Why Customized Chip Tuning?

Factory software is left very conservative considering Euro 5/6 emission standards, all types of fuel quality, and harsh climate conditions. OnlineChipTuning shapes the file you read from your vehicle according to your requests (for example: "DPF delete", "EGR off", "Performance optimization for Golf GTD").

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 transmission (DSG) and engine torque.
Completely eliminates regeneration (DPF Regen) problems.
Optimizes CR (Common Rail) characters of VAG Group TDI engines.
Increases load carrying performance in commercial vehicles (Caddy, Crafter).
Provides high performance settings in sports models (GTD, RS).

Custom File Preparation Process for Your Vehicle

The process works with the "develop file" logic, not the "upload ready file" logic. You read and upload the original file to the system, our engineers verify the Checksum of the file, identify the engine version (CLHA, CRKB, CUNA, CUWA, etc.), consider the vehicle type (passenger, sport, commercial), add the features you want (e.g., Stage 2 + DPF Off + EGR Off + GTD Performance) and send the file back to you.

Expert Advice: The EDC17C64 is a common ECU used in VAG Group's TDI engines between 2006-2016 and requires special attention. VAG TDI engines are reliable but have different engine codes (CLHA, CRKB, CUNA, CUWA, CSUA, etc.), correct code identification is critical. Faulty rail pressure and injection timing can cause injector and high-pressure pump damage. DPF regeneration causes problems especially in city use. In DSG transmission models, excessive torque increase can lead to clutch problems. Sports models like GTD and RS have higher power potential but transmission limits must be considered. In commercial vehicles (Caddy, Crafter), excessive torque increase can lead to transmission and differential damage. In BiTDI (twin-turbo) engines, synchronization of both turbos is important. OnlineChipTuning offers safe performance in VAG TDI engines with EDC17C64 experience.
