The Link G4X XtremeX is one of Link ECU’s premium standalone engine management systems, designed for serious street, track, and professional motorsport applications. With expanded inputs, outputs, advanced motorsport strategies, and built-in electronic throttle control, the XtremeX is ideal for high-performance builds that need more flexibility and control than entry-level ECU options.
With 8 injector drives and 8 ignition drives, the XtremeX can control up to 8-cylinder engines or 4-rotor applications with sequential injection and direct spark. It also includes advanced features such as anti-lag, launch control, traction control, cruise control, gear shift control, closed-loop lambda strategies, dual CAN communication, and onboard data logging.
