Why Customized Chip Tuning?

Factory software is left very conservative considering Euro 6d emission standards, all types of fuel quality, AdBlue system, and harsh climate conditions. OnlineChipTuning shapes the file you read from your vehicle according to your requests (for example: "DPF delete", "AdBlue OFF", "EGR off", "Commercial optimization for Rifter").

Advantages of our customized service:

Provides a more elastic power band by reducing turbo lag at low and mid RPMs.
Removes Vmax speed limiters.
Reduces fuel consumption through more efficient combustion and emission system removal.
Perfects the harmony between automatic and manual transmission and engine torque.
Completely eliminates regeneration (DPF Regen) and AdBlue problems.
Optimizes DV5R/YH01 family (Euro 6d) characters of PSA Group new generation 1.5L BlueHDi engines.
Removes restrictions imposed by SCR/AdBlue system.
Increases load carrying performance in commercial vehicles (Berlingo, Jumpy, SpaceTourer, Expert, Partner, Rifter, Combo, Proace City).
Increases performance in new generation lightweight engines (1.5L DV5R family) while maintaining efficiency.

MD1CS003 Stage 1 and Stage 2 Differences

Expert Advice: The MD1CS003 is the most advanced ECU used in PSA Group's new generation 1.5L BlueHDi engines and requires special attention. The 1.5L DV5R engine family is a lighter, more compact and efficient engine family replacing the 1.6L DV6F. BlueHDi technology is Euro 6d emission compliant and includes AdBlue/SCR system. PSA Group's DV5R engine family (RC/RD/RE/RCE) is reliable but has different versions; correct version identification is important. The YH01 engine code is an Opel-PSA joint development engine. Faulty rail pressure and injection timing can cause injector and high-pressure pump damage. Incorrect cancellation of AdBlue/SCR system triggers limp mode. DPF regeneration causes problems especially in city use. Euro 6d engines require more sensitive control than Euro 6. New generation 1.5L engines are lightweight and compact; excessive torque increase can cause structural stress. In automatic transmission models, excessive torque increase can lead to clutch problems. In commercial vehicles (Berlingo, Jumpy, SpaceTourer, Expert, Partner, Rifter, Combo, Proace City), excessive torque increase can lead to transmission and differential damage. OnlineChipTuning offers safe performance in new generation 1.5L BlueHDi engines with MD1CS003 experience.
