How to re-program your ECU from home

To use the online remap service you need to get a read of your ECU, and then send the data over to us via email.

Send the standard ECU data file to remap@hdi-tuning.co.uk and we will make you a custom remap from your original ECU software. Make sure you send payment over at the same time, we won’t send the remap back until this has been received.

When your remapped software has been prepared it will be emailed back to you and you can then upload it using the same tool which you used to read the data. The typical turn around time is less than 24 hours for this file only service. On some occasions we may take slightly longer if we are at a very busy period.

It’s important that your vehicle is running in tip top condition before you go ahead with a remap, a remap can only improve power if all components are functioning as they should. Of course we can remove faults created by components such as a blocked DPF, broken EGR, or faulty intake throttle flaps and many more.

Which tool do I need to read/write my ECU?

There are a few different types of ECUs fitted to the HDI engines, we’ll help you find which model you have based on the engine and the power level. To be certain, take a look at the vehicle specific page for your car, or check under the bonnet and find the ECU. The links to buy these tools are from sellers outside of our company, we do not stock these tools these are simply affiliate links to eBay to save you the time of finding them, you’ll still get the best price and you’ll be sure to get the right tool. Please make us aware of any outdated or broken links.

Bosch EDC15C2 injection system

We can offer a complete online remapping service for any vehicle fitted with the 2.0 or 2.2 HDI engine if it is fitted with the Bosch EDC15C2 control system. – For this you need an MPPS tool.

The process is simple, first you connect to your vehicle through the diagnostic port, you then send us the original ECU data along with payment for the service you require. Once we have received this from you, we then proceed to make you a custom remap and we will email it back to you as soon as it is ready.

Using the same equipment you can then program your vehicles ECU and your vehicle is then remapped.

You can check here to see if the service is available for your vehicle.

Bosch EDC16 injection system

We can also offer an online remapping service for the 1.4 and 1.6 HDI engines produced until the end of 2009. These engines are paired with a Bosch EDC16 ECU. There are two methods to program these ECUS:

• Bench programming can be carried out using BDM100 or Kess KTAG direct to the BDM port. BDM programming can create a backup of not only the flash memory (maps and engine software), but also a backup of the immobiliser, the ECU configuration, and the injector codes.
• An easier method of programming is using Kess V2 over the OBD port in the vehicle. As long as the vehicles battery and the laptop are connected to chargers and the process is not interrupted, this can be a reliable process. For Ford EDC16 from 2008 to 2010 it is not possible to program over OBD.

We’ve produced an in depth video guide to using the BDM100 tool, and instructions are also available.

Bosch EDC17C10 Injection system

The later 1.6 HDI engines use a much more complex ECU system with the infineon tricore ‘tuning protected’ processor. This basically means that you can’t program through the OBD port, unless you have the most up to date equipment such as AutoTuner.

Most equipment can program this ECU in bench mode so it’s just a case of opening up the ECU, and then attaching the boot pin and the other wires to the main ECU connector.

• Program with an open ECU using Kess KTAG.
• These ECUs are really hard to open, and there’s a high risk of damage, so a much safer method is to program using a tool which has a bench loader and this does not require the ECU to be opened. PCM Flash or KTM bench (cheaper alternative) can program on the bench by connecting only 7 wires it’s very simple and very safe to do.

Delphi DCM 3.4

The DCM 3.4 can be programmed through the diagnostics port with most authentic equipment. The Kess V2 is a good tool to do use for this ECU model.

Delphi DCM 3.5

The DCM 3.5 can be programmed through the diagnostics port with most authentic equipment, and it can also be read on the bench in boot mode.

• Program over OBD port using Kess V2 – this is the easiest method and does not require disassembly of the ECU.
• Open the ECU and program in bench mode using Kess KTAG. This option gives a full backup of the EEPROM and the full flash.
