Falcon FG — Stage 3 ECU Tune
- 218% power increase to 226kW
- 113% torque increase to 508Nm
- Enhanced boost control capabilities
- Optimised fuel system management
- Drive-by-wire calibration refinement
- Improved throttle response and drivability
This FG runs a properly sorted bottom end and head combo paired with a large single turbo and Haltech engine management. The build leans into E85 for timing authority and detonation margin under boost, essential when you're pushing air through a ported head with aggressive cam timing. The workshop recorded 226 kW at the wheels with 508 Nm.
The calibration addressed fuelling across the entire load map, dialled in spark advance for the ethanol blend, and tuned the electronic boost control. With the TH400 behind it, this setup is intended for off-road and closed-circuit competition use where the extra torque and cooling headroom of E85 come into their own.
Why does this build only make 226 kW with such extensive modifications?
The power figure reflects what the workshop recorded at the wheels on their dyno. Dyno results vary widely based on the dyno type, correction factors, and ambient conditions. The 508 Nm torque figure suggests the tune was focused on drivability and reliability rather than chasing peak horsepower.
Is E85 hard to source in Australia?
E85 availability has improved in metro and regional areas, but it's still not as widespread as 98 RON. This fuel choice suits competition use where you can plan refuelling around known stations or bowsers at the track.
Can this calibration be adapted if I change the turbo or injectors?
No. The file is calibrated specifically for the hardware listed. Any changes to turbo size, injectors, or fuel system require a fresh base map and dyno session.
