    Hello all, been thinking for a while now about a remap, seen a place near me that does evolution chips, they are £250 and achieve +£13bhp and +10nm of torque. Do you guys think it's worth it in terms of value for the gains?

    Thanks James

    I would have a word with TheEnd, he is one of our forum vendors and will know the score....

    From my experience it is worth getting a car mappedas the throttle responce is very much improved and any flat spots also disappeared too.We have many forum vendors in the vendors section that do mapping have you asked any of them for a quote?TheEnd did the chip on my car

    Thanks, that was a quick reply from you both, do they all seem to achieve the same power gains? I'm after a place in the Manchester area, where are they based?

    I would have expected more torque, they might have misquoted their figure, but the power figure is about correct.
    It's not going to turn it into a rocket ship, but it gives the greatest change in performance this side of cams and engine swaps etc.
    You don't get the same noise from an exhaust or air intake, but you'd get maybe 4x the benefit.
    The main thing is the feel, sharpness and response that will make the car feel more alive. For value, that's more of a personal choice, so hopefully we'll get a few first hand experiences from various customers / tuners.

    Where are you based 'theend' and how much could you do the remap for? I would prefere to give the business to somebody off here? I am very interested now.

    That's good, I did think the figure was a little low, but typos can creep into big lists of numbers!
    I'm based in Birmingham but I do travel, the total cost would be £220 (£245 - forum discount) plus travelling which would push it up to £270.

    Don't feel duty bound to use someone from here, choose whoever you are happy with first though.

    Not really, the dealer may suspect the ECU, but they can't read a file off, all they can do is update the ECU or force an update if there is no other updates available.
    ie. they can plug in, it will tell the dealer the hardware type, original software, what the current software type is (unaltered by a remap) and if any subsequent updates are available.
    If they do suspect something, the best they could do is reprogram it again so they know what they have.

    For the rest of it, trying to measure the effects of the remap will be close to impossible, they can see fueling and advance at idle for example (which would be unchanged - you don't need to get more power when parked!).
    Taking it for a drive and logging the details, then comparing them with what they would expect would be tricky and time consuming too.
    A diesel would give the game away with the obvious increase in power, and boost levels can be monitored if they feel like it, but generally, the most they will do is run an update to the latest BMW sw version.
    At the age of your vehicle, BMW won't be doing updates during servicing unless there is a specific problem, and you would most likely know beforehand as they would be charging you for it.
