with the sizing of the turbo.
