Link G4X AtomX ECU – Small in size, big in performance
The Link G4X AtomX ECU is the latest version of our entry-level ECU, delivering powerful performance in a compact design. Don’t let its size fool you – the AtomX features comprehensive data logging and utilises the same powerful microcontroller as the entire G4X range, resulting in faster responses and higher bandwidth than its predecessor, the G4+ Atom II.
Extensive data logging and lightning-fast communication
The G4X AtomX offers 512 megabytes of data logging with 32-bit logging on up to 250 channels, each at up to 1 kHz. With a maximum rate of 100 kSamples/second and 8 times faster communication, log files can be quickly downloaded and analyzed using the latest version of PCLink software.
Powerful engine management options
This ECU can control up to 4 cylinders with sequential injection and direct ignition, or up to 8 cylinders with batch injection. In addition, the AtomX is equipped with Knock Control, making it ideal for naturally aspirated engines that only require a tune-up, without the additional sensors and features of higher-end ECU models.
Technical specifications
- Inputs: 2 digital inputs, 2 temperature inputs, 3 analog inputs, 2 trigger inputs, and 1 knock input.
- Outputs: 4 injector controls, 4 ignition outputs, 4 auxiliary outputs (extra aux connections for unused ignition wires).
- Communication: 1x CAN bus and USB tuning connection.
- Additional features: Advanced data logging (512MB), built-in Knock Control and versatile configuration options.
Easy to install
The AtomX comes with an "A" loom (sold separately), and includes a USB tuning cable, mounting bracket, and a set of Link ECU stickers. The easy-to-use PCLink software allows you to adjust all parameters in real-time, and offers powerful setup options such as fuel and ignition maps with up to 440 zones for precise tuning.
