Citroen C4 2.0 HDI 163 Stage 1 Remap (190 BHP | 420 Nm)

The Citroen C4 equipped with the 2.0 HDI 163BHP engine is a delight to drive, and it offers even more with a Stage 1 software upgrade. The engine control unit for the Euro 5 DW10CTED4 16v motor is the Delphi DCM3.5. This ECU type is relatively complex, featuring some standard tuning protection within its software. Therefore, it’s crucial to work with a tuner who is well-versed in the ECU’s torque model structure. At HDI Tuning, we excel in HDI engine remapping and possess the most sophisticated remapped software for the DCM3.5 ECU.
Implementing the Citroen C4 2.0 HDI 163 Stage 1 remap results in an impressive 190BHP and a significant torque boost to 420Nm. The torque is delivered smoothly and consistently, enhancing the driving experience significantly.

Our HDI Tuning remap offers a considerable torque increase compared to other tuning companies. This is due to our exhaustive development efforts in unlocking the ECU’s ‘anti-tune protection’ and bypassing all factory-imposed torque limits. While the torque increase is substantial, it remains safe for both manual and automatic transmissions. We also provide a reduced torque remap option for automatic vehicles for added safety.

We don’t provide a postal remap service for this ECU. Although it’s straightforward to program via OBD, bench programming is more involved. Therefore, we recommend keeping the ECU installed and programming over OBD. For those interested in DIY programming, our Dimsport MyGenius tool is available in our webshop, offering easy OBD port programming from within your vehicle.

Citroen C4 2.0 HDI 163 Stage 2 Remap with Performance Exhaust (210 BHP | 440 Nm)

The Stage 2 remap for the Citroen C4 2.0 HDI 163 engine was designed to run with an intercooler upgrade, and a free-flowing straight through style exhaust system. This remap delivers some extra top end power for those looking for that little bit extra. The exhaust work is important for this higher power remap, you likely won’t achieve the full power of this stage 2 remap without the additional exhaust work. It’s an option to increase the exhaust bore from the DPF onwards or to use a sports DPF and this will keep the vehicle road legal. With 440Nm of torque and 210+ BHP you’re going to notice a big performance gain when running this remap.

Programming Methods – OBD2

The Delphi DCM 3.5 ECU is fast and reliable to program directly over OBD, there is no need to remove the ECU.

Programming via OBD Delphi DCM3.5

  • Obtain a suitable programming tool; we recommend to use Dimsport MyGenius, you can also use Kess V2.
  • Install the tool to a reliable laptop.
  • Connect to the OBD port of your car, make sure you have backup chargers to the vehicle battery and the laptop battery.
  • ID the ECU and then take a read of the ECUs flash memory.
  • Email the software to along with a description of the remap you require.
  • Send payment through our webshop.
  • We will modify the software and send back to you. This normally takes less than 2 to 3 hours during work days.
