Link G5 Voodoo Pro V1 is a 94-pin wire-in Link ECU on 3 connectors: A (34 pins), B (34 pins) and E (26 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.

Worth knowing
- This is the Voodoo Pro V1, superseded by the V2.
- 16 injector or 12 ignition: 4 drives are shared between injection 13-16 and ignition 9-12.
- CAN 1 is on the 6-pin round connector; CAN 2 on E5/E6.
- Injector drive type is not stated in Link's V1 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 LS L76 (Gen4 6.0 alum), Nissan VR38DETT (R35 GT-R), Subaru EJ/FA EJ20 turbo single-AVCS (EJ207 v7-9) and Mazda Rotary 13B-MSP Renesis (RX-8 auto, 4-injector) presets with nothing added. The GM LT1 (Gen5 6.2 alum) needs a direct-injection driver module. The Nissan RB25DET non-Neo S1 (R33, dumb coils) needs an external igniter. It can't run the BMW S54 (3.2 NA I6, E46 M3): not enough knock inputs.
