Evo 9 — Stage 2 ECU Tune
- Near 400kW power output at 26lbs boost
- Enhanced airflow with MIVEC variable cam timing
- Improved turbocharger response with GTX3076R
- Upgraded intercooling efficiency
- Reinforced bottom end with H-beam construction
- Extended driveline durability with OEM 6-speed transmission
This 2006 Evo 9 is a proper circuit weapon. The built bottom end on H-beams provides the foundation for serious boost, with the GTX3076R pushing 1.79 bar through an upgraded intercooler and fuel system. Kelford 272 cams work with the factory MIVEC system, and the ignition system upgrade keeps timing sharp at higher cylinder pressures.
The Link G4+ standalone gave us full control over cam timing, boost targets, and ignition strategy. Workshop dyno figures came in at 394 kW and 565 Nm at the wheels, up from 315 kW and 525 Nm on the previous tune. The curve is clean and holds strong through the upper midrange where these engines can fall off if the cam timing isn't dialled properly.
This calibration is intended for closed-circuit competition use. The built motor handles the load, but longevity depends on maintenance intervals and operating conditions.
Why the GTX3076R on a built 4G63?
It's a good match for a 2.0-litre that needs quick spool but can sustain boost to redline. The 79 kW gain shows it's sized right for the engine and supporting mods.
What does the Link G4+ offer over factory ECU on this platform?
Full control over MIVEC cam timing, individual cylinder tuning, flex fuel capability, and proper traction and boost control strategies. Essential when you're running this far beyond factory spec.
Is 1.79 bar safe on a built 4G63?
With H-beam rods, upgraded fuel and ignition, and proper calibration, yes. The engine is designed for sustained high-load operation on track, not street use.
