Link MX5Link G4X Plug-In ECU - Mazda MX-5 (NB2X) MY2001-2005

Link Engine Management builds its G4X Plug-In ECUs to bolt straight into the factory ECU enclosure, giving tuners full standalone control without hacking apart the original wiring loom. For the Mazda MX-5 (NB2X), this means genuine engine management upgrade potential with a factory-level install process. SKU 239-4000.

This listing covers the facelift Mazda MX-5 NB2X, built MY2001-2005, including naturally aspirated VVT engines and the non-VVT Mazdaspeed 1.8L turbo variant. Check your factory connector matches the header shown in the listing photos before ordering.

Important: this ECU supports manual transmission vehicles only. It is not compatible with automatic NB2X models. CAN devices require the new CANJST4 (Link PN 101-0198) cable, as the older CANPCB cable will not work with this unit's 4 pin powered CAN connector.
