Silvia S14 — Stage 1 ECU Tune
- 71% power increase
- 78% torque increase
- Improved boost control
- Enhanced fuel system responsiveness
- Optimised engine management calibration
This S14 came in with the usual supporting mods already fitted: exhaust, boost control via wastegate solenoids, high-pressure fuel pump, and injectors. The goal was straightforward — get the most out of the hardware without chasing big numbers or needing a larger turbo.
Calibrated on the Link G4x platform using 98 RON, the file brought it from 76 kW to 130 kW at the wheels, with torque lifting from 122 Nm to 218 Nm. The workshop recorded the results after a few iterations to dial in fuel pressure and boost stability. Clean powerband, no heroics — exactly what you'd expect from a well-sorted SR20 on a proven standalone.
Intended for closed-circuit and off-road competition use.
Does this file require any hardware changes beyond what's listed?
No. This is a Stage 1 software-only tune built for the modifications already fitted: exhaust, boost controller, wastegate solenoids, high-pressure fuel pump, and injectors.
What ECU platform was used for this calibration?
Link G4x standalone. The file is supplied ready to load for workshops running the same ECU on similar S14 SR20 builds.
Is this suitable for street use?
This calibration is intended for off-road and closed-circuit competition use only.
This calibration was developed for a workshop like yours
The Nissan Silvia 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 Link ECU G4x. Add professional ECU and TCU calibration to your workshop without employing a calibration engineer.
