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 G4x 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.
