Link G4X StormX ECU
The G4X StormX is Link’s mid-sized performance ECU, offering advanced tuning features at an affordable price. It supports sequential injection and direct spark for up to 8 cylinders or 4 rotors and includes powerful features like onboard Knock Control, Boost Control, and advanced motorsport functions such as Full Gear Shift Control, Antilag, and Launch Control.
With expanded data logging, a built-in trigger oscilloscope, and faster USB communication, the StormX is a significant upgrade over the G4+ Storm. It’s ideal for high-performance builds that demand flexibility and control — without stepping up to the Xtreme or Fury models.
Requires “A” & “B” looms or connector kits (sold separately).
Note: For traction control, peak & hold injectors, or e-throttle, consider the XtremeX or FuryX models.
