EMRT SCR Emulator for Hitachi-Isuzu (Tier 4 Final & Stage V*)
The EMRT Plug & Play solution offers a simplified, non-intrusive method for the permanent deactivation of the Selective Catalytic Reduction (SCR) system on Isuzu Tier 4 Final (T4F) and Stage V* engines. Engineered for the rigours of Australian conditions, this unit prevents engine derating and fault codes without the need for complex ECM remapping.
Key Features
Complete SCR Emulation: Achieves full, continuous electronic simulation of all critical SCR system components to keep your machine running at 100% power.
EMRT Plug & Play Interface: A high-efficiency design that requires the connection of only one power wire (Pin252 DCU_2 Plug), making installation fast and straightforward.
Industrial-Grade Build: Housed in a fully water-resistant and sealed enclosure, using durable electronic components designed for maximum resilience in harsh operating environments.
No Programming Required: Works directly with the factory Engine Control Module (ECM) to provide correct simulated signals, avoiding the need for expensive software tunes.
Eliminate Derates: Stops the frustrating engine "Limp Mode" events caused by Urea quality issues or pump failures.
Emulated Components
The EMRT module outputs precise simulated signals to the Engine ECM for the following sensors and actuators:
Upstream and Downstream NOx Sensors
Urea Quality and Level Sensor
DCU (Dosing Control Unit)
Urea Pump
Simple Installation Guide
Wire Integration: Connect the four designated harness wires to the factory system as per the included EMRT wiring schematic.
System Sync: The emulator will automatically begin outputting the correct data to the ECM upon start-up.
Physical Bypass: For the best results and to prevent back-pressure, it is recommended to ensure the exhaust flow is unobstructed.

*Important Note on Stage V Models
This EMRT module is designed primarily for engines featuring an SCR catalyst only.
Stage V Support: While usable on Isuzu Stage V engines equipped with both SCR and DPF systems, DPF (Diesel Particulate Filter) emulation is not supported in this release. * Development: Full, integrated support for Stage V SCR and DPF is currently under development.
Why Choose EMRT?
In the Australian construction and mining industries, downtime is the enemy.
Permanent Fix: Tired of replacing $3,000 NOx sensors? The EMRT solution is a one-time investment that ends AdBlue-related headaches for good.
Local Support: Designed to handle the heat and dust of local worksites, ensuring your Hitachi or Isuzu gear stays in the dirt and out of the workshop.
