3 MPS — Stage 3 ECU Tune
- 40% power increase to 165kW
- 70% torque increase to 267Nm
- Improved boost control management
- Enhanced drive-by-wire calibration
- Optimized fuel delivery mapping
- Superior turbocharger response
This 2010 MZR-DISI MPS was built for closed-circuit use with a GT3071R turbo on a freshly rebuilt bottom end. Supporting hardware includes a high-pressure fuel pump, direct injectors, and wastegate control to manage 1.72 bar of boost on 98 RON. The calibration focuses on durability and consistency rather than outright peak numbers.
The dyno result shows 174 kW at the wheels and 270 Nm torque—modest figures that reflect conservative boost and timing strategies to protect the rebuilt motor during extended track sessions. The tune prioritises stable boost delivery and fuel delivery headroom over chasing peak figures, which suits the intended use.
This file is calibrated on the factory ECU platform and intended for off-road competition environments where reliability under sustained load matters more than big dyno sheets.
Why are the power figures relatively low for a GT3071R setup?
The calibration is deliberately conservative to protect the rebuilt bottom end during sustained track use. Boost is held at 1.72 bar with timing and fuelling strategies that prioritise longevity over peak numbers.
Is this tune suitable for street use?
This is a Stage 3 build intended for closed-circuit competition only. The turbo, fuelling, and boost control are calibrated for track environments, not general road driving.
Does the factory ECU platform have enough headroom for this turbo?
Yes. The factory platform manages the GT3071R adequately with the upgraded fuel pump, injectors, and boost solenoids. The conservative tune strategy keeps demands well within the ECU's capability.
