EMRT Professional SCR / DOC Emulator – Liebherr Tier 4 Final
Plug & Play Solution for D9xx A7 04 Engines (ECU2 Controller)
 
The EMRT Professional SCR / DOC Emulator is a high-performance, dedicated solution for Liebherr excavators and material handlers. Specifically designed for machines equipped with the ECU2 engine controller, this unit provides a complete bypass of the SCR and DOC systems, ensuring your machine stays out of "Limp Mode" and remains productive on the job site.
 
Key Features
Full SCR & DOC Emulation – Replaces all signals for the AdBlue dosing and oxidation catalyst systems, preventing fault codes and performance loss.
Automatic Derate Cancellation – Unlike other solutions, engine torque reduction is disabled automatically. No diagnostic tool or software reset is required.
ECU2 System Test Support – Fully supports the specialised internal SCR system tests performed by the Liebherr ECU2 controller for seamless integration.
Ruggedised Industrial Housing – 100% waterproof and manufactured with automotive-grade components to survive the extreme vibrations of heavy excavation.
Rapid Deployment – Just install the device and warm up the engine; all SCR/DOC faults will become inactive immediately.
