Show original supplier description
The Link ECU MX5LINK is a G4X Plug-In ECU offering the latest in engine management technology, designed for easy installation and to maximize the potential of your vehicle. This unit fits directly inside the factory OEM enclosure, requiring no alterations to the original wiring loom for compatible models. Specifically engineered for the Pre-Facelift Mazda MX5 NB, model years 1998-2000, equipped with the non-VVT 1.8L engine and a 3-plug ECU connector. It is exclusively compatible with manual transmissions. The ECU features an integrated 7-bar MAP sensor and supports most factory features, with options for I/O expansion available. This Plug-in ECU utilizes a new 4-pin powered CAN connector. It requires the CANJST4 cable (Link PN 101-0198) for connecting CAN devices, as the older CANPCB cable is not compatible. The new 4-pin port and cable provide CAN connectivity along with a protected 12V power supply and ground for CAN devices, protected by a 3A continuous self-resetting fuse.
