FT86 — Stage 3 ECU Tune
- Increased power output to 135 kW
- Supercharger forced induction
- Enhanced engine performance
- Optimized fuel delivery mapping
- Improved throttle response
The FA20 responds well to forced induction when the fuelling and calibration catch up. This 2014 FT86 came through with a stage 3 supercharger kit and bolt-ons already fitted, needing a proper calibration to tie it all together for reliable operation on track and weekend drives.
The tune focused on keeping the torque curve predictable and managing heat in extended use—critical for a platform that sees plenty of closed-circuit work. Final numbers landed at 135 kW and 205 Nm at the wheels, measured post-tune by the workshop. Not chasing headline figures, but a clean, repeatable result that suits the car's lightweight chassis and RWD layout.
Throttle response stayed sharp without any part-throttle stumbles, and the calibration accounts for Australian summer conditions where inlet temps climb quickly during spirited driving.
What makes the FA20 suitable for supercharging at stage 3?
The FA20's square bore and stroke handle boost well when supported by appropriate fuelling and calibration. This setup included a stage 3 supercharger kit with necessary bolt-ons, allowing reliable power delivery for track and road use without compromising drivability.
Is 135 kW at the wheels typical for a stage 3 supercharged FT86?
Output depends heavily on the specific supercharger kit, fuel type, and calibration goals. This result reflects a conservative, repeatable tune suited to extended use rather than peak numbers on a single pull.
Can this calibration handle varying fuel quality?
The tune was developed to account for real-world conditions, including heat and fuel variability. For best results, consistent fuel quality is always recommended, particularly with forced induction.
