Link G4X XtremeX ECU - Universal
The Link G4X XtremeX is one of Link's flagship ECUs, built for tuners who need maximum inputs, outputs and control. SKU 109-4000. It packs in built in E-throttle along with advanced features like anti-lag, cruise control and traction control, making it a serious option for professional motorsport builds and demanding road cars alike.
This listing covers the standalone G4X XtremeX ECU unit, suited to universal fitment across a wide range of engine platforms. With 8 injector drives and 8 ignition drives, it can run sequential injection and direct spark on engines up to 4 rotors or 8 cylinders.
Note: This ECU requires both "A" and "B" wiring looms for installation, sold separately. If you need peak and hold injector drive support, the G4X XtremeX does not offer this — you'll need to speak with a Link ECU specialist about the G4+ Xtreme instead.
