Show original supplier description
The Link Engine RX7S6X G4X PlugIn ECU provides advanced engine management technology for the Mazda RX7 Series 6 13BT. While it offers extensive features such as up to 6D fuel and ignition mapping, precision closed-loop cam control, and 5D boost control, it does not support the sequential control of the stock twin turbos. Additionally, a modification is required before the E-Throttle functionality can be utilized. Key features include digital triggering, support for OEM idle hardware, and motorsport functionalities like antilag, launch control, and flat shifting. It also boasts continuous barometric correction, a CAN port, QuickTune for automated fuel tuning, and individual cylinder correction. For expanded capabilities, the ECU provides I/O expansion options including analog inputs and digital inputs.
