Recently, I have my ECU upgrade for the SLK 200 Kompressor from MKB. All I can say upgrade really rocks, 2 thumbs up! the engine is very responsive and the pick up speed is incredible. I really felt a total difference from the stock ECU and it is worth every penny for the upgrade. It gives a boost of additional 28 HP after the upgrade. But what can I say ? The engine is alive !

They have a step 2 upgrade which involves the intercooler. Does anyone know how much improvement would the intercooler be contributing ?

From what I understand. the ECU upgrade must include the digital M.B. signature to avoid loosing the warantee.
When an ECU upgrade is performed, the M.B. digital signature is extracted from the original ECU and then used with the modficated ECU.
Do you know if they did that.

Yes, I have been asking that question quite alot with respect to tuning the SLK 200.

Is your warranty still valid?

How much torque improvement did it give you?

Any improvement on your 0-60mph (0-100kms) ?

Hi I have included the response from MKB on their engine upgrades for the SLK, it seems that they add some hardware to the chip?

Has your warranty expired after the upgrade? Could *diagnose pick it up?

Message from MKB:
"You order the parts from MKB and them install at your local DaimlerChrysler dealer.

The MKB 27121 also includes the ECU modification. Means, you have to send the ECU to Germany. If you make a trip to Germany,

you can bring the ECU to our workshop, we modify it (which takes something about one hour) and after that you can take it with

you again.

The modification is not detectable by the Stardiagnose of Mercedes-Benz, because they only can engage in the software of the ECU.

But we change the hardware of the ECU, for which you need a special processor."

Isn't that what "Powerchip", who is a new sponsor for this forum, does? They are located in Santa Monica, CA so you wouldn't have to send the ECU out of the country. In fact, Mazeeka, they should be very close to you.

Taken from their ad:

Powerchip specializes in performance software tuning to improve horsepower, torque and drivability for European vehicles. Reprogramming the existing engine management system allows for routine servicing, is emissions compliant and remains undetectable to any diagnostics analysis; which means that a new car warranty is not be affected. Software upgrades can be customized to suit verious other modifications, to give you the best performance in all situations. Based in Santa Monica, California, Powerchip is the premiere Mercedes-Benz software tuning specialists.

I have called them, they are in the finale stages. They acually sugested to use my car for testing and ofer me a discounted price.
I seem to like this company in San diego MB WERK
THEY SEEM TO BE A M.B. EXSLUSIVE SERVISE CENTER.
IN FACT CARLSSON RECOMENDED THEM TO when i contacted them,
http://mbwerks.com/
they are just about two weeks from finishing the ECU.
You should call them for you self and Juan I think will explain the whole thing about M.B. digital sinature and the prcedure.

Just guessing, but I'd suspect that the good results from the blown version relate to pressure control, and will not be so profound in the normally aspirated ones. I'd be happy to be found wrong, though!

Here is a reply I got from some tuning "specialists"?? I found in SA. Any1 know of a "tuning-concept" in germany or bought any products from them?

I would be interested (as well) to hear from any other South Africans on the forum about this subject...

message from Tuning Concept in SA:
"Hi,

As explained only the affected maps are changed, the rest of the contents of the ECU is left as original.

It has been specifically designed for the R171 on a rolling road dynanometer.

The after power will be 133kw/270nm

Rgds,

Preggie

Have you dyno tested the acclaimed power surge?

Because ECU's for most cars do not work as promised. Especially for MB's that use a kompressor. They're totally fake, and sometimes owners "think" they feel a power difference, when in fact there is none.

Shinigami,

I asked them about the dyno testing as per your post. Their answer was : "If required we can arrange for it to be dynoed before and after - bear in mind that all the figures quoted are at the flywheel at the coast."

Does anyone know what exactly that means?

I think it means that they're testing wheel HP, not crank HP. Generally, when manufacturers display HP numbers for cars, those numbers are at the crank (in the engine). But by the time the power is diverted to the the rear wheels (through the axle, gearbox, etc), you lose anywhere from 20-40% of the power. So your car at the wheels probably was pushing 130hp, and with the mod, is pushing 150.

This is why they would need to do the numbers before, and after, because if they gave you the 'after' number now, you would be like "oh my god, I LOST almost 20 HP!!! WTF".

Hope this explains it [;)]

btw: I personally don't know how reliable power chips etc are, the reports are always very conflicting from one person to another. I do remember it being the general consensus that these chips don't work on the old SLK. A pulley upgrade is a much better way to get power. And many people who do install these chips on their cars "think" they can feel a difference, but in most instances, the human perception is wrong. It's like adding a louder exhaust. You can hear more noise, so you think your car is more powerful, faster, etc...

I had a pulley upgrade on my old SLK which upped power from 199hp (193 stock, but I had a Brabus exhaust and stuff like that) to 227hp. I remember taking my car after this mod, and whilst I wasn't expecting much, was surprised to feel the power rush in at approximatel 2k rpm (usually I would begin to feel the supercharger at 3k rpm) and I really did feel a pleasant push from my car bolting me across the street [:D]

There was a definitive increase in power, and I could feel it. Not only that, but top speed increased from approximatel 240 to 250kmh (I know, as I tried it before and after).

I assume at the coast meaning at sea level right?

They do offer a pulley upgrade as well called the SLK 200 evo with a top speed of 243km/h and 0-100 km/h dash at 6.9 seconds (originally 7.9 seconds)

But that may mean my warranty is void right?

Whilst I am cynical about some mods and appreciate others more I cant see how a 200 can be a 55 with some software.

Ask anyone. It takes cubic inches to give satisfaction. [:D]
