VZ Crewman VZ — Stage 2 ECU Tune
- Power output increased to 360kW
- Enhanced forced induction from supercharger installation
- Improved airflow through header and exhaust modifications
- Optimized ECU calibration for supercharged operation
- Increased overall engine performance and response
The VZ ute platform responds well to forced induction, and this '06 Crewman with a 6.2L V8 and Harrop supercharger is a solid example. Workshop supplied dyno figures showed 360 kW and 770 Nm at the wheels after the Stage 2 calibration was dialled in. The build includes a camshaft upgrade, headers, and a full exhaust—foundation work to make the most of positive displacement boost.
Calibration focused on fuel delivery under boost, ignition timing across the load range, and keeping the supercharger happy without leaning on timing pull to stay safe. With this kind of output, it's intended for closed-circuit or off-road competition use. The platform handles it well once the supporting hardware is sorted.
What fuel would this calibration typically require?
With a supercharged 6.2L making this kind of power, 98 RON pump fuel is the baseline, though E85 is often preferred for better charge cooling and knock resistance under sustained load.
Is 360 kW reliable on the VZ platform?
With proper supporting mods—cam, headers, exhaust, and a quality supercharger kit—the 6.2L platform can handle it. Calibration and regular maintenance become critical at this output level.
Can this tune be used on the street?
This calibration is intended for off-road and closed-circuit competition use only, given the power level and forced induction setup.
