    Hi All,

    This my first post so please be patient with me :-)

    I recently had my 325d M Sport (2011) sport Auto remapped by evolution chips (fantastic by the way) pulls extremely hard and the traction control light flashes light Christmas lights on acceleration! Any way enough about that, the reason I'm posting is On 2 accounts and would love any feedback from you knowledgable guys.

    Firstly I took my 325d to my main dealer due to poor fuel consumption. 30.9 driving like miss daisy on various runs etc.

    They had a quick look (30 mins) and said they had reset the auto box which would help! Can someone please explain why this would help MPG.

    Secondly the car seems to be less ferocious in terms of performance. Do you think reseting the auto box has effected my remap?

    Would really appreciate some advice from everyone.

    Thanks
    Breno

    resetting the auto box ECU just means it will now learn how you like to drive
    will not affect your remap

    What MPG was you getting before the map ??

    Also if honest sounds like it could be a bit to aggressive to out the TC light on us less its damp etc.. 325d's need the fuel pressure upping to make good power.. Might be a bit on the High side that would course poor mpg too..
    Thanks Mike
