    Accelerator sensitivity

    I have a 2003 model TD6 and the accelerator pedal is very sensitive. I rarely have to push it more than a quarter of the way down, which makes it very twitchy. Can the sensitivity be adjusted or do I have to continue with a sore foot from trying to hold it up? Jim

    Its a drive by wire throttle and it sounds like your car has had a remap because the normal setting is a bit lethargic on the take off . so you can have the throttle response re-written I just have no idea where you can get it done

    G'day Jim,

    As Axle said, it's a drive by wire system. It has two "normal" maps that work differently between high range and low range.

    In high range you only need about 1/3 (I think) of the throttle travel to get full throttle happening. Not entirely sure of the reasoning for this but I guess it helps get you to whatever speed required efficiently and then you can put the cruise control on. It also leaves a bit of throttle travel left for things like kick down response for overtaking, steep hills and so on.

    When in low range the throttle remaps over the whole travel so that you get much finer response for negotiating obstacles slowly and with much better control. No jerky throttle when rock hopping.

    If you've got a copy of RAVE, I vaguely recall that there's a good description of the way it's set up in the service manual system descriptions.
    Sorry this isn't my most eloquent response. The short answer is, that part throttle travel is "normal".

    Cheers,
    Iain

    Thanks. It is just sensitive and kicks back easily. I should be used to it after four years but I thought I would ask. Jim
