Navara NP300 — Stage 2 ECU Tune
- Recovery from limp mode operation
- Optimized combustion temperature management
- Maintained power output under heavy towing load
- Enhanced reliability for sustained trailer towing
- Resolution of ECU defect
This 2018 Navara NP300 came in with a replacement ECU already fitted, and the owner wanted a calibration to match. The dyno result recorded 28 kW at the wheels before the tune and 121 kW afterward—a 93 kW gain—with torque landing at 427 Nm.
Stage 2 here means software and basic supporting work beyond a flash-only tune. The file was developed to suit the replacement ECU platform and the hardware already on the truck. It's the kind of job where you're working with what's been done and making sure the calibration pulls it all together cleanly.
Suited to off-road and closed-circuit use, given the output level.
What ECU platform was this tuned on?
The ECU platform used wasn't recorded in this build sheet. The file was developed for the replacement ECU fitted to this particular truck.
Is this a flash tune or a full standalone install?
This is a Stage 2 build with a replacement ECU already installed. The tune is a custom calibration for that ECU, not a reflash of the factory unit.
What was the baseline power before tuning?
The dyno recorded 28 kW at the wheels before calibration, then 121 kW afterward—a gain of 93 kW.
