Online remapping service
Our most popular service is our online remapping service. This means you can benefit from one of our high quality custom written remaps from anywhere in the world. All you need is to find the correct hardware to connect to the ECU of your vehicle.
When using the HDI Tuning online remap service you get a much more complete service than any other company is able to offer, thanks to our 10 Years of experience in writing software for just the Peugeot and Citroen HDI engines, we know these engines and the software like nobody else. We offer full support with diagnostics and fault finding, and also we can analyse performance data before and after your remap to check everything is running as it should.
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.
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 firstname.lastname@example.org 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 the high quality remap file has been made, 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.
What 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.
Payment: Payment can be made here.
All of our guides and instructions are available on our downloads page.
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. For this you will need a BDM100 programming tool.
The reason we advise to use a BDM100 tool is because it creates 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.
We've produced an in depth video guide to using the BDM100 tool, and instructions are also available.
Once you have a read and backup of your ECU, send it all over and we'll make your remap. Payment can be made online through PayPal.
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, and you need to send an encrypted pulse to the boot strap loader pin of the processor. Luckily most modern equipment can do this, 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.
We use the MPPS tri-core add on module which also comes with a breakout box which handles the OBD to ECU plug wiring.
These ECUs are really hard to open, and there's a high risk of damage, so we advise that you send it to us, unless you are experienced with electronics/ECUs.
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. This option is the better choice, as you then get a full backup of the EEPROM and the full flash. If you read/write over OBD there is a high risk of crashing the ECU, and you will only get half of the flash data. This ECU must be opened, and the boot pin must be soldered, so we recommend that you send this to us if you are unfamiliar with ECU tuning.
