Link ECUs Australia | Plug-In & Universal ECUs, Sensors and Accessories

Link G4X PlugIn ECU coverage includes the Honda S2000 (AP1/AP2), the Toyota Chaser/Cresta/Mark II (JZX90), and the Mazda MX-5 (NB2X, MY2001-2005) via MX5Link. Each plug-in ECU uses the factory connectors, so there's no need to cut the original engine loom. For anything outside these three plug-in platforms, a wire-in G4X build with universal accessories is the usual route.

• Plug-in ECUs: Link G4X units built for specific factory connectors, currently covering S2000, JZX90 and MX-5 NB.
• Wiring and expansion: CANJST CAN connection cable, CANTEE CAN splitter cable, and the G4+ XS expansion loom for adding inputs and outputs.
• Sensors: Link 4 Bar MAP sensor and universal inlet air temp sensor (1/8 BSPT) for boosted and naturally aspirated setups.

Link has built its reputation in New Zealand and Australia on ECUs that are genuinely tuner-friendly, with PC Link software that doesn't require a factory dealer network to access. The G4X generation adds more processing power, more inputs and outputs, and a cleaner CAN bus setup compared to the older G4+ range, which is why Chicane carries G4X as the current plug-in standard while still stocking G4+ compatible accessories like the XS expansion loom for existing G4+ owners. Plug-in ECUs suit owners who want factory-style reliability and a tidy engine bay, while wire-in builds suit swapped engines or heavily modified cars where a bespoke loom is already part of the plan.

Plug-in ECUs like the S2000 unit, the JZX90X, and the MX5Link G4X are designed to connect directly to the factory engine harness, which keeps the install closer to a factory ECU swap than a full rewire. Confirm chassis code and model year before ordering, since AU-delivered variants and factory connector revisions can differ between production years even within the same model name. A wire-in setup needs a compatible loom, the correct CAN cabling if running multiple Link-compatible devices such as a CAN keypad or dash, and sensors matched to the engine's boost and airflow range, which is where the 4 Bar MAP sensor and inlet air temp sensor come in. Most installers will also want a genuine tuning file or a qualified tuner booked in before the car goes anywhere near a dyno, since a standalone ECU is only as good as the map loaded into it.

• DIXCEL brake pads and rotors for cars gaining power and needing to stop harder
• Fuel system components to match injector and pump sizing to a new Link tune
• Engine management and electrical for related sensors, harnesses and gauges

Does the G4X plug-in ECU fit my exact model year? Plug-in fitment is model and chassis specific. Check the year range listed against your vehicle's build plate before ordering, particularly for AU-delivered cars with different equipment levels.

Can I use G4+ accessories with a G4X ECU? Some accessories, like the G4+ XS expansion loom, are specific to G4+ hardware. Check compatibility against your ECU generation before assuming a part will work across both ranges.

Do I need a tuner after fitting a Link ECU? Yes. A standalone ECU needs a base map and a proper tune to run safely and make good power, so factor a qualified tuner into the project alongside the hardware.

What's the difference between the CANJST and CANTEE cables? The CANJST is a CAN connection cable for linking a G4X/G4+ ECU to a compatible CAN device, while the CANTEE is a splitter cable for running multiple CAN devices off the one bus.

Does Chicane ship Link ECUs and accessories Australia-wide? Yes, all Link products listed here ship across Australia.
