Patrol — Stage 1 ECU Tune
- Improved power delivery
- Improved torque characteristics
- Smooth power band
- Enhanced drivability
- Daily commute capability
This 2000 Patrol runs an L98 6.0L V8 and 6L80 transmission swap, retaining the factory ECU. The owner wanted a reliable touring setup that could handle long highway runs and loaded trips without needing standalone engine management.
We calibrated the factory ECU to match the high-pressure fuel pump and upgraded injectors, targeting driveability and fuel economy rather than chasing peak numbers. The dyno came back at 130 kW at the wheels with 353 Nm, which sits right where you'd expect for a naturally aspirated 6.0L in a heavy 4WD.
Fuel maps and ignition timing were adjusted for 98 RON. Throttle response cleaned up nicely, and the torque curve came through flat enough to make towing and loaded work straightforward without fuss.
Why stick with the factory ECU instead of a standalone for an engine swap?
The factory ECU keeps the build simpler and more cost-effective for a daily driver. It integrates with existing vehicle systems and provides reliable operation for touring and loaded work without the complexity of standalone management.
What supporting fuel system changes were needed for this swap?
A high-pressure fuel pump and upgraded injectors were fitted to match the L98's requirements. The calibration accounts for these changes to maintain proper air-fuel ratios on 98 RON.
Is 130 kW at the wheels typical for this engine configuration?
Yes, that figure is typical for a naturally aspirated L98 in a heavy 4WD with factory ECU control. The focus here is on a flat torque curve and reliability rather than peak output.
