Chip tuning for Cummins ISX 525 14.95L 527hp (388kW) 2244Nm ECU
Cummins ISX (I) 525 14.95L 527hp (388kW) 2244Nm — industrial diesel engine of the commercial segment of the Cummins Inc. group (США, 1919). Stage 1 chip tuning raises power from 527 to 615 hp (+88 hp, +17%) and torque from 2244 to 2490 Nm (+246 Nm).
The Cummins ISX is the flagship for Class 8 heavy trucks. Cummins is an American diesel-engine manufacturer, founded in 1919. The Cummins B-Series is an iconic engine line (Dodge Ram, agricultural machinery). 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.
