Link G5 Voodoo Neo 4 is a 72-pin wire-in Link ECU on 3 connectors: A (34 pins), B (34 pins) and CAN1 (4 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: 2 throttles from its own H-bridge outputs. Two CAN buses handle dashes, PDMs and expansion.

Worth knowing
- 2 dedicated trigger inputs; further digital inputs take cam and VVT sensors.
- Injector drive type is not stated in Link's documents; the page says so.
Which builds it suits
Of the 58 swap presets in the planner, 10 fit as they are and 26 fit with add-ons; 22 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 RB26DETT (R34, smart coils), Honda K24 (i-VTEC 2.4 NA) and Mazda Rotary 13B-MSP Renesis (RX-8 auto, 4-injector) 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 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.
