That's right, I am considering having my ML 270CDI "Chipped". The dealer reprograms the engine management system. The increase is 30 bhp (www.superchips.co.uk). Speaking to people who have had it done says that the mods cannot be detected when the system is plugged into the dealers computer. I have driven a 98' E300 turbo diesel and that baby has some serious power now. Anyone had this done?

my ml's are chipped...it didnt give me 30hp. be weary of this person, sounds like they are lying to you.

I would be more likely to believe 15-20hp tops with a software tweak. At 268 hp for an ml 430, realistically a 6-8% increase in power would be possible given proper fuel map and timing adjustments would only yield an additional 16-21 ponies. A 3.2l ml320 at 215 hp would be in the area of 13-17 hp. remember its only software.

hello, I just registered to reply to this since it seems the two above don't make any sense. They failed to read that you have a 270CDI. I would say you can pick up an easy 30 hp, if not more from a chip alone these chips usually adjust timing, fuel pressure and injector duration. I'd stay away from boxes that just crank up the pressure instead of just timing and duration as adding pressure can cause injector/high pressure fuel rail problems. I'd also run a good intake and exhaust to keep the EGTs down. If anyone questions whether you can add 125+ hp to a diesel in a programmer alone, look at www.edgeproductsinc.com or www.quadzillapower.com.

hope this helps

hey montecarlo, perhaps you are right, these gasoline guys know nothing about modern coal burners!!!! When I bought the ML the dealer said that if I wanted he could get the power increased by about 25hp more. At the time i didn't even think about it. I have done some research and everything seems to point towards this figure or thereabouts!! I will have my truck chipped at my dads garage when i go back to the UK in September, so I will report then!!

pointman

you two are made for each other. you obviously know nothing about performance tuning if you honestly think that a chip alone is going to give you 30 hp. get that thing dyno'ed before and after... and then we'll see whats what.

Swiss Nick

you're just jealous incase the diesel kills you in a race!! ha ha!!

his ML is turbo charged and chipping any forced induction engine (especially turbo) is an easy way to gain significant HP. The same goes for turbo diesels.
Maybe you're getting confused with NA (Normally Aspirated, ie non turbo / super charged) engines - in which case power gains from chipping are marginal at best.
In the turbo charged F1 race days, qualifying laps were usually done with the boost waste gate blocked off and the tiny 1600cc engines would produce over 1000BHP, but frequently only for one lap before they detonated :-) For the race proper boost was lower to provide a more modest 700BHP - all done with simple sw tweaks.

CHIP TUNING
The performance of your car is limited by the manufacturer because the car has to be able to run on petrol of very poor quality and also run for extended periods without regular service.
If you on the other hand are prepared to service your car at the specified intervals, Kleemann can enhance the cars performance and fuel efficiency.

The is an abundance of in-expensive chip tuning products and solutions on the market today, but it is far from all that deliver the promised gains in performance and driving comfort. Many can even have a harmful effect on the engine. Kleemann has spent thousands of hours developing the optimum chip tuning solution for your car.

Kleemann can improve the performance of any Mercedes-Benz model, Petrol and Diesel, turbo and normally aspirated. Kleemann develops special chip tuning solutions for Kleemann Kompressor systems and Kleemann "Stage" tuning systems.

Normally aspirated engines can be improved by as much as 10% HP and TQ, Turbo Petrol 25% and Turbo Diesel as much as 30%.

Contact your nearest Kleemann agent to discuss the chip tuning possibilities for your vehicle.

i understand that... but where did he say he is talking about a turbocharged ml?

pointman

anytime you want.

timdf

if it wasn't a 2.7 litre diesel non turbo'd engine in a vehicle as heavy as an ML would make acceleration glacial at best :-)

pointman

haha... well said. i thought we were talking about a reg. 320 or 430. if im wrong, sorry.

FYI all CDI engines are turbo charged.

Swiss Nick

The ML has two turbo diesel engine options, 2.7 and the MIGHTY 4 ltr V8 (twin turbo I think).
For your info, specs on the V8

Number of cylinders : V8
Displacement [cc] : 3996
Maximum power [hp @ rpm] : 250 @4000
Maximum torque [Nm @ rpm] : 560 @ 1700-2600

" understand that... but where did he say he is talking about a turbocharged ml?"

The Guy said he has a 270 CDI which is deisel and has a compressor hence CDI.

pointman

i missed that.

montecarlo31

ahhh...reading is the key to a post....270CDI, a quick search would yeild this is a turbo diesel. If you still think that programers can only yeild 30 percent increases check out the duramax diesels and newer cummins diesels. Turbo diesel is the way to go but too many americans don't have a clue how good they are, more power, more mpg, lasts much longer, longer service intervals etc... There are plenty of dyno sheets to show the chipped improvment of a ML400 (how I lust for one).

On Edit, CDI stands for Common Rail Direct Injection, nothing about a turbo.

pointman

take your own advice genius and try reading. i said i understood that about turbos, then i apologized. maybe you should take your advice and read before you post.
