The MiataLink (MX5X) is Link Engine Management’s G4X plug-in ECU for the Mazda MX5 NA (Miata / Eunos Roadster) with the B6ZE 1.6L or BP 1.8L engine. The PCB fits inside the factory ECU enclosure with no loom modification. An onboard 4-bar MAP sensor is built in.
Important: The MiataLink MX5X fits the NA-chassis MX5 with the 2-plug OEM ECU header only. It does not fit the NB MX5 (3-plug ECU), NC, or ND. Check that your car has a 2-plug ECU before ordering.

Frequently Asked Questions
Does the MiataLink fit NB MX5 models?
No. The MiataLink MX5X is for the NA-chassis MX5 with the 2-plug ECU header only. The NB MX5 uses a 3-plug ECU header and requires a different product.
Is a base map included?
Yes. A startup base map is pre-loaded for the B6ZE and BP engines. Professional dyno tuning is required before use.
Backorder Products
These items aren't kept in stock but are available for purchase.
Sensor connectors and Deutsch DT/DTM/DTP connector kits sometimes are listed as Backorder items, but we stock seperate items, so it only takes to collect these for your shipment in kits.
