EDC17CP45 ECU: Professional Chip Tuning File Service for BMW Diesel Engines
The key to performance in BMW's powerful N47D20 and N57D30 diesel engine series (X5 25d, 535d, 640d, etc.) is the EDC17CP45 ECU developed by Bosch. This advanced engine control unit manages the common rail injection system, variable geometry turbo, and emission control systems.
As OnlineChipTuning, instead of standard database files circulating on the internet, we offer custom file services prepared from scratch by our engineers according to the vehicle's current mechanical condition, fuel quality, and installed hardware (DPF Delete, EGR Off, Intercooler, etc.). By analyzing the complex injection and boost maps of the EDC17CP45 ECU, we ensure you get maximum power and torque within the engine's safe limits.
This page details the technical capacity of the EDC17CP45 ECU, supported BMW E and F Series models, and the Stage 1 and Stage 2 advantages you'll gain by submitting files through OnlineChipTuning.com.
EDC17CP45 ECU Technical Specifications and Potential
The EDC17CP45 is an engine control unit with a TriCore processor that controls high-pressure diesel injection with microsecond precision. The original file you upload to our platform is processed with professional software like WinOLS to reveal this ECU's hidden potential.
Main optimizations we offer on this ECU:
- Performance-oriented adjustment of injection quantity (IQ) and timing (SOI)
- Stable increase of Turbo Boost Pressure
- Increase of Rail Pressure (Fuel Pressure) within engine safety limits
- Improvement of Throttle Response
- Expansion of air mass (MAF) and manifold pressure (MAP) limits
Which BMW Models Feature EDC17CP45?
This ECU is common in 2.0, 3.0, and 3.5 liter diesel engines of BMW E and F chassis produced especially after 2010. The most processed models in the OnlineChipTuning file panel are:
- BMW X6-Series (E72) 40d xDrive N57D30TOP Diesel
- Alpina B3 (F30) 3.5L N55B30 Petrol
- BMW 1-Series (F20) 125d N47D20 Diesel
- BMW 3-Series GT (F34) 335d N57D30 Diesel
- BMW 4-Series (F32) 435d xDrive N57D30 Diesel
- BMW 5-Series (F10) 535d N57D30 Diesel
- BMW 6-Series (F12) 640d N57D30 Diesel
- BMW 7-Series (F01) 750d xDrive N57S Diesel
- BMW X1-Series (E84) 25d xDrive N47D20 Diesel
- BMW X3-Series (F25) 35d xDrive N57D30TOP Diesel
- BMW X5-Series (F15) 25d xDrive N47D20 Diesel
In these vehicles, the EDC17CP45 can offer incredible power increases with software (Stage 1 with +40/60 HP, +80/120 Nm), especially when combined with DPF and EGR system removal.
Why Customized Chip Tuning?
Factory software is left very tolerant 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", "AdBlue OFF", "No check engine light").
Advantages of our customized service:
- Provides a more elastic power band by reducing turbo lag at low RPMs.
- Removes Vmax (190km/h or 250km/h) speed limiters.
- Reduces fuel consumption through more efficient combustion and emission system removal.
- Perfects the harmony between transmission and engine torque.
- Completely eliminates regeneration (DPF Regen) problems.
EDC17CP45 Stage 1 and Stage 2 Differences
Power achieved only through software without any part replacement on the vehicle. DPF and EGR remain in original condition. Safe performance increase is targeted without shortening engine life.
- Safe & Stable Power/Torque Increase
- Turbo Lag Reduction
- More Responsive Throttle
- Emission Systems Active
Specific to vehicles with modifications such as DPF Delete, EGR Off, and/or bigger turbo. Maximum performance is unlocked by freeing the engine from exhaust back pressure and allowing it to breathe comfortably.
- DPF / FAP Completely Off
- EGR Valve Deleted
- Lambda / O2 Sensor Adaptation
- Maximum Torque and Horsepower
Special Solutions Offered with OnlineChipTuning
Since EDC17CP45 ECU is a diesel unit, we offer all diesel-specific emission system deletes and performance solutions:
- DPF / FAP OFF: Complete shutdown of the particulate filter system and elimination of regeneration problems.
- EGR OFF: Disabling the exhaust gas recirculation valve to allow cleaner air into the engine.
- AdBlue / SCR OFF: Cancellation of the AdBlue system and prevention of urea injection errors.
- VMAX OFF: Removal of factory speed limiter.
- Lambda / O2 Delete: Turning off the check engine light (CEL) that comes on after DPF removal.
- Swirl Flap OFF: Closing the swirl flap system in the intake manifold.
- Cold Start Noise Reduction: Reduction of diesel clatter during cold start.
- Sport Display Calibration: Updating Sport Indicators (HP/NM) on the vehicle screen according to new power.
- Start/Stop Delete: Permanent deactivation of the system.
- Hot Start Fix: Resolution of hot engine start problems.
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, add the features you want (e.g., Stage 2 + DPF Off + EGR Off + Vmax Off) and send the file back to you.
Why Us?
- 24/7 File Service: Fast turnaround time so you don't keep your customer waiting.
- Technical Support: You can get support for problems during file upload or writing stages.
- Warranty: Our software is prepared within engine protection limits (Component Protection).
- Emission Delete Expertise: We have years of experience in DPF, EGR, and AdBlue deletes.
