Regular price $1,374.00 Sale

The Link G4X AtomX ECU is the latest version of our entry-level ECU. Don’t let its size fool you however, the AtomX has 512 megabytes data logging and uses the same microcontroller as the entire G4X range! It is more responsive and has higher bandwidth that its G4+ Atom II predecessor.

The AtomX is ideal for:

  • 1-12 Cylinder Distributed
  • 2-8 Cylinder Wasted Spark
  • 1-4 Cylinder Direct Spark
  • Odd Fire Engines
  • 2-Stroke Engines
  • Configurable Firing Order
  • Configurable TDC Points (for odd fire) 

G4X Atom inputs:

  • 2 x Digital inputs
  • 2 x Temperature inputs
  • 3 x Analog inputs
  • 2 x Trigger inputs

G4X Atom outputs:

  • 4 x Injection drives
  • 4 x Ignition drivers
  • 4 x Auxiliary outputs
  • +5V Sensor power supply 

Link G4X ECUs do not require the use of an air flow meter. The engine can be converted to speed density using a MAP sensor and an intake air temperature (IAT) sensor (both sold separately).

The G4X Atom comes with a non-engine-specific base map. The ECU will need to be configured for the engine type and then tuned by a professional. The ECU comes with free PCLink software.


This Product is for the ECU only, this ECU requires a wiring Loom (A LOOM 2.5m long), depending on the application and the amount of outputs etc needed you may need a B loom as well (B LOOM 2.5m Long). 

We can also provide the following with your new Link ECU at an added cost:

- Fuel System Upgrades

- Turbosmart Wastegates, Blow off valves and Fuel Pressure Regulators

- Boost Control Solenoids

- Dyno Tuning

- Engine sensors and plugs etc

- Full Link ECU engine wiring installation available at an extra cost
