Link G4+ Fury pinout and specs

Link G4+ Fury 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 peak-and-hold, so low-impedance injectors run without a resistor pack. 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.

It has H-bridge outputs labelled for an electronic throttle, so drive-by-wire runs from the ECU itself. 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'.

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 Toyota 1JZ-GE distributor (NA, early) needs an external igniter. The Nissan VR38DETT (R35 GT-R) needs Link CAN-Lambda. It can't run the GM LS6 (Gen3 5.7 alum): not enough ignition outputs. It can't run the GM LT1 (Gen5 6.2 alum): not enough ignition outputs. It can't run the Ford Modular 5.4 4V Ford GT (S/C, cable): not enough ignition outputs.
