Hey everyone,
I've been considering a newer model E class diesel. I love my E300, just redid the headgasket, cooling system, etc. but I'm wanting some more power and just something newer in general.

I'm reluctant to go with anything newer than a 2006 CDI because I like to modify my cars and play with the exhaust systems. Whatever I get will have a 3" straight pipe exhaust with just a muffler at the end. My understanding is that if I install straight pipes on a Blue Tec it will throw all sorts of codes. Is anyone aware of a tuning program that will eliminate any throwing of codes if I eliminate the emissions controls on a Blue Tec?

Think most Blue TEC models have the urea injection and if the computer doesn't like what it sees with the exhaust, it disables the engine after 20 starts. See this post.
Maybe easier to play with the fuel rail pressure with a tuner box. Some have good results going that route.

EdzBenz

Thanks for the response and post DGI. One of the reasons I will want to reprogram the computer is to eliminate any and all need to replace the urea injection system when something fails. My plan to remap the computer would be at the point I need to replace a cataylst or sensor or whatever in the exhaust system.

I could be wrong but I think that DEF (urea) only arrived in the US (in passengers cars) in '09.I'm pretty sure that M-Bs from 2008 and older don't feature it...here,at least.I'm 99% certain that DEF first appeared on the North American E Class in 2011.

I bought a large 2.5 gallon jug of urea today in Canadian Tire for a friend of mine with a 2011 GL 320 (maybe 350?) for CD$25. This works out to be $2.38 per liter which is way more expensive than diesel fuel in Toronto (today's price $1.20 per liter). Does anyone know how much the DEF cost over say, 10,000 miles?

listerone

I have limited "real world" experience with DEF,never having run low.But my extensive reading on the subject suggests the following:

With "normal" driving a tankful of DEF (about 6 to 7 gallons) lasts somewhere around 10,000 miles.My hunch is that those with a lead foot,for example,get fewer miles.I recently bought a 2.5 gallon jug at a US Walmart for $12 US.If you guys have Walmart up there DEF would probably be similiarly priced.

I just got an E350 BlueTEC (W212) yesterday and started to look around for a tuning chip. So far I've found the following:

Brabus ECO PowerXtra ($1k+)
Racechip / Raceship Pro ($170+)
Pro Bitz ($160+)
Kleeman KD / Diesel Power ($650+)
TMC Motorsport ($477+)
DTK Digital ($577+)

I haven't been able to find many reviews on any of them. Many are mixed reviews and few with dyno results. Also, there seems to be some discussion in the quality of diesel fuel in the US versus the rest of the world. The other option is to go with an ECU remap and dyno tune along the lines of a RENNTech tune but while you may get dramatically increased performance you may not get an MPG improvement hence "your mileage may vary".

Any thoughts?

If you like tuning and your used to the older stuff stay far away from the current generation diesels. Nothing is cheap on them, and not much can be done. The whole point of the modern diesel is to be clean burning, if you start removing those systems why not stick with the older versions that don't have them in the first place? The inline motors were still very easy to tune (2005 E320), after that the V6 gets complicated and few people have tuned them. The bluetecs get very complicated and even fewer have played with them...I find the bluetecs use about 10L every service (2.5 gallons per 10k miles).
I honestly think if you get a 2005-6 e320 you'll find the power is plenty, it has a good amount more the the older diesels!

I was qouted $2800 just for Brabus D6 S to be shipped to be without install

Still looking at options on what to install on the w221 bluetec.

At this point racechip seems to be the best bang for the buck option.

Have you tried Eurocharged, I believe they have tuned a few of these

EdzBenz

My E300 currently has a Powerchip ECU flash. I like it. Gave my car a little extra pep that it needed.
I think if I were to get a CDI or Bluetech I would go with the Kleeman KD Box. Or, I would call the rep at Powerchip to see what they offer. An ECU reflash can also remove any error codes if you decide to make any mods to the engine, exhaust, etc.

EdzBenz

I don't really understand why you are bashing me, newbie. I was able to eliminate the EGR function on my E300 via a reporgram of the ECU. This thread was started to inquire if any forum members have done emissions control reprogramming via the ECU to one of their newer diesels with success.

DubVBenz

Ed, ignore the troll, but I'd be interested if you found any solution, so please keep us all posted.

isstay

Remapping can be done on newest diesels and you can change so many parameters and delete some. In fact they are able to break latest protection on newest Bosch edc17 ecu with tuning protection 10.

Any idea how this can apply to us? I know there are forums out there for hacking and modifying custom ECU files, but the OM642 seems either too expensive/rare for that community to have actually done anything for it. I've seen plenty of the files for the 2 Liter Diesel MB sells though..

Plutoe

This can't be done and still meet the current emissions standards for "on the road vehicles" plus voids all known mfg warranty's!!

EdzBenz

I reside in the state of Illinois. Diesel passenger vehicles are exempt from emissions testing.
I'm not interseted in warranties. I DIY and have a good indy.

EdzBenz

I'd give Speedtuning a call to see if they have come up with a remap. I see on their website that they have a tuning program for the CDI and the V6. Maybe they have something for the newer engines too. http://www.speedtuningusa.com/products/mb.htm

Whargoul

Being exempt from testing does not make you exempt from the law.

Is it legal to speed when a cop isn't pointing a LIDAR at you?

RenegadeEngr

How does this pertain to the Technical Discussion of this Topic?
There are plenty of other forums for Morality and Interpretations of Law.

Whargoul

It proves that his point is completely invalid.

T.H.Carrera

Ok so I tried Speedbuster/tmc motorsport and DTUK. First one is rubbish and not noticeable at all. When cranked up it makes the engine behave erratically.

DTUK works awesome and worth the money. This engine has so much potential which is unleashed by DTUK. Got the DTUK through Andrew.

I use DTUK with map 3 and planning on going to plus 10% soon.

I am loving this tune on my s350.

DubVBenz

Cran,

It proves you don't have anything useful to introduce to this discussion. How soon before this name is banned too?

T.H.Carrera

Alright guys, its that time ! Gonna be trading the car in for a CLS and thus have to let go of this Diesel Piggy back tuner chip. Will be listing it in classified but wanted to give a heads up before I do that.

It is us DTUK Multichannel unit:
http://www.diesel-performance.co.uk/...-cdi-v6-235-ps

Letting it go for $450 shipped.

PM in case you have questions.

EdzBenz

Looks like a nice program. Thanks for posting the info. Now I just need a newer diesel!
