Cummins QSX (I) 450 14.95L 459hp (338kW) 2102Nm — industrial diesel engine of the commercial segment of the Cummins Inc. group (США, 1919). Stage 1 chip tuning raises power from 459 to 552 hp (+93 hp, +20%) and torque from 2102 to 2512 Nm (+410 Nm).
The Cummins B-Series is an iconic engine line (Dodge Ram, agricultural machinery). The Cummins ECU is a locked platform, tuned through specialised tooling. Cummins is the world leader in heavy-duty diesel-engine production volume. The top Cummins ISX marks the power ceiling for American trucks. The Cummins CM850/CM870/CM2350 ECUs are a proprietary platform. DPF/SCR with AdBlue is standard on modern Cummins engines.
Cummins confidently reaches Stage 2 with hardware (turbos, injectors). The Cummins ECU is a locked platform requiring specialised tooling. EFILive, MM3 and MiniMax are the main tools for Cummins (not the standard WinOLS). The top Cummins ISX engines mark the power ceiling of the American truck segment.
