Backhoe Loader Tuning and ECU Software
On backhoe loaders 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 Backhoe Loader recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. On a backhoe loader one engine feeds the front bucket, the rear excavator and the drivetrain; with more torque in reserve, rpm drops less when digging and roading.
Backhoe loaders often sit idling between short jobs during the day; in these conditions the particulate filter (DPF) cannot clean itself and blocks. The EGR valve collects soot; with a NOx sensor or pump fault in the AdBlue (SCR) system the machine enters limp mode. The cause is diagnosed first; the software solution is applied according to the ECU type.
Where is the difference noticed?
- Working in hard ground with the rear excavator
- Loading and grading with the front bucket
- Roading between sites and on hills
- Working with hydraulic attachments such as breakers
