  1. Looks like a good buy... well optioned!

    Dynamic Drive is quite different to DSC (which BMW added as an option in the '90s), though it compliments it - dynamic drive is a hydraulically actuated sway bar. It allows one wheel to go over bumps without transferring them to the opposite wheel via a solid sway bar. http://www.bmw.com/com/en/insights/technology/technology_guide/articles/dynamic_drive.html

    Yup your right i should check my links before i post them :)

    It works really well and surprising how nimble it makes the car despite its size and weight.


  2. Thought i would give a plug for this 550i for sale on trademe.

    For $19k this is a steal and is fully optioned m-sport including comfort access, comfort seats, logic 7 sound system, dynamic drive*, active steering, 19" rims, remus exhaust and a 2 year autosure extreme cover warranty to go with it. I have seen this car myself and it is absolutely mint.

    *dynamic drive prevents body roll see here

    and here https://www.youtube.com/watch?v=LUsokHgmyio. I think its a rare option on E60s.

  3. A better intercooler and exhaust would probably be ok. Anything else, within road car reason, would be snatching at small power in contrast to what the n54 is already capable of.

    It will all boil down to who your repairer is and how they handle the claim. In saying that if you have Autosure Extreme for the most part you should have no worries.

    "Yes that is correct sir. I put an aftermarket IC, charge pipe and exhaust on the car but didnt touch the ECU its stock and I have no idea why the turbos are blown"

  4. I suppose it all depends on how you define "maniac". I'd love you to elaborate. In public if you wish.

    Edit: please tell me you're not the one with that 'X' on the side of your car... ??? The one sitting in the right hand lane?

    I was kidding dude. I guess i should have used sarcasm tags.

  5. Getting a CEL after a tune is the norm rather than the exception.

    Swap the #5 coil with another and see if the code follows the coil. Same thing happened to me and just bought a new coil off ebay. You might not need to change plugs of there are no more codes or timing corrections.

    -8 psi is normal just the way it reads boost pressure. Mine is the same.

    2FA3 code i don't know what it is think it's nothing. I have this and lots of others but doesn't seem to do anything. Looked it up in the Bentley manual also told me nothing. Wouldn't worry about it. From memory it might have something to do with the ecu being updated and triggering the code when you get CEL.


  6. Ive been getting a lot of PMs asking about the MHD app so best if i update this thread with my comments.

    With the app you can flash OTS maps which are by all accounts very safe and conservative. You can also flash a custom map or backend map to use in conjunction with JB 4.

    If you are just starting out its better to get MHD as its cheaper than all the other options, easier to use and is constantly being updated. Cobb has ceased new development of their maps. And arguably its better than JB4 as its not a piggyback but a ecu flash.

    MHD is tied to your phone, google account and vehicle. So if you ever sell your car the app becomes useless to you. But, if you purchase on a standalone device and google account you can onsell it with your car. Cheap android devices are easily available.

    I bought cheap ebay cables which worked for me. No guarantee they will for you too but these are the cables I got:

    http://www.ebay.com/itm/Micro-USB-Male-To-USB-2-0-Female-OTG-Adapter-Cable-For-Samsung-Galaxy-S3-S4-Mini-/151532877345?hash=item2348103621:g:sCUAAOSwGzlTxcKg

    I recommend you get a 3-way OTG cable not the single. That way you can charge your phone through the USB port at the same time you are logging.

    When first flashing I had a charger hooked up but its not necessary if you have a good battery.
    Before you flash backup the ECU as you cant do this later. Or you can just flash to map 0 if you want to go to stock if you dont have the ECU backup to flash back.
    Once the car is flashed then its time to start logging. Go WOT from 2500RPM in 3rd gear then shift to 4th at 6000RPM and keep going for a bit (do this discretely as you will be going well over 100kms at 6000RPM in 3rd - i think 160 or so). Upload results to datazap and post on E90forum for feedback. Using a higher boost map will show up all the weak points in your car and you are very likely to get limp mode / check engine light. MHD can read codes too which will help.
    In my case I had vacuum leaks and boost leaks. Replaced all the vacuum lines and cleaned out the diverter valves and disconnected to get a bov sound.
    Im running the Stage 1 FMIC map although I dont have a FMIC. In summer will either get FMIC or use a less aggresive map. This map targets 15psi (stock is 8 psi) and totally transforms the car.
    Heres some old logs I took using the St 1 FMIC map - im comfortable using this with no aftermarket FMIC as the IATs are nice and low and not getting any timing corrections.
    Any questions id be happy to try and answer them. Enjoy!
