Boost contoller

When you say its dropping mad how do you mean...

The k03 doesnt hold boost well higher up the rev range anyway...

Bill, this is what i actually posted in jamiebennetts topic a while back.



Change the units to psi for a start, so you know what your looking at, i use this more than my boost gauge now, it will tell you how to do it in the manual posted below.

What i would do is start with the Set at about 50% (set is wastegate duty) and the gain at 0 or the lowest it will go. Then put your start boost at about 12psi. Start boost is when the control takes control, ive never worked out why they say to put the start boost close to your desired boost, i always seem to spike that way.

Now you'll probably hit around 13-15psi i reckon for this, then just adjust the Set boost upwards and see what it spikes to. You might find it doesnt spool that quick, in this case raise the start boost up.

For me the gain did nothing apart from causing my boost to fluctuate. If your boost does go up and down along the rev range then play with the gain, if it doesnt leave it at the lowest setting.

I find the only two i play with is the set and the start boost.


My settings are:

High boost:
Set: 83%
Start Boost: 14.5psi
Gain: 5% (the lowest)
Warning 24psi
Limiter: 4%

This gives me a spike of about 23psi and holds around 12-13psi at redline.

And .pdf of the manual.

In the manual they say to have your start boost close to your desired boost but i always found it would spike like crazy at this value.

remember it would not boost past 0.8bar.....I plugged in the feed from the charge pipe onto the NC port (instead of the NO port), then it would boost more to 1.4bar.....but I still could not control the boost, turning it up and down, it still would boost the same:confused:

the NC port was for an external wastegate fitment......mega confused:confused:

I simply put this down to all the other issues on the car, but for something so simple, I just could not control the boost

hopefully Bill can get this working. Pissed off for something so simple that I could not get it to work properly

I dont think so.

Well thats what my print outs all say, one from Jabba and the other from JKM in portsmouth. Both read the same give or take so please dont just jump to conclusions about me or my car. You havent seen my print outs or my car therefore you dont know what the exact spec of it is. And to be honest i dont realy care what people think as i have nothing to prove.

Is it just me or are people on this forum becoming increasingly hostile and unwelcoming??

not at all:)

from being on here and seeing a multitude of figures, we know what is realistic and what is some what above normal and beyond the turbo's capabilities

if it is putting out that much, then I would not say much for the longevity of your turbo....

323nm but not 323lbs/ft, i just cant see that being pssible sorry.

The print out shows 437nm, i can see exactly what you are saying though, i have to say i didnt beleive it until i had the second rolling road test done.

So far the car has been like this for 2-3 years and the turbo, i am told by Portsmouth Audi, is in great condition with no shaft play, cracks etc. I beleive this to be down to the electronic boost controller so that the turbo isnt running at full power all of the time, thus prolonging its life?

no a boost controller does not prolong the life of the turbo, unless you are saying you have the boost turned down all the time? and then you crank it up just for RR's?
 
Any chance of putting up a pic of your dyno graph...???

Id still be worried about the rods at this torque though...but that might just be me...

Greddy Profec B2 on mine, Apexi ACVR on jonzy's and they work fine, just keep the N75 plugged in electronically and use the controller to regulate boost.

If you do hit limp mode for overboost (which my car has never) just dial down the boost. Simple.

I´ve just purchased a used Profec B controller I came across like yours, was wondering how you plumped yours instead of the N75? The drawings (actuator type)tells you to read the pressure from FPR but I find that a bit odd for the 1.8T, guessing that´s for the jap.engines.

Are you also using the COM-NO ports as Jamiebennet told he was on COM-NC ports(external wastegate setup)?

Also, what is your experience of the controller so far? good piece of kit when you´ve learned to set it up right?

Thanks.

Dragging up an old post but beginning to wonder whether it would be worth investing in a Profec for when my K03S hybrid gets properly mapped?

I need to read into these a little more yet and review JB's thread but interested in what people think for this particuar turbo application where taming the initial boost seems necessary.
 
Well i love mine, visible better results on the rollers with an EBC, but i guess it all depends on the mapper, if theyre ok with controlling the boost well with an N75 and you have no need to lower or increase boost then stay with the N75.

Main reason i went for it was due to the n75 being slow to react and causing surging and boost oscilation.
 
im looking into avcr are they easy to fit or would they need electrican to cut into wires ect:)
 
Profec B's are old news. If you can afford it go for the Apexi AVCR as it IS the best on the market. An if your pockets aint that deep then go for the Gizzmo MS-IBC at half the price of the AVCR and has the same features
 
myki are those avcr easy to install would you be intrested in fitting for me ;)
 
yeah true i wouldnt touch ecu either i want one so bad:lol:

do al ebc need wiring to ecu pal
