The Link G4X MX5Link (#MX5-X) PlugIn ECU fits the Mazda MX5 1600-1800 (NA models) and the GTX/R (1800cc). The ECU PCB fits discretely inside the original factory enclosure. (Please note that this unit is only suitable for the 2 plug ECU and not the later 3 plug models).

Installation of Link's MX5 ECU is a breeze with no alteration of the factory wiring loom required.
A built-in connector (or pins in some models) provides additional inputs and outputs such as oil pressure inputs or anti-lag / logging switches.
Factory features are supported - see Features for any exceptions.
