Mercedes vehicles have a certain amount of sophistication and class that is matched by few, but what they tend to miss is that certain amount of power that a few prospective buyers need and want in a vehicle. Of course, Mercedes may not be all too interested in changing their formula to please those buyers, but British tuners, Superchips, are. Superchips has come out with an ECU remapping for the Mercedes 350CDI as well as the E350 CDI, M350 CDI, R350 CDI, and S350 CDI.

With this ECU remapping, Superchips was able to increase the power of these sedans by 34bhp, bringing the total up to 284bhp at 3008rpm with 250bhp available from 2700-4400rpm. With this adjustment the vehicle’s torque was also increased to 642Nm at 2469rpm with a maximum gain of 80Nm at 3008rpm.

The engine modifications performed on the Mercedes E350 CDI and variants are available for models from 2009 and on and will allow for a more responsive driving experience. They can be done at any of the 80 Superchips performance centers for £445.00. THe kit is also covered by a 12 month/30,000 mile warranty.

Press release after the jump.

Press Release

Mercedes’ turbo diesel powerplants have always garnered high praise for their refinement and economy, if not for their outright pace. But now Buckingham-based performance automotive electronics expert Superchips Ltd can rectify this relative lack of urge with the launch of an ECU remap for a range of Mercedes models using the 231 bhp 350 CDi BlueEFFICIENCY engine.

Covering 350 CDi BlueEFFICIENCY variants across C / E / M / R and S-Class models, Superchips technicians have created a new ECU map for the Mercedes’ Bosch EDC17 ECU, safely removing some of the inherent performance constraints and fine tuning fuelling and turbo boost parameters. These changes have then been rigorously validated through a combination of road and chassis dyno testing.

The result of the Superchips ECU remap is a healthy increase of 34 bhp at 3008 rpm, resulting in a maximum peak power figure of up to 284 bhp (up from a measured standard power output of 250 bhp.) Importantly, there is a decent spread of driveable power, with over 250 bhp available from 2700-4400 rpm.

Impressively, given the refined nature of the Mercedes 350 CDi BlueEFFICIENCY models, the Superchips ECU remap delivers a significant boost in torque, which jumps from 587 Nm to 642 Nm at just 2469 rpm, realising a maximum gain of 80Nm at 3008 rpm.

The end result is a sharper, more exciting, more responsive driving experience, with additional reserves of urge on tap for overtaking or towing. And thanks to the extra efficiencies delivered by the Superchips ECU remap, the 350 CDi powerplant feels smoother and is just as frugal. Indeed, if the Superchips remapped version is driven in a ‘like for like’ manner against the standard 350 CDi BlueEFFICIENCY car, owners will experience noticeable fuel economy improvements due to the additional low rev torque delivered by the Superchips upgrade.

Installation of the Superchips Mercedes 350 CDi
BlueEFFICIENCY ECU remap entails customers visiting one of approximately 80 Superchips performance centres whose trained technicians can undertake the remapping procedure.

Customers can be assured that the Superchips conversion is covered by a full Customer Service Guarantee and an industry-leading 12 month / 30,000 mile supplementary vehicle warranty.

Covering 350 CDi BlueEFFICIENCY variants across C / E / M / R and S-Class models produced from June 2009 onwards, the Superchips ECU remap is available now both directly from Superchips and its UK dealer network, priced at £445.00 including installation and VAT.

I’ve been dreaming of having my own vintage Mercedes, but I know I won’t able to find one and also it’ll be expensive.

Yes, I do agree with the first paragraph of this article. With its class and sophistication no wonder why Mercedes is always been in the top class of all vehicles. For a responsive and unique driving experience, why don’t you try this new Mercedes 350 Cdi?

We have to check it out its efficiency otherwise it will be a great disappointment to all Mercedes fans. On its greater improvement for fuel, I agreed on the posters that we need to test it to experience its smoothness.

Wow! its sounds so cool! 350 CDi BlueEFFICIENCY would definitely makes miracle when attached on the car. Most probably I do believe on their promise for making this car sharper, more exciting and responsive driving experience.

Just like any brand of Mercedes they always come up with more powerful and wonderful designs! BTW, the Mercedes e-class will release a v12 technology.

Well they managed to make changes without ruining the look, but where is the MPS version?

For someone who lived in France, Canada and the US, I’d say it really struck me. In North America non-import brands stay in the price ranges of "generalist" brands like Renault, Peugeot, Opel up to the luxury "executive" cars, but when you look at German cars, wow.

Why are Mercedes and Audi the only one who also make e and BlueEFFICIENCY models of petrol cars?

If you really need to increase your hp then i guess there’s nothing wrong in buying.

Especially when comparing the same product, which is why it must mostly be taxes and importation and adaptation costs that bump the price of German luxury cars up that much.

Well if you’re driving on the autobahn that top speed might actually be important if you ever want to get into the left lane.

They’ll have enough room in the engine compartment to add a butler’s living quarters and a small kitchen.

I don’t see the relevance of top speed in a sedan that’s designed for non-track use. It’s a frigging S-Class— do you think any of the white hairs driving it are willing to push it into triple digits anyway? I would argue that acceleration is the more important figure for everyday use, and while top speed benefits from horsepower, acceleration benefits from torque. And force-fed diesels are all about torque.

both of which are expected appointments for vehicles in this class.
