Skyline R33 — Stage 2 ECU Tune
- 380kW power output delivery
- Enhanced boost management and stability
- Improved fuel system reliability
- Optimised intercooler cooling efficiency
- Superior clutch engagement and holding capacity
- Smooth and reliable power delivery across RPM range
This R33 runs a proper Motec M150 package with a single GTX mid-frame turbo doing the work. Workshop recorded 380 kW at the wheels and 542.3 Nm after the tune settled in. The single-turbo conversion keeps spool manners predictable and the M150 gives you the resolution you need when you're chasing clean transients and stable closed-loop fuel control on these RBs.
Upgraded fuel system was already in place to support the output, and the twin-plate clutch handles the torque without the pedal feel turning into a leg press. Calibration focused on safe ignition timing through the mid-range and clean fuel delivery at the top end, keeping it reliable for circuit use.
Built for closed-circuit competition, not street registration.
Why step up to a Motec M150 on an RB26?
The M150 gives you proper programmability and much finer control over ignition, fuel, and boost maps than the factory ECU or older piggybacks. Critical when you're pushing this sort of power and want repeatable, safe results on track.
How does a single GTX compare to the factory twins?
You lose some of the bottom-end response the twins give you, but gain top-end flow and simpler plumbing. Midrange spool is still strong with the right housing choice, and there's less heat and fewer failure points.
What fuel would this calibration suit?
Fuel type wasn't recorded with this file, but at 380 kW you'd typically be on E85 or race fuel. Confirm with your tuner before loading.
