Buckingham, United Kingdom, 2nd August 2010
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.
Superchips – don’t compromise, optimise.
