The Link G4X RX7Link RX7S6X ECU is a plug-in standalone ECU designed specifically for the Mazda RX-7 FD Series 6 with the 13BT rotary engine. It fits inside the OEM ECU enclosure and connects directly to the factory wiring harness — no wiring modifications needed for supported vehicles.
This ECU is built for manual transmission cars only and supports a variety of engine setups, including naturally aspirated, parallel twin-turbo, or single turbo configurations. However, it does not support sequential control of the stock twin-turbo system. E-Throttle is supported only after hardware modification.
Note: Please ensure your ECU connector matches the product image before purchase.
