I'm considering doing the chip tuning to my 2005 E320 CDI. And found out there's many alternatives, see table below. Long story short, I've narrowed the field down to Kleemann & Dieselpower because of the gains relative to cost. Carlsson & DMS are way too expensive. But the most interesting part is that Kleemann & Dieselpower are one of the same! Kleemann sources their KD-Box directly from Dieselpower. So then I called Dieselpower on how they achieved 100Nm gain from 500Nm to over 600Nm. They did it by optimizing the fuel/timing mapping and also increasing injection pressure to near 30000psi (OEM is 23000psi). That makes me alittle nervous about boosting that fuel delivery system. Would that haunt me later in the life of this engine?

Additional note, both Kleeman and Dieselpower are developing newer units that also boosts the turbo pressure too, beyond the fuel/timing mapping and injection pressure. That is definitely more of a "wild" upgrade, gaining an additional 10%. But I'd be more concern about the risk to engine life by all three parameters being bumped up, esp. the turbo pressure.

 

Kosher Benz posted a photo of the Kleemann box sometime back and it looks very different from the Carlsson (the Carlsson box looks more like the Diesel Power box). The Kleemann box has 6 twin terminals (may be 7 as I am going by the photo) while the other two has 2 or 3. From what I read there is no pressure increase for the Carlsson. Kleemann boosts both the fuel & pressure.

There is another one you should look at and that is a Canadian firm with TUV certification. Go to amimotorsports.com and see for yourself. Bully Dog does one for the VW TDi but I am unsure if they do anything for MB.

Go to xtremediesel.com and check that out.

 

Are these choices that you are considering boxes that you "plug & play?"

Have you considered going the 'hardwired' route?
Seems to me that before I did my '99 E-300 DT, there was more
gain to be had going the permanently hardwired way.

Should you choose to go the better way, contact Oliver and Speedtuning and see what he has to say.
You'll not be sorry!

 

Yeah, I'll agree with the above poster - - the tuning boxes are Mickey Mouse solutions for turbodiesels. Chipping or re-flashing is a comprehensive solution.

I've got a socketed ECU board in my 1999 diesel. I've got OE chips, STusa chips and RocketChip and can switch between programs. I really haven't tracked what's available for the newest cars and can't make a recommendation.

You are lucky to have a 1999. Warranty is always a concern for me and the tuning box route is the best. If there is a check engine code or any other code I can always unplug the box and see if the code goes away. Not possible with a reflashing.

Insurance is another thing. If the car is totalled you can remove the box before a busy body inspects the remnants.

 

Excellent idea, one that I never thought of.

It is wonderful what other individuals can and do come up with. That's why I love these forums.

When you did yours', how did you do it?
Did you run a circuit connection off the board to the outside of the stock computer box, or do
you have to remove that particular box and go inside each time you want to change chips?
I know that when I first took my E-300 DT to the local turkey near here in Chino
Hills CA, and he took my stock box out, I was able to see what was going on.
Did you do all that fine soldering that is required yourself?
Good for you if you did. My old eyes cannot see well enough to be able to do that myself.
Turned out that he did NOT have the T.I. chip that he needed to program and install, and it took him more than a month to get one, and then he 'stood me up' for our appointment to change mine after I had driven over forty miles to his place, and I then went with Oliver.
Old "what's his name" representing UPsolute actually did me a really big favor!
And I was a repeat customer too, having used him before for my TDI.
You would have thought that this fool would have learned by that mistake, but I did not then know of many others who did the work for the MBZ diesels.
One wonders sometimes how some of these guys stay in business.
Some of them act like real prima donnas and are truly too independent.
This is a sideline for this college instructor, so . . Oh well!

Which 'chip' do you favor for your W-210. In other words, which one do you run most of the time?

I can also understand why these people that have newer machines still under
factory warranties are afraid to change the factory computer settings.
With expensive to repair or replace components, one must
be considerate unless they have truly 'deep pockets.'

Thanks for the really informative information.

BTW, be sure to read: http://mercedesshop.com/shopforum/sh....php?p=1493607 first.
I did not, and there are many fine pointers there to be sure.

 

Any one make a chip for a 1993 2.5l turbo diesel benz?

Thanks,

I'd say almost certainly. That's a 30% increase. If the car could safely handle near 30k PSI for the long-term, don't you think that's what it would have from the factory?

 

If you pop on over to the GL board, you'll see one reason why we might not want to further the boost on diesels as our GL320's have been experiencing turbo hoses (I believe the intercooler hose to be specific) popping off. Quite disconcerting in the hills of Colorado with big semi-tractor-trailer trucks running up on you at 85mph. So perhaps the block could take that extra boost but what other components have to put up with it as well?

 

I'm VERY happy with my Renntech CDI tuning on my '05.. It's not over kill, and my fuel milage has actually gotten better... I get close to 40 (at time over 40) on the highway at 65mph..

I'm running 15 sec 1/4 miles and 0-60 in about 6.7..

the Dyno chart is below

Please share your Renntech source with us. Is it a tuning box? How much?

 

I think the Bluetec V-6 engines come with 29,000 psi injectors.
