Komatsu WA380 Wheel Loader Tuning and Power Upgrade
The Komatsu WA380 is Komatsu's wheel loader. The engine control unit (ECU) software is recalibrated on the machine's own original file; the original software is backed up.
Komatsu WA380 technical data
Each row states where the data comes from. “Manufacturer data” is the factory figure published by the manufacturer; figures after a remap are shown only where we have our own measurements and records. Estimated figures are not guaranteed results.
| Engine | Power | Torque | ECU | Read / write | Verification |

Komatsu WA380 power remap
A power remap on the Komatsu WA380 recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. On a loader the engine feeds both the drivetrain and the bucket hydraulics; with more torque in reserve, rpm drops less when entering the pile and climbing ramps with a full bucket.
Komatsu WA380 DPF, EGR and AdBlue fault solution
Loaders shuttle back and forth over short distances; the particulate filter (DPF) often fails to reach regeneration temperature and blocks. With an EGR fault or a NOx sensor fault in the AdBlue (SCR) system the machine enters limp mode and loading stops at the quarry or plant. The cause is diagnosed first; the software solution is applied according to the ECU type.
ECU and compatibility for the Komatsu WA380
Services with a verified solution for Komatsu in our library: Stage 1 Remap, DPF Delete, EGR Delete and AdBlue / SCR Delete. The same model can carry a different ECU depending on build year and engine option, so we confirm compatibility for the Komatsu WA380 from a photo of the ECU label or from the file read out.
Where is the difference noticed on the Komatsu WA380?
- Entering the pile and filling the bucket
- Climbing ramps and slopes with a full bucket
- Truck loading, where cycle time matters
