The Link G4+ range of engine management systems are already well known for delivering class-leading performance without sacrificing factory levels of drivability.


The new Link G4+ Atom offers the power and flexibility of the G4+ platform at an entry level price.


Although, the little Atom is limited by the number of inputs and outputs it has, if the application doesn’t require these, then this ECU still delivers the flawless results that the G4+ models are known for.


With 4 injector drives & 4 ignition drives, this Link G4+ Atom ECU can run sequential injection and direct spark on a 4 cylinder engine. It can also run up to 12 cylinders using group-fire injection and a distributor or wasted spark (up to 8 cyl) ignition. The Link G4+ Atom has the following inputs and outputs:



  • 4 Injector Drives
  • 4 Ignition Drives
  • 4 Auxiliary Outputs (Fan, Boost control, idle speed control, etc.)
  • 3 User-configurable Analog Inputs (MAP sensor, wide-band O2, oil pressure, boost adjust knob, etc.)
  • 2 User-configurable Temperature Inputs
  • 2 dedicated trigger inputs
  • 2 User-configurable Digital Inputs



This is enough for many applications, but if you require more inputs and outputs, then we recommend either the G4+ Storm or G4+ Extreme.


G4+ ECUs do not require the use of an air flow meter. The engine can be converted to speed density using a MAP and intake air temperature (IAT) sensor (both available separately).


The Link G4+ Atom comes with a non-engine-specific base map. The ECU will need to be configured for the engine type and then tuned via the free software application PCLink.


The Link G4+ Atom comes with a USB tuning cable. In most cases the G4+ Atom can use all of the factory sensors except MAP and IAT.


Some of the additional features of the new G4+ Atom include:


  • Labelling of inputs and outputs
  • Metric / Imperial display at the push of a button
  • Twenty General Purpose tables (up from 12) and many dedicated tables



Dealer upgradable features (for additional charge):


  • 25 Channel logging
  • OBD2 upgrade which allows display of ECU parameters on a iPhone or Android phone.



A Loom kit must be purchased. Available in 400mm, 2.5m, 5m (NB: The G4+ Atom now uses the same loom that is used with the G4+ Storm, whereas the older G4 Atom used a loom specific to that model)


Once the installation is complete, the G4+ allows a good tuner to achieve an optimal state of tune to get the most out of any combination of modifications.
