  1. Another way other than the iPhone  generic tray is to mod the Nokia tray.

    I modded my Nokia one to fit a iPhone 5 but didn't include a passive aerial. No issues with reception I noticed at the time. 

    End up getting an iPhone stand and used the iPhone mount from it.

    used ULF  for Bluetooth.

  2. Interesting position if true.  

    Consumer protection website says to call BMW. Guessing this could get quite political for BMW NZ and damage the brand as a result.

    Where do BMW stand legally if a large group of jap origin owners grouped together and legally went after BMW on the grounds of a world wide recall. Would the group go after BMW NZ or BMW Ag ?

    Thoughts anyone ?

     

     


  3. Watching with interest.  

    My car seems to be going down in power.

    first hub dyno at 48,000 km saw 230kw at hubs. Car was one of the quicker M3s I'd tried going by butt dyno at time of purchase .

    Second Hub dyno at 90,000km saw 210kw at hubs

    Third roller dyno engine run at 122,000 saw 183kw at tyres   (Running Mobil blended 98 which causes pinking on the M3)

    Running SMG so thinking about csl  software for subframe longevity and restoring power.

    Think I use to hang out a bit with the son of said surgeon. Lived in Karori, city end ....

    Surname starting with K.

    same Wellington car ? Orginal owner had passed away and the car had 97,000 kms in 2014. Was immaculate then and still looks as good.

    Isn't 210 kw enough ?


  5. So been running the media player and working through having the USB hub power up and down when the raspberry Pi wakes up and sleeps. A start up script triggers one of the pi's gpio pins high which triggers a audrino relay, this turns in the 12 volt to 5 volt power supply . This powers the hub and give the blueray player enough power to operate.

    the audio quality achieved by the Pi and optical dac straight into the dsp as worked out very well. With the system at full volume there is no background noise .

    Have given the system a bit more time alignment so from the drivers seat the left and right speakers have enough delay and offset for the stereo image to appear dash hieght and centred . I've also moved the midbass roll off up to 75 Hz without effecting midbass impact too much.

    Also added an M3 theme to the media centre menus.

    In the disassembly of MDS50 and MSS54/52 ECU code.

    The MSS50/52/54 ECUs all have a very advanced knock control system. It has a per cylinder hi and low flag system which allows the ECU to determine the onset of knock and prepare for it. The other variables in the ignition retard equation are IAT and Coolant temps.

    There is quite a bit of logic that goes into it which I'm not going to stick on a public forum but it is the reason a lot of you will see wild differences in power.

    The S5X engines run quite high compression ratios for a road engine on pump gas and with that comes a close to the edge ignition control system. 

     

    Here is some dyno software I developed for it ... top right is the knock control system read out.

    Quite interesting . I notice the car knocks quite a bit of late ( fourth gear up inclines) Doesn't like the blended Mobil 98 for some reason where it seems to knock even more. I'd largely run it out of the tank on the way to Auckland.

    Last dyno day (hub) about 30,000 kms ago saw a result quite a bit higher. That time they where saying the car was on the lean side.

    Anyway , enjoyable day and quite a fun 1300km road trip.


  7. I brought a freeview terrestrial tuner kit for the BMW TV module www.pibus.info . I hate having a module that didn't work. Use to watch TV in the car whilst parked up when waiting for the wife to finish work. Not into driving and TV , but its handy to have the audio only sometimes.

    I decided not to go with the USB input for playing media or the ir input. The TV module is still controlled from board monitor.
