EAS3 Kenworth EAS3 Paccar MX EGR Removal Emulator
Plug-and-play EGR removal emulator for Kenworth trucks with Paccar MX-11 and MX-13 engines — permanently eliminates EGR valve clogging, pressure sensor faults and power derate on line-haul routes.
The Kenworth EAS3 EGR Removal Emulator is built for Kenworth line-haul trucks running Paccar MX-11 and MX-13 engines, where the EAS3-generation control unit continuously monitors the Exhaust Gas Recirculation system. On steady highway routes broken up by rest-stop idling, the EGR valve gradually cokes up with soot: valve position drifts, the differential pressure signal turns inconsistent, and the ECU pulls the truck into a protective derate that cuts speed and torque at the worst possible moment. Engineered by Hedef Emulator, this plug-in module continuously simulates EGR valve position, differential pressure and EGR cooler temperature signals so the EAS3 ECU reads the system as healthy at all times. No fault code is generated, no derate is triggered, and the engine keeps running at full rated output.
How Does It Work?
The emulator plugs directly into the truck's original EGR harness connector — no cutting or soldering — and can be removed at any time to restore the factory setup. Once installed, it continuously outputs EGR valve position, differential pressure feedback and EGR cooler temperature signals within the exact range the EAS3 ECU expects. The control unit reads the EGR system as fully functional, so no fault code is raised, no protective mode engages, and the engine runs at full power. No special software is required.
Frequently Asked Questions
Does this emulator work with both the Paccar MX-11 and MX-13 engine?
Yes, the emulator is designed for both Paccar engine families. We recommend confirming the vehicle-specific EAS3 ECU version against your VIN before ordering.
Will installation damage the original wiring harness?
No. The emulator connects to the existing EGR socket on a plug-and-play basis — no cutting or soldering — and can be unplugged at any time to restore the original setup.
Does this product also disable AdBlue, SCR or DPF?
No. This emulator covers the EGR system only; it does not affect AdBlue, SCR, DPF or NOx sensors in any way.
What are the shipping and warranty terms?
The product ships from stock with free worldwide shipping and is covered by a 2-year warranty.
