G5 Voodoo
G5 Voodoo is Link's premium platform for advanced engines that require direct injection, high injector, input or output counts, or advanced processing and communication.
We recommend G5 if you are running direct injection*, 2-stage injection, have a high input or output requirement, or want features like GPS, Ethernet and Wi-Fi.

G4x
Link's race-proven power house, G4X has a very modern architecture that is great value, easy to install and highly reliable.
G4X is still the platform we recommend for a wide range of applications. It is the go-to solution for all the engines and builds it currently supports, and will be manufactured and fully backed for years to come.

The table is going to need the following footnotes somewhere, preferably at the bottom:
‡ G5 Voodoo Pro has 12 inj, 8 ign, plus 4 multipurpose (inj, ing, aux) drives (24 total). † Check Specific pinout for number of I/Os exposed.
† Check Specific pinout for number of I/Os exposed.
# 4 pins are multi-purpose Aux or Digital Input pins. Each pin can be either Aux or Digital Input, not both at the same time.
* 2 Digital Inputs required when using 2nd CAN Bus.
§ 4 pins are multi-purpose Injection, Aux or Digital Input pins. Each pin can be either Injection, Aux. or Digital Input, not all at the same time.
Link ECU products should not be used where they interfere with a vehicle’s safety or emission control features. (no footnote symbol on this one).
Plug-in features and specifications shown are indicative of G4X Plug-in ECUs only and vary by application. For full features and specifications, refer to the specific product page.
Next Steps
Link ECU's offer better customization, performance tuning, and support for mods compared to OEM ones.
These steps help you choose the right ECU and maximize its features.
