Excavator Tuning and ECU Software
On excavators the engine control unit (ECU) software is recalibrated on the machine's own original file. The original software is backed up; compatibility is confirmed by ECU type.
A power remap on the Excavator recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. On an excavator the engine drives the hydraulic pumps directly; with more torque in reserve, rpm drops less when digging, slewing and travelling at the same time. The calibration respects the limits of the engine and the hydraulic system.
Excavators spend long periods idling and under light load; in these conditions the particulate filter (DPF) cannot clean itself, asks for frequent regeneration and blocks. The EGR valve and cooler collect soot; with a NOx sensor, pump or injector fault in the AdBlue (SCR) system the machine enters limp mode and work on site stops. The cause is diagnosed first; the software solution is applied according to the ECU type.
Where is the difference noticed?
- Digging in hard ground and working with a breaker
- Digging, slewing and moving the boom at the same time
- Truck loading, where cycle time matters
- At high altitude and in hot weather
