E320 CDi mod
I have a S211 220cdi (150hp)with gt2256v, with reprogramming.
I have 191hp and 469Nm, but i have a problem, my auto transmission don´t accept more Nm´s (power).
At 2500rpm-3000rpm, it lose some power, and later ace 3000rpm continues with total force even 4500rpm.
Sorry my english it is difficult to understand

Thank´s

In program, there is torque limiter for every gear.
It limits the torque to 450nm level, gears 2->5.
Your tuner had to do some homework.

But it is not a very big problem anyway.
With orig. injectors it is so near to max amount.
~190hp is relative good result.
Bigger cooler might give little more, but is certainly good for your engine.
Rail pressure increasing till max revs gives also little more power.

Thank´s for help me.
So, can i reprograming the auto transmission for up the torque limit for 500Nm or more???
It is possible that?
The bigger cooler is good for engine, but have i ''lag'' in future??
Thank´s for help me.
You have a very good project, you have a manual transmission or a auto transmission?

There is no upper borderline for the limiters.
The line is there, where tuner puts it.
For instance, if he just rise them to 1000nm, and they don´t bother any more.
There is still a one more torque limiter left, which is needed.
Mercedes software is not easy.
If you have "right" kind of software, there are numerous of every kind of limiter limiters.
Bigger cooler does not increase turbo lag at all.
Don´t expect much more power any more with stock injectors.
Your level now is ok, good actually.
As I said, cooler and higher rail-pressure might give a more.
And if your tuner want´s there are very good tools in program to control charger vanes.
With max pulse ration map he can force the vanes more open on max power area.
That gives more air-mass through the engine, which is good during the heat stress, ...and smoke if that matters.
That map is shortly after (smokemap) boostmap.
After cooler you need bigger charger and AMG-injectors.

Hi tuikku,
AMG-injectors
ohhh... that is very expensive 
Look the map power


I have problem with auto transmission in red circule (2500rpm-3000rpm)
I will talk with my tuner.
Thanks
Thats whats known as a "dyno-queen" power curve. All show, no go.
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.
"...With "hard" chip, that engine gives ~270kw, ++600nm..."
What is "hard" chip? Is it custom tune? If so does your tuner do custom tune if I send him the ECU?
"... that engine gives ~270kw, ++600nm..."
That's over 350hp!!! WOW!!
That's a lot better than I expected out of this car

Hi Björnar.
I am closer that you might expect... in Finland.
Maybe the easiest is if you can get a decent remapping from your friend.
~270hp/+600nm is possible.
I don´t personally like at all those "tuning-boxes".
You don´t need to do anything for exhaust pipe, or cats, if they are ok.
Neither new injectors, because there are no "easy" alternative to have a bigger turbo.
And what you first need is a bigger charger and cooler.
I can send pm to you, if you need the address of injectors.

Well, seems that I have made a writing mistake...
Sorry, I am on the opposite side of this ball.
Remapping is not the problem.
Reading and writing the program from yours cars is.
Surely there must be chiptuners, who can do the job, and have the tools.
Any tuner can transmit diesel-chips from Europe and write it to you cars.
Practically all cdi-MB,s can be done via obd-port.
Reading the stock program from car takes something between 5-10min.
Remapping 15min-1hour, depends on the program.
Re-writing 2-5min.
Very often, the whole thing, under 30min.
2nd post
I think remaps can be done locally here in US?
I had my 06 E320CDI tuned by Powerchip in California.
Never had a chance for dyno to confirm horsepower but car drove well. Maybe someone else has had dyno?
my tuner reduse NM´s, but the car have now 168hp and 3XXNM, for a gt22 it is a good power

My tuner had to do some homework.

With this turbo
gt2256v
i waited 200/210hp and 430/440Nm.He redused Nm´s and he redused HP too
, why?
At 3800-4000rpm i dont have more power

The turbo, MFA, sensor temperature, and more sensor are ok, i made all test and it is ok.
Bye

You should feel a difference.
Well, you don´t and neither your tuner don´t like this.
He had to learn using WinOls.
Now he is probably using some kind of editing- program (...tuner-pro maybe), so his only chance is change the total amount of torque.
The only chance to make decent custom files, is to use WinOls.
That kind of turbo-swap program is actually quite easy to do...
There is very very good tools to control the turbo in your cars program.
Your cars ecu is similar than mine...
Maybe it is best to try some other.

My turner make very cars in Portugal, very BMW´s 335d with 350hp and 700Nm, M3 with 400hp, seat ibiza 1.9tdi(130hp) with 280hp
and more...But work in mercedes, he don´t have any mercedes with big power.
I think he is learn about mercedes, but if my ECU is a EDC16, many´s BMW´s have EDC16 too, soo i'm confused.
Thanks

I had a engine break down.
Connecting rod bearing, cyl 2, look above.
One screw was bad and don´t last.
I bought this as new, so the bad screw must be there all the time.
I heard the sound of it for a long time, but I did´t want to believe that it is even possible to have a any "building false" in MB engine.
Well, it costs new crankshaft and rod...
...And lots of work.
The other bearings were in very good shape.
So, still there is not too much torque. (~600nm)
Also clutch and flywheel were ok, no slipping.
