Link G5 Voodoo Neo 6 pinout and specs

Link G5 Voodoo Neo 6 is a 72-pin wire-in Link ECU on 3 connectors: A (34 pins), B (34 pins) and CAN1 (4 pins).

It has 12 injector outputs and 8 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

  • Injectors 9-12 share pins with DI 7-10.
  • 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 47 fit with add-ons; 1 does not fit at all. The add-on it asks for most often is the Link CAN-Lambda. Where it falls short, it is usually not enough knock inputs. 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), Honda K20 (i-VTEC 2.0 NA) and Mazda Rotary 13B-MSP Renesis (RX-8 manual, 6-injector) presets with nothing added. The Ford Coyote 5.0 Gen1 (2011-14) needs Link CAN-Lambda and an external igniter. The Subaru EJ/FA EJ25 turbo dual-AVCS (EJ257 2008+) needs Link CAN-Lambda. It can't run the BMW S54 (3.2 NA I6, E46 M3): not enough knock inputs.
