Professional SCR, DEF & DPF Emulator
Direct ACM ECU Replacement for Volvo USA (US14 / US17 / US21)
The EMRT Professional VcomEM_VN_QC is a premium, heavy-duty recovery solution specifically engineered for US-spec Volvo trucks. Designed to meet the rigorous demands of US14 (GHG14), US17 (GHG17), and US21 (GHG21) standards, this module acts as a direct hardware replacement for the factory ACM (Aftertreatment Control Module).
By providing a total digital synthesis of the SCR, DEF (AdBlue®), and DPF systems, this emulator restores 100% engine torque and permanently resolves the terminal derates and "Check Engine" lights that plague these platforms.
Key Features
Direct ACM Replacement: Entirely replaces the factory Volvo ACM ECU. Avoid massive OEM hardware expenses by simply unplugging the faulty original and connecting the EMRT Emulator.
Full System Emulation: Digitally manages the entire architecture, including DEF pump pressure curves and complex NOx sensor correlation for D13TC engines.
Plug & Play Integration: Features factory-spec interfaces for a secure, moisture-proof connection. No wire cutting or dealer software required.
Industrial-Grade Build: Fully resin-sealed and waterproof. Built for the extreme vibration and thermal cycles of Australian long-haul routes.
Connector Protection: Includes an original-spec protective cap for the factory harness to prevent dust and moisture ingress.
Optimised for Volvo USA Platforms (2013–2025):
Standards: US14 (GHG14), US17 (GHG17), and US21 (GHG21).
Engines: 11L (D11), 13L (D13), 13L Turbo Compound (D13TC), and 16L (D16).
Volvo Models: VNL, VNR, VNX, VHD, and VAH series.
Installation & Requirements
Replace: Disconnect the factory ACM and install the EMRT Emulator.
Protect: Fit the included protective cap to the open factory connector.
Disconnect: Physically disconnect power from the original NOx sensors.
Physical Modification: The DPF filter must be modified (hollowed/drilled) to prevent backpressure. See our Physical Modification Guide.
Reset: Clear active codes using a diagnostic tool (or our VcomRT_US14 resetter) to restore full torque.
