EMRT Professional SCR / DOC Emulator – Perkins 1204F-E44TA
Tier 4 Final / Stage IV "Quick Connect" Solution
 
The EMRT Professional Perkins 1204F Emulator is a high-performance, dedicated Plug & Play solution designed for engines equipped with the Tier 4 Final aftertreatment system. This unit provides a complete bypass of the SCR and DOC systems, automatically disabling engine torque reduction (limp mode) without the need for expensive diagnostic software.
 
Key Features
Full SCR & DOC Emulation – Replaces all signals for the AdBlue dosing and oxidation catalyst systems, preventing performance loss and idle-speed derates.
Plug & Play QC Integration – Features a specialized "Quick Connect" (QC) harness for immediate installation. No wire cutting or soldering is required.
Automatic Derate Cancellation – Fully supports the internal SCR system tests managed by the Engine ECM. Torque reduction is automatically disabled upon installation.
Ruggedised Protection – Housed in a 100% waterproof industrial casing, built to withstand the extreme vibration and heat of construction sites.
DCU Module Bypass – Includes a professional-grade blanking plug for the original PETU/DCU module connector to ensure a clean, moisture-proof installation.
