    Hi all,

    I've been slowly working on my 328i turbo for some time now.
    Currently the cylinder head is off whilst i wait for a new MLS headgasket to arrive - in the next few weeks it should all be going back together & i'll try and take some pictures of the progress as it goes along.

    Starting from the bottom...

    Standard 328i bottom end - M52 block (was going to swap for M50 but lack of time & money ended that idea)
    Single vanos kept.
    MLS cometic headgasket 0.140"
    ARP head studs.
    Working on modifying a Toyosports e30 turbo exhaust manifold.
    38mm Wastegate.
    A/R .50 turbocharger - was running it at about half a Bar with standard headgasket, hoping for 1 - 1.5 Bar with the new setup.
    All custom downpipe & de-cat exhaust 2.5" straight pipework.
    I've kept the 'front' 2 O2 sensors, but not the 'after cat' 2 sensors - as there is no longer a cat.
    M50 inlet manifold.
    Currently using a moderate size universal intercooler - but looking to upgrade that soon (any suggestions?) maybe an Mitsubishi Evo one?
    MAF sensor before throttle body, after intercooler & dump valve.

    It was running fairly satisfactory on the standard ECU but this is where i need some advice...

    Obviously a stand alone EMS running a few different maps would be nice (in an ideal world with a bottomless pit of cash!)

    Is there anyone out there with experience of re-mapping the existing ECU?
    I'm a bit out of my depth when it comes to the electronic tuning, I'm more of a nuts & bolts guy!

    I really just want to make sure it's running safely, efficiently & maintain some reliability...

    I'm sure i've heard somewhere that the standard MAF sensor is a bit of a restriction up to 350bhp, so is it possible to 'by-pass' this on the standard electronics?

    Thanks in advance

    The only way I can see you doing away with the AFM is to install a piggyback or an emulator.

    Tuning is always going to be expensive. You'll need bigger injectors too.

    One option that has been proven to work many times would be a piggyback SMT6 - it can run secondary injectors for more fueling and also retard your ignition. It comes with tuning software and its pretty easy/ cost effective to set up so saving you time on the dyno.


    I have a set of M3 injectors for you if you want them (PM me your addy and I'll post them out to you).

    Thanks will_uk_74.
    How much do you want for the m3 injectors? Do you know the flow rate?
    I'll probably be looking for 550cc plus for a decent amount of power.
    Gunni (Gstuning) has suggested a vems system that he has experience in tuning, so I'm pretty sure I'll be going down that route as he'll do me a full PnP setup at a pretty good price...

    If your changing to some sort of aftermarket management the afm will go in the bin, simply replace with a map sensor, job jobbed

    Think they're about 330cc so only good if you decide to go piggyback and using them as secondary injectors. Free if you need them...I have many.

    BUT the VEMS is a better solution for sure and Gunni knows this system inside out. The way to go I think...
