Link JZX90X G4X PlugIn ECU Toyota Chaser/Cresta/Mark II (JZX90)

Link JZX90X G4X PlugIn ECU - Toyota Chaser/Cresta/Mark II (JZX90)

Link Engine Management's G4X PlugIn ECU (SKU 235-4000) brings modern engine management to the Toyota JZX90 platform, dropping straight into the factory OEM enclosure with no cutting or rewiring of the original loom. It's a reliable, affordable way to unlock proper tuning control from the 1JZ-GTE while keeping installation simple.

This listing covers the Toyota Chaser, Cresta and Mark II (JZX90) fitted with the 1JZ-GTE (Non-VVTi) engine, as well as the Toyota Soarer (JZZ30) running the same engine. Both applications require a manual transmission.

Important: This ECU is designed for manual transmission vehicles with the 1JZ-GTE Non-VVTi engine only. Confirm your factory connector matches the header shown in the listing photos before ordering, as fitment varies across sub models.
