Why Customized Chip Tuning?

Factory software is left very conservative considering Euro 3/4 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 Touareg V10", "Forklift torque increase").

Advantages of our customized service:

Provides a more elastic power band by reducing turbo lag at low and mid RPMs.
Optimizes PD injection system pressure and timing.
Reduces fuel consumption through more efficient combustion.
Perfects the harmony between automatic transmission and engine torque.
Completely eliminates DPF regeneration problems.
Increases load carrying performance in commercial vehicles (Transporter, Caravelle, Multivan).
Improves lifting power and maneuver performance in forklifts.
Provides high performance settings in V10 4.9L TDI engines.
Special optimization of Dodge/Jeep CRD engines.
Optimization of Mitsubishi DI-D engines.

EDC16U31 Stage 1 and Stage 2 Differences

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 (BEW, BKD, BPC, BLE, ECE, etc.), consider the vehicle type (passenger, commercial, forklift), add the features you want (e.g., Stage 2 + DPF Off + EGR Off + PD Optimization) and send the file back to you.

Expert Advice: The EDC16U31 is an old generation ECU with a very wide application range and requires special attention. PD (Pumpe Düse) technology uses high pressure (2000+ bar), so injector and pump sensitivity is critical. Faulty injection timing can cause engine damage. V10 4.9L TDI engines are very powerful but transmission limits must be considered. In commercial vehicles (Transporter, Caravelle, Multivan), excessive torque increase can lead to transmission and differential damage. In forklift applications, hydraulic system capacity must be considered. Dodge/Jeep CRD engines have different characteristics than VAG engines. Mitsubishi DI-D engines require special attention. Early DPF systems (Euro 4) can be problematic. OnlineChipTuning offers safe performance in PD TDI, CRD, and forklift engines with EDC16U31 experience.
