Why Customized Chip Tuning?

Factory software is left very conservative considering Euro 5/6 emission standards, all types of fuel quality, harsh climate conditions, and Mercedes luxury vehicle comfort standards. OnlineChipTuning shapes the file you read from your vehicle according to your requests (for example: "DPF delete", "AdBlue OFF", "Luxury SUV optimization for ML-Class", "Commercial load carrying for Sprinter").

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 7G-Tronic and 7G-Tronic Plus automatic transmission and engine torque.
Completely eliminates BlueTEC/AdBlue system errors and regeneration (DPF Regen) problems.
Provides cylinder balance optimization in V6 OM642 engines.
Optimizes torque distribution in 4MATIC 4x4 system luxury SUVs.
Makes adjustments considering air suspension (AIRMATIC) and comfort systems.
Maintains perfect comfort-performance balance in flagship models like S-Class.
Increases load carrying performance in Sprinter commercial vehicles.

EDC17CP46 Stage 1 and Stage 2 Differences

Customized Stage 1

Power achieved only through software without any part replacement on the vehicle. DPF, EGR, and BlueTEC/AdBlue remain in original condition. Safe performance increase is targeted while maintaining Mercedes luxury vehicle comfort without shortening engine life.

Safe & Stable Power/Torque Increase (+30-60 HP)
V6 Turbo System Optimization
Maintaining Luxury Vehicle Comfort Balance
Emission Systems Active

Customized Stage 2

Specific to vehicles with modifications such as DPF Delete, EGR Off, BlueTEC/AdBlue Off, and/or performance exhaust system. Maximum performance is unlocked by freeing the engine from all emission restrictions.

Expert Advice: The EDC17CP46 is a sensitive ECU used in Mercedes-Benz premium models and requires special attention. The OM642 3.0L V6 CDI engine is one of Mercedes' most successful V6 diesel engines; when properly optimized, it is both powerful and durable. In V6 engines, cylinder balancing is crucial; faulty adjustment puts excessive load on one cylinder group. Faulty rail pressure and injection timing can cause injector and high-pressure pump damage. In Mercedes luxury vehicles, AIRMATIC air suspension system can be affected by torque increase; compatible adjustment is required. Incorrect cancellation of BlueTEC/AdBlue system (especially Euro 6 models) triggers limp mode. In 7G-Tronic Plus automatic transmissions, excessive torque increase can lead to transmission damage. In 4MATIC 4x4 system luxury SUVs (ML, GL, GLK), unbalanced torque distribution adjustment can cause differential and transmission damage. In flagship models like S-Class, comfort systems (air suspension, sound insulation) can be affected by torque increase. In Sprinter commercial vehicles, excessive torque increase can lead to transmission and differential damage.
