    Absolutely fanastic write-up that was of great value to me. I just (last week) completed a very similar install in my 1998 1.8 Z3 (M43) - I had to take a little detour around an M42 head in order to fit the DASC kit, but everything has worked out pretty well.

    I am curious as to which AFR readings you get - It seems like my ECU is doing everything it can to pin it down at 14,7 and it doesn't really seem to go out of closed loop operation with higher rev's ...

    When you cranked up the fuel pressure regulator (clockwise i guess) - how mich did you have to turn it and could you put a few words to what effect it had ?

    Best regards

    Nice, its a lot of work to perfect, but worth it, sort of !!

    as for AFR's, i had a re-map and rolling road session(s) , 3 in all. they remapped the fuel delivery at the top end as it does run a little lean at full load and WOT. that eleiminated most of the 'lean' running at the top.

    subsequent rr sessions with the new filter and exhaust and smaller pulley was approx 2-3 full turns on the rrfpr.

    i am now at 10.5psi of boost running around 11.8 - 12 afr at WOT, this levels out to around 14.5 at level running.

    I have installed a wideband lambda (Innovate) gauge with data logging, very useful and essential in my opinion to prevent any 'bang bang' issues

    the car runs hot as well on a high boost for prolonged periods, i have removed underbonnet insulation , removed the thermostat, new waterpump and electric fan.

    i am now going to sell this set-up and fit a V8

    Hi Mark,

    I just love the look of the (hartge?) V8 crammed into the engine bay - all you need is a large shoehorn ;-)

    So, you had an actual remap done ? That's my problem - there seem to be a lot of people capable of remapping M42's and M44, but the M43 seem to be a somewhat rarer breed (and less potential, i guess) and I can't even find an off the shelf chip for it.

    Do you have an idea about when (at which revs) the ECU goes out of closed loop ?

    I got the innovate LM-2 and consider it an insurance policy - As i said, my DASC has just been installed and for now the stock 0,5 bar is more than enough for me at the moment. I like the DASC, but it's potential is really limited because of the lacking possibility to add an intercooler...

    I would love to read about the V8 transplant - keep up the good work !

    how about going to a dedicated engine management system like the Omex ? it would sort out all your problems rather than using the limited ecu on the m43.

    not sure about what revs/closed loop scenario. i dont think i had that problem with mine and the remap

    with the pulleyboys smaller pulley and 10psi of boost it really moves and makes a loud howl at anything over 3500rpm

    I would love to take on such a project, however since the car is my daily driver i do not think it is realistic. The reason why i did not use the M42 ECU is most notable that I fear that switching the ECU will mess up all the other systems that is has to work with. Perhaps it would work out, but I worry about the DSC, EWS, BC and so on.

    hello mate just read this thread from start to finish and am very impressed
    as that is my next plan to use the dasc to supercharge my 318is but as this car is my daily i just thought i'd ask if what you have done is doable on a daily driver?
    i've already sorted suspension etc so this is my next mod
    another question is i was just about to buy some power pulleys but dont wanna waste my time if they are not compatible with th dasc and relavant pulleys/belts?
    and lastly would having a bbtb be beneficial or not?

    and have you already sold your kit?

    Just read this from start to finish and hopefully you'll still be around (after the V8) to answer a few questions.

    I'm planning on using the DASC on my M42. I would like to know whether the clutch/flywheel (single mass) will cope or not?

    Were any other intakes tried before the ITG?

    Same question as above, but would a BBTB make any difference?

    What radiator did you use?

    Thanks!

    Used a simota carbon airbox before the ITG, the ITG gave more horsepower, i seem to recall around 12hp. the original clutch gives up with the boost in torque. BBTB makes a small difference.
