Another clean R33 Skyline in for health check over and diagnose not running 100% low rpm

After tracing a few wiring issues and carrying out repairs, the customer opted to upgrade to a Link ECU G4X Plug-In ECU, along with a Link 3-port boost solenoid and Link CAN Lambda setup.

We also repaired the existing IAT sensor wiring, allowing us to convert the setup to a MAF-less tune with the Link ECU

Onto the dyno, where this RB25-powered setup delivered a healthy 448 BHP and 512 Nm torque 💥

Running an RB25 direct-fit hybrid turbo, this thing is now super responsive and drives exactly how it should 🔥

Added combined oil pressure & oil temperature sensor via Link expansion loom

Integrated existing AEM wideband gauge into the ECU system

Maf already removed and IAT added

📈 On the dyno (Dyno Developments rollers):

Nissan Silvia S14 for Link ECU

This clean S14 came to us for a management upgrade to unlock more from its SR20DET — and to future-proof it for a potential larger turbo setup.

We fitted a Walbro 255LPH fuel pump and a set of RB25 375cc injectors, with a solid intercooler setup already in place.
Next, we supplied and installed a Link G4X plug-in ECU, Link CAN Lambda, IAT sensor, and an AEM trigger wheel for precise control and reliability.

After mapping on the rollers, the car produced a healthy 300BHP and 421Nm — smooth, responsive, and ready for more power when the time comes 💪
