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->ke373 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->ke187 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

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.
