Komatsu Plant Machinery ECU Tuning
Komatsu's SAA-series diesel engines — used across the PC, D, WA, and HM ranges — are well-engineered platforms that are conservatively calibrated from the factory. The same Komatsu machine sold in Japan, Europe, and developing markets must meet different emission standards with different fuel quality, so the factory map is built for the most restrictive common denominator.
A Komatsu-specific remap removes that restriction for UK site conditions — more low-end torque across the range, better fuel efficiency, and improved throttle response under load. We cover the full Komatsu plant range from PC01 mini excavators to D375/D475 large bulldozers, attending on-site with Komatsu-compatible ECU access equipment.
What's Included
- On-site service across the UK
- Komatsu-compatible diagnostic equipment
- Custom ECU calibration per machine
- Post-remap verification and data

Common Questions
Do you cover all Komatsu SAA-series engines?
Yes — SAA4D95, SAA6D95, SAA6D102, SAA6D107, SAA6D114, SAA6D125, SAA6D140, and SAA6D170 engines are all within our capability. These engines respond consistently to ECU remapping.
Can you remap a Komatsu D475 or other large dozer?
Yes — the Komatsu D275, D375, and D475 are within scope. These large production bulldozers use SAA6D140 and SAA6D170 engines that respond well to specialist calibration.
Do you fix Komatsu Adblue faults?
Yes. Komatsu Tier 4 and Stage V machines with Adblue (SCR) system faults can be addressed at the same site visit as the remap. Komatsu Adblue issues are among the most common plant downtime causes we see.
How do you access the ECU on a Komatsu machine?
We use Komatsu-compatible OBD and direct ECU access equipment. We arrive with the correct interfaces for the Komatsu range — no need to transport the machine to a workshop.
Do you offer fleet pricing for multiple Komatsu machines?
Yes. Fleet pricing applies for multiple machines from the same site visit. Tell us the models and site location when you enquire and we'll agree the price before attending.
