This advanced engine management system offers a comprehensive suite of features, including up to 6D fuel and ignition mapping for precise control, precision closed-loop cam control for independent operation of up to four cams, and sequential fuel delivery. It also boasts 5D boost control with three switchable tables, enabling dynamic boost management based on various parameters. For performance enthusiasts, integrated motorsport features such as antilag, launch control, and flat shift are included. Further enhancing its capabilities, the G4X PlugIn ECU features continuous barometric correction, a CAN port for connectivity, QuickTune for automated fuel tuning, and individual cylinder correction. It supports a wide range of sync and crank sensor combinations (Hall effect, variable reluctance, or optical) and offers gear, speed, or throttle position-referenced boost control. The unit also provides 512MB of data logging memory and staged injection, along with knock control with "windowing" for engine protection. This ECU is exclusively compatible with manual transmissions. It is suitable for FD3S Series 7 and Series 8 RX7 models. While it supports naturally aspirated, parallel twin, or single turbo setups, it does not support the sequential control of the stock twin turbos.
