Commodore VE — Stage 3 ECU Tune
- Over 400kW at the wheels on conservative 7psi boost
- Effortless torque delivery with brutal top-end pull
- Safety and drivability optimized for premium fuel
- Factory-like off-boost manners with responsive performance
- Significant headroom for additional power with increased boost
- Reliable street machine capability with wild performance potential
This 2010 VE Commodore arrived already running a full single-turbo conversion on the L98. The brief was to dial in a solid calibration on 98 for track and competition use, managing boost at 0.48 bar through a pair of boost solenoids and drive-by-wire control.
The file focused on fuelling strategy to support the upgraded high-pressure pump and injectors, throttle mapping for predictable response under boost, and ensuring the factory ECU could handle the increased duty cycle reliably. Final numbers came back at 402 kW and 795 Nm at the wheels—a 2 kW lift in peak power with better torque delivery through the midrange.
It's a sorted street-registered track car now. The custom turbo system and S480 are well matched for the application, and the tune keeps everything stable on pump fuel for closed-circuit use.
Why only a 2 kW gain if it's a full Stage 3 build?
The car was already making 400 kW on a previous calibration. This file refined fuelling, boost control, and driveability rather than chasing peak numbers—it's about a usable, repeatable tune for track work.
Can the factory ECU handle this sort of output reliably?
With the right hardware—high-pressure pump, injectors, and proper boost control—the factory platform can manage these levels for competition use. Drive-by-wire mapping and fuel strategy are key to keeping it stable.
Is 0.48 bar conservative for an S480 setup?
It's appropriate for 98 RON and track reliability. The boost level balances power delivery with thermal management and component longevity on pump fuel.
