Link MR2Link V3 - Toyota MR2 (SW20) / Celica (ST205) - TST205X
Free yourself from the limitations of the factory ECU. Link is one of the most trusted names in aftermarket engine management, and the G4X MR2Link V3 brings fully programmable control to the Toyota MR2 and Celica platforms without the hassle of rewiring the factory loom.
This listing covers the Toyota MR2 (SW20) and Toyota Celica (ST205). The Link ECU PCB is engineered to fit discreetly inside the original factory ECU enclosure, so the plug in loom, connectors, and factory harness are retained with no cutting or splicing required.
Note: This ECU does not include a MAP sensor, so confirm you have a suitable sensor on hand or budget for one separately before installation.
