Link ECU: G4X, G5 and plug-in ECUs

About Link ECU

Link makes two kinds of ECU. Wire-in units — the G4X XtremeX for up to eight cylinders, the FuryX for up to six, and the G5 Voodoo Neo 6 and Pro — need a harness built for the car. Plug-ins replace the factory ECU and use the factory harness, so nothing is rewired.

The plug-ins here fit the Nissan Skyline R32/R33/R34 GT-R, the 350Z and G35 with the VQ35DE, the S15 SR20, and the A80 Supra 2JZ (non-VVTi) — the platforms drift and track cars are built on.

Questions before you buy

Do I want a Link plug-in or a wire-in ECU?

If one of the plug-ins is made for your car, it is the simplest route: it plugs into the factory harness. A wire-in unit suits swaps, race cars and anything the plug-ins do not cover.

Is DEFI an authorised Link ECU dealer?

Yes. Every Link ECU unit here is sold at the price authorised dealers advertise, stocked in Corona, CA, and shipped free in the continental US. Alaska and Hawaii are quoted by phone.

Can you install and tune a Link ECU ECU?

Yes. We install, wire and calibrate Link ECU engine management in our Corona shop and tune it on a Mainline ProHub hub dyno, with the full sheet at the end. Shop labor is quoted against your car.

Can I return a Link ECU ECU?

No. There are no returns or exchanges on third-party hardware once it ships, and the manufacturer’s warranty is the warranty. Call before you order if you are not sure which unit fits.
