EMRT Professional SCR, DEF & DPF Emulator – Paccar MX GHG17
Full Aftertreatment Bypass for Kenworth & Peterbilt (2018–2022)
 
The EMRT Professional Paccar MX GHG17 Emulator is a premium, all-in-one recovery kit designed for the advanced EAS-4 aftertreatment architecture. Engineered for US-spec MX-11 and MX-13 engines, this solution includes a sealed downstream NOx dummy sensor plug, allowing for a complete digital and physical bypass of the emissions system. Restore 100% engine torque and permanently eliminate AdBlue (DEF) consumption, DPF regenerations, and performance-limiting derates.
 
Key Features
Advanced EAS-4 Emulation: Specifically programmed to handle the high-data-rate communication and "Stage E" logic found in 2018–2022 Paccar GHG17 platforms.
Sealed NOx Dummy Plug Included: Features a custom-engineered downstream NOx sensor emulator that clicks directly into the factory harness. This replaces the physical sensor entirely, preventing future hardware failures.
100% Plug & Play: No wire cutting, splicing, or specialised dealer software required. The module establishes a secure handshake with the Engine Management System to keep the dashboard clear of CEL and "Red Dash" warnings.
Limp Mode Recovery: Instantly clears "AdBlue System Fault" and "Soot Level High" warnings, preventing the terminal 5 km/h "crawl mode."
Ruggedised for the Outback: Housed in a fully resin-sealed, waterproof casing designed to survive extreme heat and high-vibration environments.
 
Emulated Components
This module provides high-fidelity digital reporting for:

Downstream NOx Sensor (Via included sealed dummy plug).
PM (Particulate Matter) & DPF Differential Pressure Sensors.
DEF Level & Quality (Concentration) Sensors.
Combined Exhaust Temperature Array.
 
Compatible Engines & Models
Optimised for Paccar MX GHG17 (2018–2022) Platforms:
Engines: Paccar MX-11 and MX-13 (GHG17 Variants).
Kenworth Models: T680, T880, and W990.
Peterbilt Models: 579, 567, and 389.
 
Installation Overview (Approx. 15 Minutes)
NOx Replacement: Remove the original downstream NOx sensor and install the included EMRT Sealed Dummy Plug into the factory harness.
Power Down: Locate and pull the ACM/EAS Power fuses to allow the emulator to take full control of the CAN-bus.
Exhaust Flow: The physical DPF filter must be modified (drilled/hollowed) or replaced with a standard muffler to prevent exhaust backpressure.
