Skyline R32 — Stage 3 ECU Tune
- Improved power output with 149% increase
- Enhanced torque delivery with 96% increase
- Optimized boost control
- Precision fuel system management on E85
- Advanced ECU calibration for forced induction
This 1990 R32 came in with a full Stage 3 build around the RB20: high pressure fuel pump, larger injectors, boost management via upgraded solenoids and wastegate, plus drive-by-wire conversion. The customer wanted a proper E85 calibration on the Link ECU to support reliable power for circuit use.
We dialled in fuel and ignition to suit the ethanol content and hardware, with the dyno showing 360 kW at the wheels and 490 Nm. The torque sits lower than you'd expect given the power, which is typical of a high-revving naturally smaller-displacement build when you're chasing top-end on E85. Calibration focused on stable AFRs under load and clean transitions through the boost curve.
This is a closed-circuit setup. The Link platform gave good control over the drive-by-wire and boost delivery, and the file reflects the ethanol's cooling benefit without getting greedy on timing.
Why is the torque relatively modest compared to the kilowatt figure?
The RB20 is a smaller-capacity engine that builds power higher in the rev range. That 360 kW comes from revs, not low-down grunt, so the 490 Nm torque figure reflects the engine's character rather than any limitation in the tune.
What does the drive-by-wire conversion add to a build like this?
It allows the Link ECU to manage throttle response electronically, which helps smooth out boost transitions and gives finer control over part-throttle drivability—useful when you're running serious power on a circuit.
Is this calibration suitable for street use on E85?
This is a closed-circuit competition file. While the hardware is capable, the calibration prioritises performance over the compromises you'd want for registered road use.
