Every operation below can be ordered for the same MCM2 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, 1 ready solution in library · ~30 min 100 EUR
ADBLUE OFF Disables the AdBlue (SCR) system in software; no AdBlue refills are needed afterwards. done in this project ✓
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 · ~15 min 100 EUR
EGR OFF Disables the exhaust gas recirculation (EGR) system. automatic, 1 ready solution in library · ~15 min 50 EUR
LAMBDA OFF Disables the oxygen (lambda) sensors. engineer-assisted, on request · ~10 min 50 EUR
NOX OFF Disables the NOx sensor. done in this project ✓
VMAX OFF Removes the speed limiter (Vmax) or sets it to the desired value. engineer-assisted, on request · ~20 min 50 EUR
TVA OFF Disables the diesel throttle valve. engineer-assisted, on request · ~20 min 100 EUR
FLAPS OFF Disables the swirl flaps in the intake manifold. engineer-assisted, on request · ~20 min 100 EUR

About this project

MCM2 is an engine control unit (ECU) supported by our automated file service. This unit is fitted to MERCEDES TRUCK Truck vehicles. Project #23216 was completed automatically by the ECUHARD file service for a MERCEDES TRUCK Truck vehicle running software R_912043_1GF508S067 P09.12.00.043 0004466935003.

Frequently asked questions

What was done to this MCM2 file?

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

What is the software version for this MCM2 file?

This project is for MCM2 with software numbers: R_912043_1GF508S067, P09.12.00.043, 0004466935003. The same operations apply to other vehicles running the same software.

Can I get the same tuning for my MERCEDES TRUCK?

Yes. Sign in, upload your original ECU file (MCM2 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) (75 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 (MCM2 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 MCM2?

STAGE1 (100 EUR, automatic, 1 ready solution in library); DPF OFF (100 EUR, engineer-assisted, on request); EGR OFF (50 EUR, automatic, 1 ready solution in library); LAMBDA OFF (50 EUR, engineer-assisted, on request); VMAX OFF (50 EUR, engineer-assisted, on request); TVA OFF (100 EUR, engineer-assisted, on request); FLAPS OFF (100 EUR, engineer-assisted, on request); IMMO OFF (200 EUR, engineer-assisted, on request); REVLIMIT (50 EUR, engineer-assisted, on request); DTC OFF (50 EUR, automatic, instant); REV ORI (75 EUR, automatic, stock file in archive). Prices are per file.

I have a MCM2 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.

Is there an ECM Titanium driver for this MCM2 file?

Yes. The file is linked to ECM Titanium driver ACT_5E53 (MERCEDES TRUCK ACTROS 1845). Matched: the software range is identical to the driver reference. The driver tells the software where the maps of this ECU software are, so tools that use ECM drivers, including the ECUHARD Tuning Editor, can open the maps 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.
