Link G4X RX7Link (S7) RX7S7X Plug-in – Whitey's Wiring, Brisbane

This Link G4X plug-in replaces the factory ECU in the Mazda RX-7 FD Series 7 and plugs straight into the factory wiring loom, with no cutting or re-pinning. It gives you full standalone control of your 13B-REW engine, ready for more boost, bigger injectors, flex fuel and motorsport features like launch control.

As a Link dealer for over 10 years, we know these plug-ins well and dyno tune them at our Clontarf workshop. If you're planning more boost, flex fuel or motorsport features, we can help you plan the supporting parts.
