Monaro CV8 — Stage 3 ECU Tune
- Enhanced boost control at 7psi
- Improved fuel efficiency
- Increased power output
- Elevated torque delivery
- Optimized wastegate management
- Refined fuel system calibration
The Monaro remains one of the most straightforward platforms for forced induction on 98 RON, and this CV8 demonstrates exactly that. With a Harrop positive-displacement blower sitting at 0.48 bar, the factory LS1 ECU handles fuelling and timing once the injector and pump flow is sorted. Drive-by-wire throttle response was sharpened to suit boost delivery.
Dyno numbers landed at 311 kW and 541 Nm at the wheels, well within safe margins for street-bred bottom end when boost is kept modest and fuelling is tight. Calibration focused on part-throttle driveability and maintaining a clean AFR curve through the midrange, where most of the real-world work happens.
Intended for closed-circuit use. The factory ECU holds up surprisingly well with the right supporting hardware and a disciplined boost ceiling.
Can the factory LS1 ECU handle a positive-displacement supercharger like this?
Yes, with upgraded injectors, high-pressure fuel pump, and proper calibration. The factory ECU manages timing and fuelling effectively at 0.48 bar when hardware flow matches demand.
What's the safe limit for boost on a stock bottom end LS1?
This build sits at 0.48 bar on 98 RON with conservative timing, which leaves headroom. Higher boost typically requires stronger internals, especially for sustained use.
Is drive-by-wire response an issue with forced induction?
It can be. This calibration includes throttle mapping optimisation to sharpen response and eliminate lag between pedal input and boost delivery.
