It monitors or "intercepts" fuel, pressure, etc. and as you say "tricks" the ECU to increase the turbo boost. I like it quite a bit, but it did take a bit to get it to "settle" in. After 500 miles I really noticed a nice increase in fuel economy. In terms of torque and responsiveness nice increases as well. I have mine on 4 I was wrong Boulder -- I thought it was on 5, but I started on 3 and moved to 4. I am happy where it is -- I imagine 6 and 7 increase a lot of power, but I am leary of doing damage to car even if MB dealer installed and warrantied it.

I'm still surprised that I'm getting 500 miles per tank or so in mixed driving and it's 18 gallons to top it off. It's nice after getting 13MPG and about 200 miles per tank in the Rover this replaces.

Yeah I have my S550 benched I really want to drive it, but its MPG is horrid. The diesel is a lot of fun right now, and the MPG is tremendous. You happy with the stock setting on the KD-Box or are you going to move it up a notch?

Too bad the W221 S320 CDI is not available in the US. I would own one if so.

I've got 300 miles with the Kleemann KD box installed. Regrettably, I have exhibited childish behavior and have used way too much throttle to get a reliable before and after MPG comparison. I did have one 40 miles stretch of road today and the car averaged 38.8MPG at 70. It seems to get about 2MPG better as mentioned above by C5DRVR.
Around town to 1500 RPMS it feels like it pulls maybe 5-10% stronger. Nothing huge, it just runs a little crisper. Phillfna described it as a cure for a mild cold and I think that is a pretty good description.
I was on about 200 miles of 2 lane roads today. The improvement in passing power is huge. Nice 60-90MPH roll on. I wouldn't be surprised if it would run dead even with my wife's SL550. Big improvement and I love turbo whoosh passing cars.
I'm not sure I buy the whole "learning" thing that MB pitches about ECU's. Who cares? The box is simple and a keeper.

Not me. I think the S class deserves the most refined "velvet fist" powertrains available and that's what it has. The diesel it out of character with the S. I view the E as being much more practical so the practicality of the diesel fits better.
I drove an ML Bluetec and I think the motor fits well there. I do think the KD box for an ML would be a huge improvement. With the ML's extra pounds and larger hole in the wind the KD would be a nice add.

I guess I don't see how richening the mixture improves the mileage. Seems counterintuitive. I could see if the box adjusted the timing to make more power in violation of an emmisions requirement that Mercedes was required to meet. Which is my point why wouldn't Mercedes tune the injection software to give the improved mileage?

The reduced fuel does help emissions but the diesels I've run through strict emissions in Colorado still pass with ease. MB has them tuned for low emissions. This is a whole different topic.
The tweaks are common with over the road trucks much to the chagrin of the EPA.

It's similar to getting the Air to Fuel ratio just right in a gas motor. Or, setting gas engine ignition at optimum timing. Remember in the early emissions days when you could advance a distributor and pick up power and mileage? Motors can be tweaked for low end torque, max HP, cleaner and so on.

Taken to the extremes the government will install speed detection devices in all new cars. Every time you hit 100 mph $100.00 will immediately be debited to your bank account by Uncle Sam. Imagine doing it 10 times on the highway and you are out of pocket $1,000.00. The deficit will be erased and a lot of Americans go bankrupt.

Yes it is adjustable, and it is a newer box. We are required to do emissions testing in certain counties here. It passed emissions test with box. They do the scan code and the ppm test here.

And that is the way emission control should be everywhere.

We are for the time being lucky with only the visual testing. No black smoke you pass. If there is black smoke it has to last for under 15 seconds in any minute or so. In other words if you pick a testing station with either a friendly or myopic mechanic you pass. Every time.
And that is the way emission control should be everywhere.

I don't think urea will be the future - I am personally not interested in the technology, but I am glad they are researching cleaner emissions and are able to meet stringent requirements even using urea injection. I think in a few years we will see that go away and will have more advanced exhaust and direct injection technology that will get more MPG and power at the same time reducing emissions.

CO2 caused climate change vs Bigfoot
I also agree w/ the sentiment of the last few posts. I bought the diesel and started making batches of biodiesel from waste vegetable oil b/c I thought it was a good "green" thing to do. It was a fun project/hobby, but is very time consuming. A local farmer mixes in biodiesel w/ the ultra low sulfur diesel in all his tractors b/c the biodiesel has better lubricity (and I guess the old diesel w/ sulfur isn't available to him anymore).
Anyways, to get back on topic, I recently contemplated buying a new Jetta TDI b/c I heard you could get 60+mpg! I am seriously considering the new Prius hybrid. Since I drive a lot, I should really do more to emit fewer carbon emissions.
Here is an interesting article for Boulder GT3--if you don't drive your gas guzzlers too much, don't feel so bad about it.

The author of the article is kind of kidding, but it the point he makes is valid.

I just bought an E320 CDI for the better mileage and torque, like a lot of people do. As for this "carbon foot print" stuff, go take a look at a book entitled "The Deniers: The World Renowned Scientists Who Stood Up Against Global Warming Hysteria, Political Persecution, and Fraud**And those who are too fearful to do so" by a Canadian anti-nuke advocate and environmentalist and you will see that the Obama/Gore/NYT-driven anti-CO2 hysteria is, at best, unfounded and unsubtantiated and, at worst, a horrible distortion of science.
Drive a high mpg car to save money and petroleum, but do not kid yourself, you are not saving the planet or preventing global warming (even if it exists).
Which makes more sense? Definitely Bigfoot.

Really enjoyed reading about everybody's experience with the MB CDI. I'm still stuck in my time capsule with my '83 4 speed manual 
240D. This is my first diesel benz and I'm honestly hooked. My next Benz will definitely be an '05 or '06 CDI!!
