How it works

  1. Read your ECU

    With KESS, KTAG, AutoTuner or Flex. Keep the read: it is your way back.

  2. Match the numbers

    Your read must show hardware OM501LA.

  3. Pay and download

    Card, Apple Pay or Google Pay. The file is in your account straight away.

  4. Write it and drive

    Write it back the way you read it. Not right for your car? We correct it free.

What the car needs

Required modifications: Stage 1, Diesel.

Hardware

  • No hardware changes required: runs on completely stock hardware

Software / calibration

  • Boost pressure optimised within factory turbo limits
  • Injection timing & quantity remapped
  • Smoke / EGT limiters refined
  • DTCs left intact, factory safeties preserved

Stage 1 is a software-only calibration. Compatible with stock turbo, injectors, intercooler, exhaust and clutch.

Engine performance matrix

Power, torque and fuel-economy figures for every tuning stage on this engine, sourced from the tuning-database Gains API. Values are healthy-engine crank numbers; real on-road gains vary with fuel, altitude and mechanical condition.

About this calibration file

The Stage 1 calibration for the Mercedes-Benz Actros 1843 Turbo Diesel is a drop-in remap that works on completely stock hardware — no turbo, injector, intercooler or fuel-system upgrades required. Injection timing, boost targets, rail-pressure limits and torque maps are rebalanced to extract the safe headroom the OEM leaves untouched for fleet-fuel tolerance, altitude margin and warranty buffer.

This file matches a Temic ECU. Verify both identifiers in your flashing tool before writing — an ID mismatch is the most common cause of a bricked ECU. If you are unsure, upload a read of your original file via the file-request wizard and our engineers will confirm compatibility before you flash.

Projected output on a healthy, stock-hardware example of this engine: 528 HP and 1205 Nm at the crank — a gain of +100 HP (23%) and +206 Nm over the factory 428 HP / 999 Nm baseline. These numbers are sourced from our Vehicle Performance Database, which aggregates dyno results across this engine family. Real-world gains depend on fuel grade, ambient temperature, mechanical condition and intake/exhaust state.

The file is delivered as a ready-to-flash BIN (and ORI backup where applicable) compatible with all major tools — KESS V2/V3, KTAG, AutoTuner, CMDFlash, Dimsport New Genius, MPPS, Flex, BFlash, PCMFlash, MMFlash — via OBD, bench or boot-mode as supported by your ECU family. Checksums are pre-computed and verified; no additional checksum tool is required. All files include a free revision if post-flash logs reveal a fuelling, boost or EGT issue.

Frequently asked questions

The file is written for the exact ECU hardware (Temic) listed in the specifications. Read your ECU with any supported tool (KESS, KTAG, AutoTuner, CMD, etc.) and compare the hardware + software numbers against the ones on this page. If they match exactly, the file is a direct fit. If you're not 100% sure, upload your original read via the file-request wizard and our engineers will confirm within minutes — no cost, no obligation.

No. Stage 1 is explicitly a stock-hardware tune — no turbo, injector, fuel-pump, intercooler or exhaust changes are required. The only prerequisite is a mechanically healthy engine with good compression, clean EGR/DPF state, and fresh service fluids.

Re-flashing the ECU leaves a flag that a franchised Mercedes-Benz dealer can detect with their diagnostic tool. Most markets treat this as a basis to deny powertrain warranty claims that the modification could have caused. Emissions-sensitive components (DPF, EGR, SCR) remain fully functional with this calibration — we do not remove, disable or alter any emissions hardware.

The power and torque numbers on this page are healthy-engine crank figures. On a well-maintained Mercedes-Benz Actros 1843 running a known-good fuel brand, you should see a clearly perceptible increase in mid-range pull — typically from 1,800 to 4,000 rpm on diesel, 2,500 to 6,000 rpm on petrol — along with a shorter 80-to-120 km/h in-gear time. Thermal performance and fuel consumption depend on how you drive post-tune.

Instant. As soon as the payment clears, the file appears under Downloads in your account and the link is emailed to you. It does not expire: sign in and download it again whenever you need it.

Pre-corrected. Every tuning file we sell is processed through CHKSuite (our in-house checksum engine) before it reaches your download link. You can flash it directly with KESS, KTAG, AutoTuner, CMD, Dimsport or any other supported tool — no extra checksum step required. A zero-CRC write to a modern Bosch/Siemens/Delphi ECU bricks the unit, so this is non-negotiable.

Contact us on WhatsApp or through the dashboard support thread. Free revisions are included for the same stage on the same ECU — send us a live log (via VCDS, INPA, EcuConnect, OBDeleven or similar) and we'll adjust timing, boost, rail pressure or smoke limits and re-issue the file. A failed flash itself (write aborted, bricked ECU) is recoverable with our Original file and a bench tool.
