SCR DPF EGR Off for CHENGLONG

Optimize Heavy-Duty Power with File Services for Chenglong

We specialize in providing File Services for Chenglong trucks and tractor heads, focusing on enhancing engine performance and eliminating limitations from emission control systems like EGR, DPF, and SCR (AdBlue/DEF). These systems can often cause reduced power, increased fuel consumption, and recurring error codes. Our services cover robust models such as the LIU QI YC4S130, LIU QI YC6JA240-50, the high-powered LIU QI YC6K13.52-50, and the M7 TRACTOR HEAD, all equipped with reliable Bosch EDC17CV44 ECUs. By calibrating the ECU and removing unnecessary software restrictions, we unlock the full power potential of the engine, reduce operating costs, and improve reliability in demanding usage. Trust our Calibration Files for Chenglong to bring maximum efficiency and durability to your fleet.
