Heavy Equipment Parts stocks ECUs and electronic control units for excavators and heavy machinery. The ECU manages engine performance, hydraulic control, and machine diagnostics. A faulty ECU can trigger fault codes, reduce power, and in some cases prevent the machine from operating entirely. Our replacement ECUs are sourced from reputable suppliers and programmed to match OEM specifications for the relevant machine model. We service Komatsu, Caterpillar, Hitachi, Hyundai, Kobelco, and other major brands. Available from our Sydney warehouse with fast delivery across Australia.
