About remapping

The Mercedes-Benz Actros is the brand's heavy truck and accounts for 438 files in our catalogue, with designations such as 1841, 1844 and 2541 and displacements around 12 and 12.8 litres. It is a long-haul tractor unit where fuel consumption governs profitability.

Stage 1 makes up 369 files, with 67 AdBlue-related files and 18 EGR off. The ECUs are Mercedes' own: ZGS001, ZGS002 and ZGS003, alongside the ACM and MCM2.1 units and the HDEP references. In commercial vehicles we work to more conservative criteria than on cars.

Remapping services

Stage 1

Optimising the original map with no hardware changes: more power and torque, full reliability.

AdBlue/SCR off

AdBlue/SCR system management to avoid faults and lock-outs.

EGR off

EGR valve management to reduce soot issues and improve response.

Stage 2

Remap for vehicles with mechanical upgrades (intake, exhaust, intercooler…).

DPF off

Particulate filter solution: no more regenerations or blockage warnings.

Stage 3

Setup for high-performance modifications on specific hardware.

DTC delete

Clearing of fault codes (DTC) that can't be removed via diagnosis.

Frequently asked questions

What does a long-haul truck gain?

Fuller torque at low revs and, in many fleets, a more contained average fuel consumption. Over high annual mileage, small efficiency gains matter considerably.

Does it affect engine life?

On commercial vehicles we work to more conservative criteria precisely because the engine accumulates far more hours than a car engine.

Can I modify the AdBlue system?

Tampering with emissions systems is restricted on vehicles used on public roads. Ask us about your specific case before ordering anything.
