Every operation below can be ordered for the same DCM1.2 DDCR file (diesel). Prices are per file in EUR; automatic solutions are delivered within minutes, engineer-assisted ones are prepared by our tuning team.

STAGE1 A safe performance tune that needs no mechanical changes and does not harm the vehicle. automatic, 2 ready solutions for this file size · ~15 min 10 EUR
STAGE2 A performance tune that requires hardware changes such as exhaust, filter or DPF removal. engineer-assisted, on request · ~60 min 40 EUR
DPF OFF Deletes the diesel particulate filter (DPF) system in software; if the vehicle has AdBlue, it must be deleted first. engineer-assisted, on request · ~5 min 5 EUR
EGR OFF Disables the exhaust gas recirculation (EGR) system. done in this project ✓
LAMBDA OFF Disables the oxygen (lambda) sensors. engineer-assisted, on request · ~5 min 5 EUR
DECAT Disables catalytic converter efficiency monitoring and the P0420/P0430 fault codes. engineer-assisted, on request · ~5 min 5 EUR
VMAX OFF Removes the speed limiter (Vmax) or sets it to the desired value. engineer-assisted, on request · ~5 min 5 EUR
TVA OFF Disables the diesel throttle valve. engineer-assisted, on request · ~5 min 5 EUR
FLAPS OFF Disables the swirl flaps in the intake manifold. engineer-assisted, on request · ~5 min 5 EUR
IMMO OFF engineer-assisted, on request · ~180 min 50 EUR
HOT START Fixes the rough/delayed starting issue (hot start) that occurs when the engine is hot. engineer-assisted, on request · ~10 min 20 EUR
REVLIMIT Adjusts the engine rev limiter (hard cut) point. engineer-assisted, on request · ~20 min 10 EUR
DTC OFF Permanently disables the fault codes (DTC) you select; you need to provide the P codes to turn off. automatic, instant 10 EUR
CHECKSUM OK Automatically calculates and corrects your modified file’s checksum; if your tool cannot do checksums, we do it for you. automatic, instant 1 EUR
REV ORI engineer-assisted, on request · ~120 min 10 EUR

About this project

Delphi DCM is a diesel common-rail ECU family used by Ford, PSA, Renault, VAG, Kia and others. This unit is fitted to PEUGEOT - CITROEN Car vehicles. Project #1892 was completed automatically by the ECUHARD file service for a PEUGEOT - CITROEN Car vehicle running software 9645361680 9650043480.

Frequently asked questions

What was done to this DCM1.2 DDCR file?

Operations performed: EGR OFF. The modified file was checksum-corrected and delivered ready to flash.

What is the software version for this DCM1.2 DDCR file?

This project is for DCM1.2 DDCR with software numbers: 9645361680, 9650043480. The same operations apply to other vehicles running the same software.

Can I get the same tuning for my PEUGEOT - CITROEN?

Yes. Sign in, upload your original ECU file (DCM1.2 DDCR or any supported ECU), choose the operations you need and our automated system prepares the file, usually within minutes, 24/7.

I read my ECU with a different tool — will the tuning fit my file?

Yes. Every operation is applied to the file you upload — your own read from your own car — so the tool and the read mode do not matter: the modifications are located by content, not by a fixed file layout. If your file was modified before, our REV ORI (revert to original) module repairs every changed area back to the stock values first — no matter which tool or method read it (KTAG, KESS, Flex, Autotuner, CMD, OBD, bench or boot) (10 EUR). A compatibility problem is therefore impossible.

I have an OBD read — can you tune it, or do I need a bench/boot read?

An OBD read is fine as long as it contains the software area (maps). Upload it; the platform detects the ECU and software number and shows which operations are available for your file. If the read is partial and an operation is not possible on it, you will see that before paying.

I read boot mode with KTAG / bench with Flex / bench or OBD with Autotuner — which read do I upload?

Any of them. Upload the file exactly as your tool saved it (DCM1.2 DDCR reads are supported in OBD, bench and boot form). The system works on your own read, so nothing has to be converted or matched to a different device.

Do you need the full backup (EEPROM, other sectors)?

No. Only the software-related part of the ECU is used: the maps area — the internal flash and/or the external flash, depending on where the software lives in that ECU. EEPROM and other memory sectors are not needed and are never modified. Keep your full backup for yourself as a safety copy.

How can I be sure the result will be compatible with my ECU?

Because the file returned to you is your own read with only the selected areas changed and the checksum corrected, it flashes back with the same tool and method you used to read it. The software number stays the same; nothing else in the file is touched.

What other operations are available for DCM1.2 DDCR?

STAGE1 (10 EUR, automatic, 2 ready solutions for this file size); STAGE2 (40 EUR, engineer-assisted, on request); DPF OFF (5 EUR, engineer-assisted, on request); LAMBDA OFF (5 EUR, engineer-assisted, on request); DECAT (5 EUR, engineer-assisted, on request); VMAX OFF (5 EUR, engineer-assisted, on request); TVA OFF (5 EUR, engineer-assisted, on request); FLAPS OFF (5 EUR, engineer-assisted, on request); IMMO OFF (50 EUR, engineer-assisted, on request); HOT START (20 EUR, engineer-assisted, on request); REVLIMIT (10 EUR, engineer-assisted, on request); DTC OFF (10 EUR, automatic, instant); CHECKSUM OK (1 EUR, automatic, instant); REV ORI (10 EUR, engineer-assisted, on request). Prices are per file.

I have a DCM1.2 DDCR file — how can I get it done?

Sign in to the ECUHARD platform (solutions.ecuhard.com), upload your ECU file, select the operations you need and confirm. Automatic solutions are delivered within minutes, 24/7; engineer-assisted operations are prepared by our tuning team. Each file is checksum-corrected and an invoice is issued automatically.

Do I need to send my original file?

Yes — upload the stock read of your ECU. If you do not have it, our original file archive may have a matching file by software number.
