Link are redefining what an entry level ECU should be.


The Atom now comes in a brand new enclosure, beautifully crafted from glass filled nylon.
The stylish new enclosure is designed to IP67 standards, making it dust and waterproof.

Running on the proven Link G4+ platform and being completely waterproof,
Link are redefining what an entry level ECU should be.


The Atom is ideal for naturally aspirated engines with 4 cylinders or less that just need a repower and don’t need all the extra sensors and features that come with our higher level ECUs.
