The Cummins Celect Electronic Control Module (ECM) is the trusted power management system for N14 diesel engines, delivering fuel efficiency, advanced diagnostics, and reliable performance for Class 8 trucks. Built for durability and easy serviceability, the Celect ECM features precise fuel management, onboard monitoring, and compatibility with Celect and Celect Plus engines. Whether in long-haul, vocational, or fleet applications, it keeps trucks running efficiently while reducing downtime and operating costs. Every Weller Celect and Celect Plus ECM is disassembled and rebuilt with over 65 new and upgraded parts. High current and high duty cycle components are replaced by IPC certified technicians regardless of core condition, and a new polymer case is installed providing better corrosion resistance and a lower internal ECM temperature. Weller’s remanufacturing process exemplifies a commitment to quality, reliability, and innovation. Weller's remanufactured Celect and Celect Plus ECMs face rigorous multi-stage testing to guarantee every unit is ready for demanding applications, providing customers with dependable, high-performance solutions they can trust.
