    Keeping on the power

    When climbing hills, like the Toowoomba Range, the Defender used to die and stagger on the gear change.
    I did a bit of research and discovered the clutch switch basically kills the revs.
    From the book:
    SWITCH - CLUTCH PEDAL
    The clutch pedal switch is located on the clutch master cylinder and is activated when the clutch pedal is operated.
    The ECM uses the signal from the clutch pedal switch to provide surge damping during gear change. Surge damping stops engine speed rising dramatically (engine flaring) during gear change.
    Surge damping assists driveability as follows:
    • Smoother gear change.
    • Greater exhaust gas emission control.
    • Improved fuel consumption.


    I disconnected this a long time ago and noticed I can hold some revs and no stagger occurs and the gear change is better! Has anyone else suffered this problem or tried disconnecting the clutch switch.
    Mines been off for around 25,000 klms and no ill effects.
    Cheers.

    thanks Trev,
    will pass that one on to the Step Father. He's been complaining about that little bugger.

    Just curious to see if anyone else has actually tried this since the original post.
    Cheers.
