EMRT Professional SCR, DEF & DPF Emulator – Detroit Diesel GHG17
Direct ACM Replacement for New Gen Freightliner & Western Star (2017–2021)
 
The EMRT Professional Detroit Diesel GHG17 Emulator is our most advanced US-platform recovery module. Designed specifically for the high-data-rate environments of the GHG17 architecture, this module serves as a direct hardware replacement for the factory ACM (Aftertreatment Control Module). It provides a complete digital synthesis of the SCR, DEF (AdBlue), and DPF systems, restoring 100% engine torque and permanently resolving emissions-related downtime.
 
Key Features
Direct ACM Replacement: Save thousands on OEM hardware. This module completely replaces the factory ACM ECU. Simply disconnect the faulty original unit and plug the EMRT Emulator directly into the factory harness.
Full System Emulation: Digitally manages the entire GHG17 aftertreatment network, including sophisticated DEF quality monitoring, DPF soot-load logic, and high-frequency NOx correlation.
Plug & Play Integration: Engineered with factory-spec connectors for a secure, moisture-proof connection. No wire cutting or specialised tools are required.
Ruggedised for the Outback: Housed in a fully resin-sealed, waterproof casing. Built to endure the extreme vibrations and ambient heat typical of Australian B-Double and Road Train routes.
Connector Protection: Includes an original-spec protective cap for the factory ACM harness connector to prevent moisture and dust ingress.
 
Emulated Components
This module provides high-fidelity digital reporting for:
ACM ECU (Aftertreatment Control Module).
Upstream & Downstream NOx Sensors.
DEF Dosing Pump & Pressure Sensors.
DEF Level & Quality (Concentration) Sensors.
DPF Differential Pressure & Soot Load Signals.
Multi-point Exhaust Temperature Sensors.
 
Compatible Engines & Models
Optimised for Detroit Diesel GHG14 & GHG17 (2017–2021) Platforms:
Engines: DD5, DD8, DD13, DD15, and DD16 (GHG14/GHG17 variants).
Freightliner Models: Cascadia (Gen V), M2 106/112, 122SD, 114SD, EconicSD, and Business Class.
Western Star Models: 4700, 4800, 4900, and 5700 series (2017–2021 builds).
 
Installation Requirements
CRITICAL: Pre-Installation Service Routine To ensure the MCM (Motor Control Module) correctly syncs with the emulator, the following steps must be performed:
Reset: Perform the "DPF Ash Accumulator" service routine using diagnostic software (e.g., Detroit Diagnostic Link) before connecting the emulator.
Replace: Disconnect the factory ACM and install the EMRT Professional Emulator in its place.
Protect: Fit the included protective cap to the factory connector.
Exhaust: To prevent turbocharger damage, the physical DPF filter must be modified (drilled/hollowed) or replaced with a standard muffler.
