Mercedes PLD MR Software Modifications – Advanced Programming & Customisation for Mercedes Trucks
Mercedes PLD MR Software Modifications give operators full control over how their Mercedes-Benz MP1, MP2 and MP3 engines perform. At Autolectronix, we specialise in advanced software editing, recalibration and reconfiguration of PLD/MR modules used in Actros, Axor and Atego trucks, as well as Fuso trucks, Bell equipment and Marcopolo buses.
These engine control units determine injection timing, torque delivery, idle control, communication parameters and emissions behaviour. By applying professional Mercedes PLD MR software modifications, we can unlock new capabilities, adapt units for different applications, or resolve limitations caused by factory programming.
Whether you need horsepower adjustments, emission system changes, or full machine/bus conversions, our programming tools and technical expertise ensure safe, compatible and reliable results.
PLD MR Software Modifications Overview
Each module is connected to specialised programming and calibration equipment, allowing us to perform a wide range of controlled software operations, including:
AdBlue / DEF Removal
For off-road or export applications where AdBlue systems cause performance issues or are not required.
Horsepower (HP) Adjustments
Increase or decrease power output safely within the limits of your engine hardware and module version.
• Smaller engines: Moderate HP increases available
• V6 & V8 engines: Significantly broader adjustment range
To confirm available power levels, provide us with your module part number and engine type.
Engine Configuration Changes
Reflash the module to run on different engine families (e.g., 906 → V6/V8).
⚠ Note: 904 PLD modules are hardware-limited to 4-cylinder operation. Software can be changed, but the ECU cannot run more than four cylinders.
Truck → Machine Conversion
Convert truck-based PLD/MR software to run in earthmoving, agricultural or mining machines.
Machine / Bus Configuration
Recalibrate units for use in Marcopolo buses, Bell machines and other specialised applications.
Immobiliser Removal (Where Permitted)
Immobiliser deactivation may be possible depending on the vehicle.
• Mercedes MP1–MP3: Requires corresponding FR or CPC/FR programming
• Some ECU generations allow standalone immobiliser removal
Contact us for compatibility before sending your unit.
Typical Reasons for PLD MR Software Modifications
Operators request software changes for many reasons, including:
• Upgrading or downgrading horsepower
• Resolving compatibility issues after engine swaps
• Preparing a truck ECU for use in a machine
• Eliminating AdBlue-related failures
• Correcting injection coding mismatches
• Improving reliability on off-road equipment
• Adapting ECUs for fleet standardisation
Software modification is often far more cost-effective than replacement and offers customisation that OEM programming does not provide.
