S15 — Stage 3 ECU Tune
- 907kW peak power output
- Optimised turbocharger boost response
- Enhanced cylinder head flow characteristics
- Precision engine management and fuel delivery control
This 2001 S15 runs a full 2JZ conversion built for closed-circuit work, carrying a Garrett G42 turbocharger, Kelford cams, and extensive head porting. The Haltech Elite 2500 was mapped to manage the airflow and fuelling demands of a package designed to deliver 907 kW at the wheels and 1215 Nm of torque.
The calibration focused on maintaining stable combustion and fuelling accuracy through the upper reaches of the rev range, where heat and flow present the usual challenges. Ignition and VE tables were tailored to the ported head and cam profile, with lambda control tuned to suit the turbo's response. Suitable for dedicated track use where the drivetrain and cooling can support sustained high output.
What ECU platform was used for this build?
The car runs a Haltech Elite 2500 standalone ECU, which provides the flexibility needed to calibrate a high-output 2JZ swap with a large single turbo and supporting hardware.
Is this calibration file suitable for street use?
No. This is a full race build calibrated for closed-circuit competition use. The power output and supporting modifications are not intended for public roads.
What turbocharger was fitted to reach 907 kW?
The car uses a Garrett G42 turbocharger, paired with extensive head porting and Kelford camshafts to support the airflow required for this output level.
