Link G4X FuryX is a 70-pin wire-in Link ECU on 3 connectors: A (34 pins), B (34 pins) and CAN (2 pins).
It has 8 injector outputs and 6 ignition outputs. The injector drivers are saturated, which means high-impedance injectors. Low-impedance ones need a ballast resistor pack or a different ECU. The ignition outputs are logic-level. Smart coils plug straight in; dumb coils need an igniter in between.
There are 2 dedicated trigger inputs, each happy with a VR or a Hall sensor. Two knock inputs cover both banks of a V engine. It has an onboard wideband controller, so a sensor wires straight in.
Drive-by-wire is native: 1 throttle from its own H-bridge outputs. Two CAN buses handle dashes, PDMs and expansion. Four outputs can switch 12V as well as ground.

Worth knowing
- Digital inputs: 10, of which DI 9/10 share pins with CAN 2.
- Onboard MAP: Link does not list one for this model, so the page says 'not listed' rather than 'no'.
- Ignition type is read across from Link's G4 family wording (ignition amplifier drivers).
Which builds it suits
Of the 58 swap presets in the planner, 8 fit as they are and 26 fit with add-ons; 24 do not fit at all. The add-on it asks for most often is an external igniter. Where it falls short, it is usually not enough ignition outputs. The planner fills anything a preset leaves open with its ordinary defaults, so your own build may land differently.
It runs the Nissan RB25DET Neo (R34), Nissan SR20DET (S15), Honda K24 (i-VTEC 2.4 NA) and Mazda Rotary 20B (Eunos Cosmo 3-rotor) presets with nothing added. The Nissan RB20DET needs an external igniter. The Subaru EJ/FA FA20D (BRZ/86 NA) needs Link CAN-Lambda. It can't run the GM LS LY6/L96 (Gen4 6.0 iron): not enough ignition outputs. It can't run the Ford Modular 4.6 4V Cobra (NA, cable): not enough ignition outputs. It can't run the BMW S54 (3.2 NA I6, E46 M3): not enough knock inputs.

Other Link ECUs
The closest Link unit is the Link G4+ Fury. Against it, this one has saturated injector drive (the G4+ Fury is peak-and-hold) and 1 drive-by-wire channel (the G4+ Fury has none).
