GT-R R35 — Stage 1 ECU & TCU Tune
- 25% power increase to 360kW
- 18% torque increase to 547Nm
- Four switchable performance maps
- Variable boost control via cruise stalk
- Refined transmission calibration for smoother shifts
- Rolling anti-lag and launch control enabled
This 2008 R35 GT-R arrived with a cat-back exhaust already fitted, and the brief was simple: extract what the VR38 had left on the table without touching hardware. Using ECUTEK for both ECU and TCU, we recalibrated ignition, fuel, boost solenoid duty and fuelling to suit 98 RON. The result was 360.2 kW at the wheels, up from 288.5 kW, a gain of 71.7 kW. Torque lifted from 464 Nm to 547 Nm.
The TCU calibration raises clutch line pressure and clutch torque limits and refines gearshift torque reduction, which suits circuit work where the GR6 dual-clutch gearbox benefits from decisiveness. A solid Stage 1 result on pump fuel without bolting anything new onto the car. Tuned for off-road and closed-circuit use.
Does this tune require any hardware changes?
No. This is a Stage 1 software calibration. The vehicle had a cat-back exhaust already fitted, but no other modifications were required.
What does the TCU calibration change?
The GR6 is a dual-clutch gearbox, so there is no torque converter to lock up: clutch line pressure and clutch torque limits are raised to hold the extra torque, and gearshift torque reduction is refined so shifts stay smooth under load.
Is this safe on 98 RON pump fuel?
Yes. The calibration was developed and validated on 98 RON, with fuelling and ignition timing mapped accordingly.
This calibration was developed for a workshop like yours
The Nissan GT-R above was calibrated by Protunes for a partner workshop — they did the vehicle work and kept their customer; we did the calibration engineering on the ECUTEK. Add professional ECU and TCU calibration to your workshop without employing a calibration engineer.
