The Link G4X AtomX is a compact, entry-level standalone wire-in engine management unit built for four-cylinder and single-rotor applications. Despite its small footprint, the AtomX delivers the core tuning capabilities of the G4X platform — sequential fuel injection, direct spark control, and 512MB of onboard data logging at 32-bit resolution.
The AtomX runs on Link's PC Link tuning software, giving you access to professional-grade mapping tools, real-time data viewing, and logging analysis. It supports up to four fuel and four ignition drives, making it an ideal solution for naturally aspirated or lightly boosted builds where I/O count is not a limiting factor.
