Mercedes C 350 CDi BlueEFFICIENCY by Superchips

The British tuners at Superchips have just released a new ECU remap for the Mercedes C 350 CDi BlueEFFICIENCY, which adds 34 bhp and 80 Nm to the power of the engine unit. Covering 350 CDi BlueEFFICIENCY variants across C / E / M / R and S-Klasse models, the ECU remap from Superchips has been validated by road and chassis dyno testing.

As said, the result of the Superchips ECU remap is an 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.)

There is also a “decent spread of driveable power,” as the tuners say, with over 250 bhp available from 2700-4400 rpm. The remap for the Mercedes C 350 CDi BlueEFFICIENCY model delivers a significant boost in torque, which jumps from 587 Nm to 642 Nm at just 2469 rpm, which leads to a maximum gain of 80 Nm 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,” a company statement reads.

The ECU remap is available for GBP 445 (including installation and VAT) and covers models produced from June 2009 onwards.
