Delphi – engine control units and Common Rail injection systems

Delphi is one of the best-known manufacturers of automotive electronics and Common Rail injection systems used in modern petrol and diesel engines. Delphi solutions can be found in millions of passenger cars, vans and commercial vehicles all over the world.

Delphi products are widely used by manufacturers such as Ford, Renault, Nissan, Hyundai, Kia, SsangYong, Peugeot, Citroën, Opel and many other vehicle makers. The company specialises in engine control units, injection systems, electronic modules and engine management solutions, among others.

Delphi engine control units

Delphi engine ECUs control engine operation, the fuel system, the turbocharger and emissions, and communicate with the other modules of the vehicle. Popular Delphi ECU families found in many cars include DCM3.4, DCM3.5, DCM6.2, DCM7.1, DDCR and MT.

A properly working engine ECU is essential for vehicle performance, fuel economy and the reliable operation of all electronic systems. At ECUSALE we offer ECUs prepared as VIRGIN, IMMO OFF, CLONE or Plug & Play, depending on the specific part number and the technical possibilities of the module.

Delphi DCM3.5 – popular engine ECUs for Ford 2.0 TDCi

One of the most common Delphi engine ECUs is the DCM3.5, widely used in Ford cars with 2.0 TDCi engines. ECUs from this family can be found in the Ford Mondeo, Focus, Kuga, C-Max, S-Max, Galaxy and Transit, among others.

Delphi DCM3.5 modules control the Common Rail injection system, the turbocharger, fuel pressure and emission systems, and communicate with the immobiliser and the other control units of the vehicle.

You will find DCM3.5 units for different vehicle and engine versions in the Ford engine ECUs category.

Frequently chosen Delphi DCM3.5 ECUs include:

• BG91-12A650-FFE 28403820 – Ford Delphi DCM3.5 engine ECU.
• BG91-12A650-FHF 28425303 – Ford Delphi DCM3.5 engine ECU.

Depending on the ECU version and how it has been prepared, fitting may require transferring data from the original module, programming the VIN or adapting the PATS immobiliser.

Delphi Common Rail injection systems

Delphi is one of the pioneers of the Common Rail technology used in modern diesel engines. Its electronics work with high-pressure pumps, injectors and the sensors responsible for precise fuel metering.

Thanks to advanced technology, Delphi systems provide smooth engine operation, optimal fuel consumption and the ability to meet strict emission standards.

Which vehicles use Delphi products?

Delphi engine ECUs and electronics are very popular in Ford cars. They can be found in the Ford Focus, Ford Mondeo, Ford Kuga, Ford C-Max, Ford S-Max, Ford Galaxy and Ford Transit, among others.

Delphi products are also used in the Renault Master, Renault Trafic, Renault Megane, Renault Scenic, Nissan Qashqai, Nissan Primastar, Opel Vivaro, Hyundai Tucson, Kia Sportage, Peugeot Boxer, Citroën Jumper and many other models with Delphi Common Rail systems.

Why choose Delphi products?

• Advanced Common Rail injection systems.
• Wide use in passenger cars and vans.
• Popular DCM, DDCR and MT ECUs.
• Good availability of parts and programming options.
• Solutions used by many vehicle manufacturers.
• VIRGIN, IMMO OFF, CLONE and Plug & Play ECUs available.

How to choose the right Delphi ECU?

When choosing a Delphi ECU, the most important thing is to compare all part numbers on the label of the original module. The same vehicle model often comes with different ECU versions, so choosing only by model, engine size and year is not always enough.

Compare the Delphi part number, the vehicle manufacturer’s OEM number and the hardware and software identifiers of the ECU. If you are not sure which module is right, send us a photo of the label or the vehicle’s VIN. We will help you check the compatibility of the chosen product.

Frequently asked questions about Delphi

What are Delphi DCM ECUs?

Delphi DCM ECUs are used mainly in modern Common Rail diesel engines. They control fuel injection, the turbocharger and emissions, and communicate with the other systems of the vehicle.

Which cars use the Delphi DCM3.5 ECU?

Delphi DCM3.5 ECUs are often used in Ford cars with 2.0 TDCi engines, including the Mondeo, Focus, Kuga, C-Max, S-Max, Galaxy and Transit. Always compare the full numbers on the ECU label before buying.

Which cars use Delphi ECUs?

Delphi ECUs can be found in Ford, Renault, Nissan, Opel, Hyundai, Kia, Peugeot, Citroën and many other makes that use Delphi Common Rail systems.

Do Delphi ECUs need programming?

That depends on the specific part number and how the ECU has been prepared. We offer ECUs as VIRGIN, IMMO OFF, CLONE and Plug & Play. Information on fitting, VIN programming and immobiliser adaptation is always given in the product description.

Do Delphi DCM3.5 ECUs need immobiliser adaptation?

Depending on how the Delphi DCM3.5 ECU has been prepared, it may be necessary to transfer data from the original module or to adapt the PATS immobiliser with a suitable diagnostic tool. The exact procedure depends on the vehicle model and the ECU version.

Can Delphi ECUs be cloned?

Yes. Many Delphi ECUs allow the data from the original module to be cloned. This makes it possible to transfer the vehicle configuration, the VIN and the immobiliser data to the second ECU.

Are Delphi products tested before dispatch?

Yes. Delphi engine ECUs and other electronic modules are checked before dispatch for communication and basic functionality.

How do I choose a Delphi ECU for a Ford or a Renault?

The most important thing is to compare all the numbers on the original ECU. If in doubt, send us a photo of the label or the vehicle’s VIN so that we can check compatibility.

Safety information

Delphi automotive electronics should be fitted by people with the right technical knowledge and access to vehicle diagnostics. Always check the part number and compatibility with the vehicle before buying. Incorrect fitting, programming or adaptation may cause faults in the vehicle and its electronic systems.
