Small, but mighty!

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 expanded 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.

G4X features 512 megabytes of logging at 32bit using up to 250 channels, each limited to up to 1kHz per channel (by the Operating System), with a maximum of 100kHz.

G4X features 8 x faster communications speed, allowing you to download logs 8 x faster and pushes all the logging quickly up to a new and improved PCLink – available for download below in the features tab.

The AtomX can control up to 2 rotors or 4 cylinders with sequential injection and direct spark. This makes it ideal for naturally aspirated engines that just need a re-tune and don't need all the extra sensors and features that come with our higher level ECUs.

Requires "A" loom.

Features:

• 4 x high current injector drivers 
• 4 x ignition outputs
• 4 x auxiliary outputs (Unused ignition drives can be used as auxiliary outputs)
• 2 x digital inputs
• 2 x temperature inputs
• 3 x 0-5v Analog Inputs
• Boost Control 
• Wideband O2 (External controller required)
• 32Mb onboard logging
• Onboard diagnostics / channel test features
• 1 x thirty four pin, waterproof connector
  
  
  

Note1: The G4+ Atom X can not control the following

Launch / Anti lag

VVT Control

Electric Throttle

If you require these features please use the G4+ Monsoon, Storm, Fury, Extreme or Thunder Ecu
