We calibrate the original software of your Citroen C5 II (X7) with the 2.7 V6 HDI (UHZ (DT17BTED4)) individually, for more power, more torque and sharper throttle response. Bring the car to us in Stödtlen or send us the ECU.
Choose stage and options yourself, plus an on-site appointment or sending in the ECU. One fixed price, the same for both.

Your 2.7 V6 HDI runs on the SIEMENS SID803A ECU (Siemens/Continental SID80x (PSA/Ford 1.4/1.6/2.0 HDi/TDCi: SID801/802/803/803A/804/805/806/807/807EVO) family). We read out the original software, back it up and adapt the maps individually. No off-the-shelf file.
On diesels we mainly optimise injection quantity, rail pressure and boost as well as the torque and smoke limiters, for clearly stronger pull from low revs.
The original stock software can be restored at any time.
