ECU Optimization on a Hyundai HL940XT Wheel Loader
This Hyundai HL940XT wheel loader arrived in the shop with the hood open, ready for a full diagnostic session and ECU readout. Machines like this spend their days pushing, lifting, loading, and running under constant hydraulic demand — so even small delays in throttle response or unnecessary fuel burn become noticeable over time.
After completing a detailed software scan and performance analysis, it was clear that the factory calibration left room for improvement in the low-RPM torque range, where loaders spend most of their operating time. The engine itself was in good mechanical condition, making it a perfect candidate for a software-only ECU recalibration.
Our optimization focused on improving usable torque, smoothing out power delivery, and reducing fuel consumption during repetitive loading cycles — all while keeping every safety and durability limit intact.
What the optimization achieved
- Stronger pushing power when entering piles
- Faster RPM recovery after reversing or lifting
- Smoother low- and mid-range power delivery
- Lower fuel consumption during high-frequency loading work
- More responsive operation with heavy buckets
The improvement was instantly noticeable during the test run. Instead of struggling to break into material, the loader moved with more authority — requiring less throttle and providing more usable torque.
