Link G5 Voodoo Pro V2 pinout and specs

Link G5 Voodoo Pro V2 is a 98-pin wire-in Link ECU on 4 connectors: A (34 pins), B (34 pins), E (26 pins) and CAN1 (4 pins).

It has 16 injector outputs and 12 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 2 onboard wideband controllers, 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. Four outputs can switch 12V as well as ground. The maker rates the 5V sensor supply at 400 mA in total.

Worth knowing

  • 12 injector + 8 ignition + 4 drives that can be either.
  • 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, 28 fit as they are and 29 fit with add-ons; 1 does 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 knock inputs. The planner fills anything a preset leaves open with its ordinary defaults, so your own build may land differently.

It runs the GM LS6 (Gen3 5.7 alum), GM LSA (Gen4 6.2 alum, S/C), Nissan VQ35DE Rev-Up (2005-06) and Subaru EJ/FA EJ25 turbo dual-AVCS (EJ257 2008+) presets with nothing added. The Toyota 2JZ-GE distributor (NA, early) needs an external igniter. The Ford Coyote Predator 5.2 (GT500, cross-plane, S/C) needs an external igniter. It can't run the BMW S54 (3.2 NA I6, E46 M3): not enough knock inputs.
