Advanced Performance Tuning: LINK Engine Management

G4 Atom - Entry Level Engine Management

The G4 Atom is Link's entry level ECU that blows the opposition away - half the size, all the technology!
The all new G4 atom is your entry level ECU that blows the opposition away.
Full configurability, no preset inputs / outputs. Logging, motorsport, even closed loop fuel and knock if external devices are added. Industry standard waterproof connectors, mounting bracket and loom, all supplied with your G4 Atom.
