    God knows what that is doing to the turbo and can the engine cope with so much more pressure without bending the rods etc?

    Surely there must be a reason why BMW didn't do this in the first place?
    Thats a good question why didn't BMW do it, could it have been because of EU regulations or taxation reasons, just ideas, i guess i am just trying to convince myself it's ok to leave it on.

    can you say why you went for the box in the first place? - did you want more power or mpg or perhaps both

    i've been running an E60 touring m sport 525d for about 8mths and am considering a remap for 2 main reasons

    i'm finding the mpg pretty poor around town eg 22-26 mpg (40 on a run though)

    also the engine is a bit 'noisy' - I'd thought being a larger BMW engine it would be quieter (some have said it's because it's a 5 cylinder engine - others have said it's 6 - leaving me somewhat confused)

    considering an 'eco' tune

    any thoughts?

    I too have just purchased a Drake box 2, basically to see what the crack is as i am new to Beemers and want that wee bit more out of the engine until i upgrade to a 330d next year, been looking at various threads regarding mapping boxes etc and unsure as whether the responses from tuning Co's towards in line boxes are totally genuine or they see it as competition.

    Going by the response on the feedback on the Drake 2 ebay site by all accounts its okay for what it is, any user feedback would be welcome though!


    All the best Drooski

    I fitted an in-line tuning box to my 2005 320d. It definitely feels a little quicker. But the main gain is on fuel consumption. I regularly do motorway journeys, and whereas I was consistently getting about 50 mpg, this increased to just over 60 mpg with the box. I tested this about a dozen times and I always get about 60 mpg. Addmittedly this is on the computer so it could be a bit out. But I too have concerns about any nasty side effects. Everyone seems to "talk" about these boxes being risky, but is there any evidence?? Or is it just the remap boys scaremongering (no offence!).

    Tuning box's are ok but they work on a % increase all the time.
    Were a re-map can have the same increase as the tuning box but when its needed..
    So when your sitting at the lights a tuning box will still be asking for 7% more fuel etc.. Thats way some newer car's after time will bring up errors.(not good when its not needed)

    As with Motech remap (cant speak for others) Our tuning kick’s in over 50% loud the throttle making a much nicer drive with no smoke etc etc..

    Just think about how much throttle you use when sitting at 70mph. Our mapping at 70mph would read from the stock file if you like. When put your foot down then it reads from a different set of load maps giving you the power on request. A tuning box will give a % all the time..

    So there fine as long as your happy on how they work and why a re-map is better .

    Does anyone know how the fuel consumption is measured in a BMW. The reason is if you fit a chip box and the fuel pressure is increased, is the mpg based on some form of calculated mapping and could give a false reading or is it the real fuel volume that is being measured? This is a similar premise to the fact that speed/distance is measured by counting wheel rotations, so if you fit bigger wheel your fuel consumption will go up, because you are not getting less wheel revolutions per gallon! Anyone following this thought, well back to the question - how is fuel consumption measured?

    yep, it's telling you the fuel consumption if the fuel pressure was normal.
    The ecu/combi etc has no idea of the extra fuel going in.

    Do a brim to brim test. What I found when doing tests is this. If the mpg goes up by 10mpg, say from 50mpg to 60mpg the real mpg has dropped by 10mpg from, 50mpg to 40mpg !!
