Link G4X AtomX ECU

Link G4X AtomX ECU – Compact Standalone Engine Management

Essential G4X performance in a compact wire-in ECU. The genuine Link G4X AtomX is designed for performance builds that need accurate fuel and ignition control without the expanded inputs, outputs and motorsport functions of a larger ECU. It is particularly well suited to four-cylinder applications and offers the same G4X processor, firmware and PCLink tuning environment used across the G4X range.

With four injection drives, four ignition drives, flexible engine protection and 512MB of onboard data logging, the AtomX provides a capable foundation for a properly planned engine management installation. It also supports flex-fuel strategies, CAN communication and compatible aftermarket displays.

Why Choose the G4X AtomX?

• Four-cylinder capability: controls up to four cylinders with sequential injection and direct spark, or up to two rotors in supported configurations.
• Flexible tuning: supports VE and traditional fuel modelling, individual-cylinder corrections, and dual fuel and ignition maps.
• Advanced logging: 512MB internal memory, up to 250 channels and a maximum total logging rate of 100kHz.
• Engine protection: configurable protection limiters and knock input for suitably configured monitoring and control.
• Connectivity: one CAN bus channel, Mini-B USB tuning connection, CAN keypad control and support for compatible aftermarket displays.
• Core G4X features: flex fuel, trigger oscilloscope, continuous barometric correction and open-loop boost control with up to three switchable tables.

Engine Compatibility and Applications

The AtomX supports up to four cylinders or two rotors with sequential injection and direct spark. It is intended for installations where its available inputs, outputs and control features meet the needs of the engine. It is a wire-in standalone ECU, not a universal plug-and-play replacement.

Before ordering, confirm your engine's trigger pattern, sensor requirements, ignition arrangement, wiring, desired functions and available inputs/outputs with your installer or tuner. Builds requiring expanded I/O or more advanced motorsport functionality may be better served by another Link ECU model.
