Hmmm, looks like you've made your own boost controller and interfaced it with the original ECU...
Your as mad as a pink cat.

No mate, I am even madder than you think. The boost controller is going to be inside the ECU, that is, not extra hardware, it turns out it is already there. And there is a free timer interrupt in the program and that's all I need to have full electronic boost control. The open-loop mode is already implemented and working. The closed-loop is still a todo, but it will happen soon.
So you made that the original ECU understand boost, that thing that was impossible...
Awesome, hats off chap, and there was you claiming you were rubbish at electronics.
Nice work.
By the way, make that 3 pink cats...

Boost it knew about already before, but it could not control it. Now it can.
I really needed professional help with this in terms of electronics, I can steer the output, but it is too weak for the 5.4 Watt valve, a mate of mine drew me a quick one-mosfet-two-resitor diagram to fix this, something I was just not able figure out myself, even though I have found an almost required schematics on google.
Anyhow, I will keep you posted. The car needs some maintanance first, in particular sorting out a problem with the sticky waste gate (this actually gave me the clue to think about EBC). I also need better wheather like you, it is so unpleasantly cold outside right now

does that mean i can turbo mine soon?
If you ask for my permission, then yes, go ahead
Integrated ebc.. mad man! Cant wait to see the results!
Nice work.
So how long before we see Woj edition IAW flooding the market place?

You see, this is really not economical. Would you pay ca. 200 Euro for a premapped ECU, and another 150 for the EPROM emulator to be able to map it yourself (which is a must if it is supposed to be of any practical use)? For this kind of money you can almost get the EMU that does so much more, including coffee brewing
. The only win with this technology is that the loom stays (almost) untouched. Besides, for me this is more of a science than business k:Regardless of that, I still do have a couple of more ideas along the direction of still extending the ECU capabilities
Make that £140 because the Det 3 has all these features.
However modifying on this level is the very foundations of coolness. Lifting a bonnet and having the full manufacturer appearance yet being able to toast most things in your class is the epitome of a well tuned road car. Not to mention rather useful in stop checks... :devil:
So what new features do you have in mind, perhaps you can squeeze in some lauch control.

Launch control is a piece of cake. But I do not race the car, so lower priority. Two other things that are on my mind: wide band lambda fuel correction and vehicle speed. The latter for additional boost control, the former, well, for obvious reasons. Both are doable, but would require soldering inside the ECU and hence would not be "hardware independent".
Wide band control would be pretty awesome but as far as increasing performance I think your closed loop boost control is pretty much the best upgrade you could have made (for a turbo of course).
Surely you must be thinking about a bigger turbo round about now.

No, no bigger turbo, I think with EBC I can get out of this engine what it can safely produce without touching the engine internals, that is 140 hp or so. The car is slowly dying anyhow, no point making heavy machanical investments.
Anyhow, have been busy last two days, sorted out problems with a sticking WG (again), and prepped the car for the EBC: MBC dismounted, engine loom modified, cables to a dash switch for changing boost maps sorted out, and a mounting bracket for the valve "fabricated". Nothing left to do now really but to tune the thing. This though has to wait probably for after Easter, as there are prohibiting factors coming up. But we'll see

Well mates, it works and it works good. Though I have to fine tune it still. Today I made several full throttle runs to roughly figure out the duty cycles, and then made a preliminary setup for closed loop mode. Attached is the log from the first attempt in closed loop mode. There is a spike that I now need to tune down. After the spike the boost holds at a solid 180 kPa MAP (the figure on the plot is slightly decalibrated, has to do with certain electronic contraptions I made to convice the Zeitronix logging module to interpret my MAP sensor correctly).

well done!
