Ever since I found out the Adaptronic was capable of this I've wanted to try it - and it works very well
Here's how it works - rather than using a spring loaded valve to bleed of pressure from the wastegate actuator and increase the boost it opens at, a solenoid air valve is put in the actuator pipe. This valve is controlled by the ecu and bleeds off pressure to the actuator till the required boost pressure is reached. |

To set this up you'll need an analogue TPS, and some sort of solenoid air valve - this is the one I used (£18.50 from fleabay).
Conecting it is relatively simple - the valve is connected to a T piece in the wastegate actuator pipe and the valve is wired to a +ve feed and Aux 3 on the ecu (6 pin connector, green wire) |

There's a very good 'How To' on setting it all up here: http://www.adaptronic.com.au/forum/index.php?topic=22.0 though thers a couple of notes I'd like to add:
Step 2) The wastegate output is set on the Aux Out tab in wari - I used aux out 3 which matches the green wire mentioned above. and don't set the frequency to 23Hz, this matches the frequency of the IAC and causes all sorts of slow running and transient throttle problems.
Step 3) I found TPS %55, MAP 120 and duration 1500 worked well.

| Anyway after a lot of fiddling this is what I'm getting now - I still need to tweak the duty cycles a bit, especially in the higher rpm range but it's a reasonable boost curve and certainly feels nice to drive. |

Once I've got it to the target I think I've just about run out of getting more power out of the engine without changing the turbo and injectors. I'm guessing I'm getting somewhere between 80 and 90bhp, I'd like to do a dyno run soon and find out.
But before I do anything more it's got to be time to leave tuning alone and do something about the brakes and tyres! |

Great stuff Fxdlidon ! 
Thanks for the details. How does the car feels now ?
I'm really pleased to see that it doesnt look very hard to do even for a beginner like me... I'd really like to have an Adaptronic with all the mods listed around here on my incoming Cappuccino ! 
Edit: I'm reading the thread you linked. Mmm, forget about what I said. It seems a little complicated to calibrate the bleeding valve  |

Car just feels like a much bigger car - so much so that I keep forgetting how small it is when I pull away and nearly stall it
The setup is nowhere near as complicated as that thread sounds. I was initially put off by it but once you start playing, it's much easier than it sounds, although a bit fiddly - the instructions could do with being translated into real english I think! |

It really is amazing how many extra features are built into this ECU! So you now have a fully controllable electronic boost controller as well as everything else  If only I'd had the money to get one on the group buy  |
Drop me a PM if you would like to be added to the ClubCappo Member Map. More details can be found here.

It's certainly a great bit of kit I think the bonus's you get built in almost outweigh the initial outlay if you had to buy the add-on bits separately.
Only next time I start playing I think I'll go for something in there that's a bit less fiddly to set up like the turbo timer or traction control. |

| I'd say that goes without saying too to be honest. Buying everything that the Adaptronic can do separately would cost a fortune. |

Tottaly agreed a fantastic bit of kit and in the long run cheaper than all the add on bits and pieces. I was going to set up my boost control via the adaptronic but have decided to stay with the Gizmo IBC I have as it has 4 boost and gain settings that can be changed at the touch of a button while driving.
The adaptronic manual is a bit confusing to read but from experience when you are altering settings in real time via a laptop it seams to all come together and is actually quite easy. |

| Sorry about the lack of pics. The battery on the camera was flat while I was setting up the hardware but next time I've got the engine cover off I'll take some, wont be for a few weks though I'm away for the next couple of weekends. |

Kei - The picture Don has drawn above shows how it connects to act as a bleed valve as a lot of people already have (including you?) using a manual spring bleed valve instead of the electrically controlled solenoid valve. The valve will bleed until the boost pressure reaches the setting in the Adaptronic, then energize/de-energize to stop the solenoid venting/bleeding and therefore open the wastegate.
The other way it could be done is with the solenoid valve in series with the boost pressure hose from the turbo to the wastegate actuator, but this time the solenoid valve will be closed until the set boost pressure is reached, then open to pressurize the wastegate allowing the boost pressure to reduce as normal. I'm no good with pictures sorry!
Hope this is what you meant and it doesn't sound patronising!
Nige.
P.S Adaptronic is certainly a great piece of kit!

It would actually be more efficient this way, but if the valve failed, for some reason, there would be no way for the wastegate to open - not good! I think this is why they say to do it this way.

It makes sense now, i scanned the fig a bit quick
By using a tee peice it means the solenoid can always be accessible too and fixed up near the relays (front passenger corner of engine bay).
Great work Don! Looks like this ECU is becoming more popular, James at Capp sport has shown an intrest too, although he recons it needs to be dyno'd proper on my car. Once it's all hooked up again and running it's going back for him to play around with it and see if it's a viable option for the Capp Sport cars.
Next step launch control? |

It'll be interesting to see how well the ecu actually does tune the engine - that'd be a good test. To help it along a bit I've been dropping some big hints about xmas and Wideband o2 sensors - well it might work

The problem with launch/traction control and flat shifting is the need for a 2nd set of speed sensors picking up from the rear wheels or driveshafts - I'm still trying to figure out a neat way of doing this  |

Ouch that's a lot of money! - and no pic to let me nick an idea. I think I'll try and figure out something rather cheaper first.
That's right mvss and svss |

Well I could get a bigger turbo and a set of bigger injectors for that kind of money - there are certain priorities here
(...or even spend it wisely on upgrading the brakes and tyres) |

Which one of these should I get ?
Small one or bigger one ?
If you know of a better valve with shipping to France, please let me know |

| The small one would work fine but it would need to be fitted to a pipe T'd off the wastegate pipe. The idea is to blead pressure away from the wastegate to prevent it opening as soon as normal. Have a look at the diagram at the top of the thread. |

Hi Don,
I'm a bit lost as to what kind and size of connector and / or T piece I need to get it fitted. I haven't yet looked at the cable I need to cut and connect to, so I don't even know what size they are.
Could you enlighten me please ?
If I can't source what I need here, I'd be glad to buy a T piece (or more) from you Don |

| If I remember rightly (someone correct me if I'm wrong) the wastegate pipe is 4mm inside diameter so a 5mm T will do the trick, try and get a metal rather than a plastic one as it could get quite warm. |

Just ordered a 4mm and a 5mm T, both plastic unfortunnatly. I'll hope it's strong enough.
However I couldn't find on internet any 1/4 NPT connector, so I think I'd like to get yours, Don.

Don,
It seems the valve I bought isn't really a good choice for controlling boost. Under 16% duty cycle, it does nothing, at 16% it opens and closes quickly (25Hz I guess) and over 16% it just stays open and even get stuck opened or closed...
What's the behaviour of your valve ? |
