So there are so many models of Citroen C4, C3 and Picasso nowadays we totally forgot to list the C4 Grand Picasso. Here’s an update for those who wants to see what we have available. If there are other engine variants missing just let us know by email.
Driving the Citroen C4 Grand Picasso with its 2.0 HDI 163BHP engine is already a pleasure, but it reaches new heights with our Stage 1 software enhancement. The Euro 5 DW10CTED4 16v engine uses the Delphi DCM3.5 ECU, a complex unit with a few layers of tuning protection. At HDI Tuning we specialise in HDI engine remapping, offering advanced software for the DCM3.5 ECU.
Equipped with the DW10DTED4 Euro 5 engine, the Citroen C4 Grand Picasso 2.0 HDI 150 BHP model delivers solid torque and power as standard. However, for its size, the vehicle may sometimes lack the desired punch. Interestingly, this 150BHP engine is the twin of the higher-powered 163BHP DW10CTED4, sharing the same turbo and injectors. The primary difference lies in the ECU software. This means that a straightforward remap can safely enhance power levels to the same as the gains for the more powerful 163 variant.
The Citroen C4 Grand Picasso from 2005 to 2010 is equipped with the 2.0 16v DW10BTED4 engine, originally delivering 136BHP from the factory. The HDI Tuning Stage 1 remap increases the power output significantly. This remap offers a noticeable boost in torque and better throttle response. The torque curve is smooth, progressive and constant. The remap is designed to safeguard the vehicle’s clutch and dual mass flywheel by bringing in torque gradually rather than in one big chunk.
