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 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 Q7", "Sport performance for Cayenne").

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 8-speed automatic transmission and V6/V8 engine torque.
Completely eliminates AdBlue/SCR system errors and regeneration (DPF Regen) problems.
Provides cylinder balance optimization in V6 and V8 engines.
Optimizes torque distribution in Quattro and 4x4 system luxury SUVs.
Makes adjustments considering air suspension and comfort systems.
Increases performance in S-Series (SQ5, Cayenne S, Macan S) models while maintaining sporty character.

EDC17CP44 Stage 1 and Stage 2 Differences

Customized Stage 1

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

Safe & Stable Power/Torque Increase (+40-80 HP)
V6/V8 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, AdBlue/SCR Off, and/or performance exhaust system. Maximum performance is unlocked by freeing the engine from all emission restrictions.

DPF / FAP Completely Off
EGR Valve Deleted
AdBlue / SCR System Off
Maximum Torque and Horsepower (+60-100 HP)

Expert Advice: The EDC17CP44 is a sensitive ECU used in premium brands and requires special attention. In V6 and V8 engines, cylinder balancing is crucial; faulty adjustment puts excessive load on one cylinder group. In 4.2L V8 TDI, twin-turbo synchronization is critical; if one turbo is overloaded, damage can occur. Faulty rail pressure and injection timing can cause injector and high-pressure pump damage. In luxury vehicles like Audi and Porsche, the air suspension system can be affected by torque increase; compatible adjustment is required. Incorrect cancellation of the AdBlue/SCR system (especially Euro 6 Touareg, A6, A7) triggers limp mode. In 8-speed automatic transmissions, excessive torque increase can lead to transmission damage. S-Series models (SQ5, Cayenne S, Macan S) have high factory power (312-385 PS); careful optimization is required. In Quattro and 4x4 system luxury SUVs, unbalanced torque distribution adjustment can cause differential and transmission damage. OnlineChipTuning offers performance while protecting engine health and luxury vehicle comfort with EDC17CP44 and premium brand experience.
