Description

The Link G4X Mazda RX7 S6 Plug-In ECU is an advanced engine management system that offers the latest technology to help you maximize your car's performance. Designed as a plug-in unit, it fits directly into the factory OEM enclosure, simplifying installation by eliminating the need for any modifications to the factory wiring loom. This ECU is engineered specifically for the RX7 series 6 13BT engine. This ECU is compatible with manual transmissions only. It supports naturally aspirated, parallel twin, or single turbo configurations for the FD3S Series 6 RX7. However, it does not support the sequential control of the stock twin turbos. Ensure your vehicle's pinout connector matches the header shown in the product photos before purchasing. The G4X PlugIn ECU boasts a comprehensive feature set, including up to 6D fuel and ignition mapping, precision closed-loop four-cam independent control, and sequential fuel delivery. It offers digital triggering for all OEM patterns, supports OEM idle hardware, and features 5D boost control with three switchable tables. Advanced motorsport features like antilag, launch control, and flat shifting are included, along with continuous onboard barometric correction and individual cylinder correction. The unit also provides CAN port connectivity, QuickTune automated fuel tuning, and real-time selectable dual maps for fuel, ignition, and boost. It includes a USB tuning cable and provides 512MB of onboard memory for stats recording and data logging.
