This ECU distinguishes itself with a comprehensive array of inputs and outputs, surpassing other Link ECU models in functionality.

Additionally, two K-type thermocouple EGT inputs allow direct connection of EGT sensors without an interface box. The unit is constructed from die-cast aluminum with a black powder-coated finish and features a flush-mount extruded mounting bracket. It is equipped with a 40 MHz dual processor, comprising an engine control-specific MCU and a Digital Signal Processor, along with 32 Mbit of data logging memory. Connectivity options include USB for PC tuning, two CAN 2.0B ports, and an RS-232 connection. The ECU is rated IP54 for dust and water resistance and operates within a temperature range of -40 to +80°C.
