Citroen C5 2.0 HDI 110 Stage 1 remap (145 BHP | 320 Nm)

The Stage 1 remap for the Citroen C5 2.0 HDI 110 was designed for optimum performance and reliability on a standard vehicle with original components. Peak power will be 145 BHP and maximum torque will be increased to an exciting 320Nm. The stage 1 remap offers great performance, driveability and safer overtaking. On top of this you can expect to see economy gains of 3-5 MPG on average.

Price:

Citroen C5 2.0 HDI 110 Stage 1 + Remap (155 BHP | 360 Nm)

The Stage 1+ remap adds to the gains of the stage 1 remap and requires a straight through exhaust system upgrade. Peak power for your Citroen C5 2.0 HDI 110 will be increased to 155 BHP and the maximum torque will be increased to 360Nm.

Citroen C5 2.0 HDI 110 Stage 2 Tuning (160 BHP | 365 Nm)

The first step to running a stage 2 remap is to upgrade to a large front mounted intercooler. For this, bigger is better and you will not notice any significant lag from fitting a larger cooler but you will benefit from the cooler denser charge.

As boost will be increased, a higher reading MAP sensor must be fitted so that the ECU can regulate boost at a higher pressure, the 3.1 Bar MAP sensor uses part number 9649396580.

To help with EMP the exhaust needs to be a straight through system, 2.5 inch is best.

Most vehicles will require a new clutch or an upgraded Kevlar clutch to handle the extra torque. With 365Nm there will really be a big difference in power and torque and how it’s delivered.

Price:

Stage 3 (180 BHP | 420 Nm)

The stage 3 remap requires all of the Stage 2 upgrades, and also a turbo upgrade. The fuel pump must be upgraded to the R70 pump from a 2.2 HDI or a 3.0 BMW 530D. It’s important to use a good low mileage pump and not one that has been left standing without fuel in as the pump can corrode inside and cease, thus damaging the seals once it’s turned.

The fuel pressure sensor 1920GW must be fitted, to get the engine to run with this pins 1&2 must be swapped in the wiring loom to the sensor.

The turbo upgrade would ideally use a 52mm compressor with a VNT turbo, although a waste-gated turbo is also acceptable and easier to regulate with a mechanical boost controller.

The electronic turbo control will be de-activated in the ecu software to avoid setup complications and to allow for external regulation.

For VNT turbos the turbo can be controlled using a product called DigiBooster S. This uses electronic PID control to regulate boost with selectable strategies, a VNT turbo cannot be effectively controlled using only a ball and spring type mechanical boost controller.

A ceramic paddle clutch is required to hold the 420Nm of torque.

1800 Bar fuel pressure sensor upgrade Part 1920GW

For vehicles running the upgraded R70 fuel pump wishing to push for a little extra top end power we can increase fuel pressure slightly. The stock sensor can only go to 1500 Bar so an upgraded sensor is required with part number 1920GW. Pins 1&2 must be swapped in the wiring loom in order to start the engine and a new calibration must be added via a remap. Injector calibrations in the stock ECU software run only until 1400 Bar, we will extend using our custom calibrations to 1800 bar. We recommend to run a max of 1600 Bar even with the uprated sensor, otherwise the extra work load on the fuel pump is too much. Price:

  • £50 extra on top of remap cost – included with stage 3.

Programming Methods – OBD2

The EDC15C2 is an old ECU type and as such it’s covered by nearly all tools on the market. The best and most reliable tools to use are Kess V2 and MPPS. These tools can program directly over OBD without needing to remove the ECU. If you’re looking for an on the go flasher which can store up to 10 maps and be used when ever you choose, then we recommend using Dimsport MyGenius.

Recommended programming method:

Program over OBD using the Dimsport MyGenius standalone tool

The Dimsport MyGenius tool is the safest, easiest and most reliable way to program your ECU from home. Simply connect to the OBD port and let the tool do the work, no need to remove your ECU or bench program for most ECU types. For more information have a read here

The read and write processes both take around 1 minute for this ECU type.

How to use the online remapping service:

  • Obtain a suitable programming tool.
  • 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 remap@hdi-tuning.co.uk 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.
  • Using the same tool, ID then write to the ECU. This will overwrite the ECUs flash memory, it’s important not to interrupt the process. If you encounter any problems we can fix the ECU for you so there’s absolutely nothing to worry about.
  • Let your engine warm up and then take the car for a spin, enjoy the extra power!
