EDC17CP42 ECU: Professional Chip Tuning File Service for PSA Group, Ford and Jaguar-Land Rover 2.2L Diesel Engines

The key to performance in Peugeot, Citroen, Ford and Jaguar-Land Rover's 2.2L HDi/TDCI/TD4 diesel engines is the EDC17CP42 ECU developed by Bosch. This advanced engine control unit precisely manages the common rail injection system, turbo management (including twin-turbo), and Euro 4/5 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, etc.). By analyzing the complex injection, boost, and emission control maps of the EDC17CP42 ECU, we ensure you get maximum power and torque within the engine's safe limits.

This page details the technical capacity of the EDC17CP42 ECU, supported models, and the Stage 1 and Stage 2 advantages you'll gain by submitting files through OnlineChipTuning.com.

EDC17CP42 ECU Technical Specifications and Potential

The EDC17CP42 is a versatile engine control unit used in a wide range of brands, precisely controlling high-pressure diesel injection (1800-2000 bar range). The original file you upload to our platform is processed with professional software like WinOLS and ECM Titanium to reveal this ECU's hidden potential.

Main optimizations we offer on this ECU:

Performance-oriented adjustment of injection quantity (IQ) and timing (SOI/EOI)
Safe increase of Turbo Boost Pressure (including twin-turbo)
Increase of Rail Pressure (Fuel Pressure) within engine protection limits
Improvement of Throttle Response
Expansion of torque limiter maps
Synchronization of PSA Group HDi twin-turbo engines
Multi-brand optimization (PSA, Ford, Jaguar-Land Rover)

Which Models Feature EDC17CP42?

This ECU is common in 2.2L diesel engines of various brands produced especially between 2006-2014. The most processed models in the OnlineChipTuning file panel are:

PSA Group (Peugeot-Citroen):

Citroen C5 2.2 HDi Twin-Turbo 204PS DW12C Diesel
Peugeot 508 2.2 HDi GT 204PS DW12CTED4 Diesel

Ford:

Ford Galaxy 2.2 TDCI 175-200PS Q4WA Diesel
Ford Mondeo 2.2 TDCI 175-200PS Q4BA Diesel
Ford S-Max 2.2 TDCI 175-200PS Q4WA Diesel

Jaguar-Land Rover:

Jaguar XF 2.2 TD 163-200PS Diesel
Land Rover Discovery 2.2 TD4 150PS Diesel
Land Rover Evoque 2.2 TD4/SD4 150-190PS Diesel

Why Customized Chip Tuning?

Factory software is left very conservative considering Euro 4/5 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", "SUV optimization for Evoque").

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 and engine torque.
Completely eliminates regeneration (DPF Regen) problems.
Provides turbo synchronization in PSA Group twin-turbo system engines.
Increases performance of Ford DuraTorq TDCI engines.
Optimizes features of Jaguar-Land Rover TD4/SD4 engines.
Makes adjustments while maintaining multi-brand characters (PSA sporty, Ford family, Land Rover off-road).

EDC17CP42 Stage 1 and Stage 2 Differences

Customized Stage 1

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 (+30-60 HP)
Turbo/Twin-Turbo System Optimization
Sharper Throttle Response
Emission Systems Active

Customized Stage 2

Specific to vehicles with modifications such as DPF Delete, EGR 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
Maximum Torque and Horsepower (+35-70 HP)
Multi-Brand Optimization

Special Solutions Offered with OnlineChipTuning

Since EDC17CP42 ECU is a diesel unit, we offer all emission system deletes and special performance solutions:

DPF / FAP OFF: Complete shutdown of the particulate filter system and elimination of continuous regeneration problems.
EGR OFF: Disabling the exhaust gas recirculation valve to keep the intake system clean.
VMAX OFF: Removal of factory speed limiter.

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 (DW12C, DW12CTED4, Q4WA, Q4BA, TD4, SD4), consider the vehicle type (sedan, MPV, SUV), add the features you want (e.g., Stage 2 + DPF Off + EGR Off + Twin-Turbo Sync) and send the file back to you.

Expert Advice: The EDC17CP42 is the ECU for 2.2L diesel engines used in a wide variety of brands but has some sensitive points. PSA Group's DW12C and DW12CTED4 twin-turbo engines are powerful (204 PS) but turbo synchronization is important. Faulty rail pressure and injection timing can cause injector and high-pressure pump damage. Ford 2.2 TDCI engines (Q4WA/Q4BA) are powerful engines with 175-200 PS; the EGR system is prone to carbon buildup. Jaguar XF 2.2 TD engine has a wide power band from 163-200 PS; correct version identification is important. Land Rover TD4/SD4 engines are optimized for off-road use; excessive torque increase can lead to differential and transmission stress. Due to Evoque and Freelander's compact SUV structure, thermal management is important. In automatic transmission models, excessive torque increase can lead to clutch problems. DPF regeneration causes problems especially in city use. In twin-turbo system models (PSA), both turbos must work balanced. OnlineChipTuning offers safe performance in every brand and engine type with EDC17CP42 experience.
