The situation
The WA380 is a mid-size wheel loader that lives in loading cycles: into the pile, back, into the truck, back. The Cummins engine with the CM2350A ECU carries the full set of after-treatment – AdBlue/SCR, DPF and EGR – and on a loader that works short cycles at high load, that set generates more downtime than the rest of the machine put together.
The operator did not ask for more power. The brief was reliability and fuel: the after-treatment handled in software and the engine set up for lower consumption.
What we did
The CM2350A was read via OBD with Dimsport New Genius and the file developed for this software version – no bench work, no opening of the ECU.
- AdBlue/SCR: dosing and level monitoring deactivated in software, related DTCs and the derate strategy handled.
- DPF: regeneration logic disabled, back-pressure model and sensors neutralised.
- EGR: valve closed in software – clean intake, stable combustion temperatures.
- Eco: a light tune of injection and torque maps aimed at fuel economy in the loading cycle, not at peak power.
Checksum corrected and the file written via OBD.
The result
No regenerations, no AdBlue top-ups, no warnings and no derate, combined with lower fuel consumption per loading cycle. For the contractor this means a loader that stays in the pile instead of standing still for the after-treatment. Files for the CM2350A are developed from the original read of each machine – the software version decides what the file looks like.
