Haltech Nexus Plug-in ECU – Mazda RX-8 – Whitey's Wiring, Brisbane
This Haltech plug-in replaces the factory ECU in the Mazda RX-8 and its RENESIS rotary, plugging straight into the factory loom for a clean install with full standalone control.
We've been a Haltech dealer for over 10 years and dyno tune Haltech installs at our Clontarf workshop. We can help you plan the supporting parts, like wideband, flex fuel or a dash.
