Link ECU | "G4X AtomX"

  • The Link G4X AtomX ECU is one of the latest versions of Link Engine Management's entry level ECU modules. It's more responsive and has higher bandwidth than it's predecssor, the Link G4+ Atom II, as well as using the same microprocessor as the entire G4X range.
  • This module features 512MB of data logging at 32bit using up to 250 channels, each limited to 1kHz per channel, with a maximum of 100 kSamples/sec.
  • The Link G4X AtomX can control up to two (2) rotors or four (4) cylinders with sequential injection and direct spark. It can also be used for up to 8 cylinders with batch fire. Ideal for naturally aspirated engines with no use for all the extra sensors than come with Link's higher level ECU modules.
