Tuning Question....

[55JWB]

I'm just defecting from Audi (VAG) to MB which I'm sure will only get murmours of approval here :wink:

It was very common in the VAG range to chip or remap the car via the diagnostic port on petrol and deisel cars...

Does a similar thing happen in the MB range?? I'm getting a 270 CDI and would be interested in increasing its BHP??

Many thanks

Jason

I believe Kleeman (an independant MB tuning company and one of the best out there) do an ECU remap to increase HP. Their 320CDI is well known for it's HP increase.

They do have an outlet here in the UK - you can probably find a contact no. in the MB Enthusiast mag.

Just been doing a bit of searching myself anyone know anything about www.birds.uk.com They promote the Carlsson C-Tronic system see http://www.birds.uk.com/1-PDFs/20912340270.pdf

Thanks

Look in the Mercedes enthusiast Mag, plenty of sellers. Also user JimmyTD on here sells them i think.

Newbie Question, where do I get the Merc Enthusiast Mag ???

Thanks

um - WHsmiths? its actually caled "Mercedes Enthusiast" - usually next to the BMW (hiss spit) mags etc etc

Superchips do a plug in chip for some MB models

Never heard of Kleemann but i found their site.

They also do a chip upgrade.

I'm saving for the Brabus conversion on my car

I'm pretty sure that birds in my earlier post do Kleeman also. I've also had a response from www.thor-racing.co.uk based in Coventry re the plug in box method of tuning. The Birds solution looks very professional there response to my enquiry below

Thankyou for your enquiry into Birds UK. The Carlsson C Tronic conversion is a new generation version of the software upgrade that you had on your Audi. Instead of being a 'software only' upgrade which you had loaded onto your cars engine management system, the CTronic is an 'adaptive' device which means it is actually it's own unit which plugs into the ECU. It is about the size of a palm pilot and is installed into the fuel rail system and the ECU itself, and then fixed within the ECU Housing area.

The device actually is an advanced fuel control computer which monitors and adjusts the fuel timing according to throttle demand. This is has been passed to Geman vehicle manufactuing standards (TUV) and is classed as a manufacturers product. It does not affect the warranty you have on the car in any way, and is also guaranteed for 3 years.

Fuel consumption goes down when you push the car hard, and can go up on long distance motorway driving at constant speeds. This is because the device is constantly managing the fuel system to optimise the performance of the car. With regards to servicing, this device is not detectable by main dealer diagnostic systems, and is not visible to the general engine bay area, so although it does not affect the manufacturers warranty, to keep things simple for the dealer, it also is not obvious.

Please supply your address and I will send through an information pack on this.

I have requested a pack and will post my findings

I agree with regard to the Carlson sytem.

As for the golden question??? What does it cost????

 

[55JWB]

From what I could gather from the website roughly £1,000 all in


I'm waiting for a pack in the post

Hi Jason
I fitted a "Tuning Box" to my ML270 and I can honestly say that there is a substantial increase in performance, before, my ML was a slug, now I can keep up with White Van Man! They claim 25-30% increase in power and I would say in my experience I would agree. Its made all the difference to my 2ton slug. I would definately recommend it as a cheap improvement in power. The other thing is that it is easy to fit, being a simple thing of unplugging one plug and fitting the tuning box in between. It takes half an hour of working out where to fit and 5mins to actually do it. The superchips method I think means that you have to take it to a garage to have it fitted and then the same to remove it. My thoughts were, will MB honour the warranty ??. At least with mine, I can remove it before it goes in the garage for a service, and then replace it afterwards. The other thing is that the On Board Computer thingy doesnt keep information that it has been fitted. I bought mine on ebay but there is a distributor for the UK in Westmeath in Ireland ,

Thanks for the reply good to hear from someone that uses one....

I'm seriously looking at the Carlsson one on the basis that they are almost oem :?

Taken the plunge and gone with Carlsson having it done the day I pick the car up

pity its the 22 version

Spent quite a bit of time researching and there are a few different solutions 'out of a box' as it were... here are some words of wisdom.....

Jason,


No problem, we will send you the information pack in the post.

The item mentioned below is very interesting, but does not make a lot of engineering sense. In particular the technique to increase in fuel rail pressure is not the best way to get increased performance out of the car. Basically an increase in performance on a diesel engine through usually comes from one of two methods to get more fuel into the engine. these are

1) Fuel pump pumps harder (higher pressure)
2) Fuel pump pumps for longer (duration of fuel injector).
(or indeed a combination of these two)

The first technique is the one used by most 'chipping' outfits as it is easy to develop in house, and works, at it's crudest level it is by applying more voltage to the fuel pump which makes the pump work harder at all times. The downside of higher pressure is that the componentry in the car (specifically the fuel pump) is then working outside of the manufacturers design standards, and any fault issues which may arise from the failure of the fuel pump cannot neccsarily be covered by the manufacturer. Also, as this is a crude technique, in most cases the fuel pump is working harder all the time, including when the engine is at idle, this can leave to too much fuel entering into the engine at some engine speeds when the engine is not needing additional fuel. The upside is it is cheap to manufacture a solution, and as most people are not informed buyers, does in fact satisfy most of the market.

The second and newer technique is to increase the duration of the fuel injector. This gets more fuel into the engine, and does not make the pump work harder, but for longer bursts. It also is an 'adaptive' device, which means that the increase in the fuel timing is only enabled according to when it is relevant. So when the engine is at idle, it is not increasing the fuel injector time, and it will increase the fuel duration a little, and when you push the car hard, it increases the duration of the fuel injector even more, i.e. it adapts to the way you use the throttle. The downside of this second 'duration of fuel injector' issue is that it requires much more advanced set of hardware and software controls to be developed and then manufactured, (ie. a separate computer/device) which in turn has a higher sale price. The upside being that it is classed as a manufacturer class product and does not affect the warranty on the car or engine in any way. It also often offers better overall BHP and Torque.

The issue of black smoke is consistent on all diesel engines whether upgraded or not, it is a fact of physics in the way diesel burns, so is an issue today on your car whether you upgrade or not. The note around turbo's is not valid as altering turbo settings is generally not regarded as a good idea by vehicle manufacturers.

I hope this explains the differences, and to summarise you need more fuel in to get more power and torque out; fuel pressure is QAD way of getting more fuel in but the proper way of doing it is to have a separate device which manages the whole fuel system more effectively, provided that this is within the original manufacturers design on the car.

With regards to Carlsson and where they fit in the industry, they are one of the largest Aftermarket tuners of Mercedes in the world, are in fact owned and run byt the Hartge family who have a background in BMW tuning and racing. Birds UK are the oldest business partner of both Hartge and Carlsson, we also are our own tuning manufacturer.

It is no problem at all if you have more questions, so please let me know if you would like further clarification.

55 dont you need to drive the car so you can compare the before and after???

Either way please keep us informed as i want to do similar to my E320cdi and i'm sure i could fit one of those without telling the wife

 

[55JWB]

I get to drive it there :wink:

My collegue has the exact same car so we could always pull up at the traffic lights like the Vaxhaull Nova boys, Stereo's blaring and race each other :wink:

I've made the decision and will be in the area that day so what the heck 'just do it' as a well know sports brand would say. :wink:
