Link G4X AtomX Essentials Package
For applications requiring a wire-in ECU, NZEFI saves you money and takes out the guess work with these Link G4X engine management packages.
This Link G4X AtomX Essentials package includes:
- Link G4X AtomX ECU
- 2.5m or 5m G4X Wiring Loom (‘Loom A’)
- Choice of one of two Inlet Air Temperature Sensors:
A.) Inlet Air Temp Sensor – 1/8″ NPT
B.) Bosch Fast Response Intake Air Temp (IAT)
- Choice of one of the four MAP sensor options:
A.) 1.15 Bar MAP Sensor (for naturally aspirated engines)
B.) 2.5 Bar MAP Sensor (for turbo engines up to approx 22 PSI of boost)
C.) 3.0 Bar MAP Sensor (for turbo engines up to approx 29 PSI of boost)
D.) 4.0 Bar MAP Sensor (for turbo engines up to approx 43 PSI of boost)
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 results that the G4X models are known for.
With 4 injector drives & 4 ignition drives, this Link G4X AtomX 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 G4X AtomX 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 or advanced functions such as continuously variable cam control or electronic throttle, then we recommend either the G4X StormX or G4X XtremeX.
Typical applications for the G4X AtomX Essentials Package are naturally aspirated, turbocharged or supercharged 4 cylinder engines including 4A-GE 16V, 4A-GE 20V, 4A-GZE, 3S-GE (except beams), 3S-GTE, B16A, B18C, H22A, Mazda B6 NA, SR20DE, SR20DET, SR16VE, SR20VE, EJ20, and EJ25 .
Note that for boost control on turbocharged engines we also recommend a boost control solenoid.
The Inlet Air Temperature Sensors come in either 1/8 NPT thread with alloy weld on boss or Single M6 bolt with weld on boss in the Bosch option. We recommend the Bosch option due to its robustness and Bosch Motorsport quality.
While the G4X StormX, FuryX(6 cyl only), XtremeX or G4+ Thunder ECU’s are recommended for 6 and 8 cylinder engines, lower budget 6 and 8 cylinder applications can use the AtomX with group fire injection and wasted spark ignition. This allows this package to be used in many instances on engines such as 1UZ-FE (except VVTi), 1JZ-GE (expect VVTi), 2JZ-GE (except VVTi), RB20, RB25, RB30, VG30, VQ30 , VH41, VH45, Holden Ecotec V6, Ford 4L I6, Ford V8, Holden V8, Chev LS1, LS2, LS3, L98, LS7, BMW M50, M52, S50, S52 plus many more. Note that some of these engines listed are factory fitted with electronic throttle. In this case, either a mechanical (cable) throttle can be retrofitted (allowing the AtomX to be used) or the electronic throttle can be retained by using the Link G4X FuryX, G4X XtremeX or G4+ Thunder ECU’s instead. Also note that some of these engines listed are factory fitted with 4 or 6 terminal stepper motors for idle speed control – stepper motors are not supported on the Atom, but they are supported on the higher end G4+/G4X wire in ECUs (i.e. all models except the AtomX and MonsoonX).
