Yes, it a “great secret”, what the tuners do to our cars.
That’s why it is so difficult to compare,
no, it is practically impossible for common user to compare different chips.
We must only trust.
It does not seem so good, or what do you think ?


Most compares power, the bigger, the better (chip).
Personally, I don’t think so.
For me, good workmanship indicator could be for instance that tuner limits the torque/power to certain level, which technics can last.

The fact is, that technical features makes the true limits for outcoming power.
No reprogrammer can go over these limits, in real life.
There is always a common sense explanation to every power increase.
Or if not, it is not true.

Here are some graphs for Analise, box Carlsson vs MBpower chip tuned of my car...

Carlsson announced 170Hp and 390Nm but where did they go!?? (164Hp and 348Nm)

Carlsson


MBpower

Nice curves.
Especially torque-curve is good.
No peak, and max is over 2000rpm.
Max power is also “in good place”.
No smoke yet.

You had two different dyno-days.
Start levels are different.
Power increase is about same.
If the dyno tells the truth, it is an accident.
The power-difference between reference and tuned is important.

There are few percents fault always.
I am not going to explain, too many words, that I don’t know.
Maybe some “native-English” can help.

Even couple of percents difference is quite noticeable.
This my car have over hundred dynoruns.
I have had very different amount of power, with exactly same consistence.
But I think, that 190kw, might be near truth.
Everything you want between 250-270.


I mean this, when I wrote “start-level”.

Little about torque.

The chiptuning problem is, that low-end torque increases too much, easily.
More than flywheel and clutch can stand.
High low-end torque stresses technics very much.
So, it is very easy to have too much torque, and it is quite challenging to limit it without loosing max power.
But it is possible.

The highest torque is not the “evidence of good workmanship”, but the right amount of it is.
It is quite same thing about max revs.
When max power rpm,s comes clearly under 4000rpm, there is too long spraying-time or too little air-flow.
Practically, thermal stress goes up at the same time as max power rpm,s goes down.
Yes, little more power and much more smoke.
Turbo don’t like that.

“~20%-law”, is, in fact quite good.
When you compares reference-level and tuned-level.
There are exceptions, but also “common sense” explanations to them.

Different shape torque curves


Blue = stock
Red = Chiptuned
Green = Well tuned
Black = Hopefully my engine.

I have tried to “build” that kind of torque-curve to my engine.
Enough torque to low revs, but the max in quite high revs, when engine already runs more smoothly.
Controlling the boost pressure rising speed, is one “key”.
Boost pressure rising curve = low-end torque rising curve.
When boost pressure reach the max level, fuelling level do it also.

When I did the chiptune I asked to make the car similiar to the Carlsson box (first dyno) but to improve it at high rpms.
Off course it had improved in all rpm, and the car feels a lot diferent, much much better now.

Soon I will have new Intercooler and turbo, and then I will ask for different setup, better, but based on the one I have, few changes

Work two holes and threads in flange.
The other is for K-type-thermo-sensor.
-> EGT
The other for 4mm metal pipe.
-> EGP

Good luck !
Maybe you need AMG-injectors, too.
But we will see.

A good friend of mine dynoed his car (E220cdi A) yesterday.
560nm torque, but “only” nearly same power, than mine.
He has little different program, more spraying time.
It gives more torque.

It really seems, that 240D.. was right.
So, this Garrett map is quite realistic.
I need bigger charger.
And I might have found it, it is already here, in Finland.

A 2259? Don't you already have a 2359 which has a bigger turbine wheel?

Yes, exhaust side is ok.
That is not the problem.

It is compressor air flow capacity, especially under high pressure.

Problem, or problem….
GT2359 is surely a good charger.
I recommend it also to you.
Works very well, even with simple mechanical control.

Hopefully I have solved the turbo-problem.

I get Garrett 3067 VNT hybrid charger.
Turbine wheel is 1mm larger, than now.
That is ok.
Compressor wheel comes similar than this.
That is excellent to my purpose.

Tuikku,

Do you have any suggestions to soup up my 2006 E320 CDi (straight six, not Bluetec)? I do not wish to be too radical and want a daily driver which can easily be converted back to stock when it comes time to sell.

For example:

Bigger injectors.
Bigger intercooler (though I can see no room for a bigger one)
Single side exit exhaust immediately after the catalyst.
Carlsson tuning box.

Your comments please.

Forget the carlsson tuning box!! A specified chiptuning is much better

Where did you find it and what make/model of vehicle is it used on?

As LOB says, reprogramming might be the best alternative for you.
With "hard" chip, that engine gives ~270kw, ++600nm.
And works still very reliable.
It is very close to charger limit.
Bigger injectors cannot give much more.
Exhaust pipe is enough big.
Bigger cooler is always a good purchase.
If there are not any tuner there, maybe then the only alternative is sent the ECU-box here, in Europe.

Your job is only drive and enjoy and make the front wheels suffer.


Charger is originally used on Hino-diesel-engines.
Trucks.

Hi, Just wondering are the parts interchangable to the point of being able to put smaller injectors on .. say if you wanted to save the planet and some money on fuel... and does the charger have a adjustable blow of valve if so where is it.. I would like to make my cars dump louder .. I am not to bothered if it sacrifaces a few horseys

There is no such thing as a Diesel blow off valve.

Maybe boost pressure leaks “out”.
Check air hoses, and cooler.

240D.. is right.
Any extra valve in air-hoses is against diesel engine working principals.
Diesel needs air-surplus.
“Non-smoke” bases on that.

wow... Prehaps ... but you really do hear the turbo wind up and then a little vent to atmosphere I suppose it could be a leak but this car has every service stamp right up to the mileage I baught it.. and was under the belief the motor was indeed in very good shape

and when my pal was driving behind me he was saying there was allot of white/grey smoke when I had the hammer down.. I never get black smoke, or smoke at all at low speeds
and there is no venting at high speed..

its a shame its not in the design because it really is quite cool reving up next to a sti and hearing a actuall blowing off sound and then watch the jaw drop and you leave him in a cloud of diesel smoke heheh yep we are always picking on you STI drivers thats what you get for driving a road going rally car

2001 E320 Avant turbo diesel
ok I had a look under the hood and gues what I can see the valve mounted on a bracket and a actuator going to it from the turbo.. also a vacume line comes back to block off vacume nipples and on the bottom of that another vacume line goes down to a thing that looks like fish tank filter/fuel filter but instead of going some where it just has what looks like a peice of cork in it !! ??
The Valve is incrusted with oil and **** so I will steam clean it later!!

Same age engines are equal.
Only difference is program.
You can self check it here.

Same age 200cdi A = 220cdi A.
(Difference is in program)

Only real difference, that matters, is between same age 200/220 man. transmission models.
220cdi has stronger clutch/flywheel.

What´s up about LOB´s turbo-project ?

My new hybrid-charger is almost ready.
