Link G4X AtomX ECU
Compact Yet Powerful
The Link G4X AtomX ECU is the latest version of Link’s entry-level engine control unit, offering improved responsiveness and expanded data logging. Despite its small size, it utilizes the same high-performance microcontroller as the entire G4X range, delivering enhanced speed and bandwidth compared to the G4+ Atom II.
Key Features
- Advanced Data Logging – 512MB of 32-bit logging, supporting up to 250 channels at a maximum of 100 kSamples/sec.
- Fast Communication – 8x faster communication speeds allow for quicker log downloads via a mini USB connection.
- Engine Compatibility – Supports up to 2 rotors or 4 cylinders with sequential injection and direct spark, or up to 8 cylinders in batch fire mode.
- Knock Control – Now included to enhance tuning and engine safety.
- Ideal for Tuned NA Engines – Designed for naturally aspirated setups needing tuning without additional sensors and features of higher-tier ECUs.
