Link G4X StormX Standalone Engine Management ECU The Link G4X StormX is a mid-sized standalone engine control unit designed for advanced tuning applications. Featuring eight injector and eight ignition drives, it supports sequential injection and direct spark for engines with up to eight cylinders or four rotors. The StormX incorporates expanded data logging, high-speed communications, and a comprehensive suite of tuning and motorsport features. Key Features Eight high current injector drives (supports high impedance injectors) Eight ignition channels Eight auxiliary outputs (all PWM capable; Aux5-8 can control stepper motors and drive high or low) Eight digital inputs (capable of reading frequencies up to 10kHz) Three temperature inputs (configurable pull-ups on ANT1 and ANT2) Eight 0-5V analog inputs Two trigger inputs (supports reluctor, optical, or Hall sensors) Two knock inputs (onboard knock control, supports two knock sensors wired directly to the ECU) Onboard barometric pressure sensor +5V and +8V sensor power supplies Engine configurations: 1-12 cylinder distributed, 2-12 cylinder wasted spark, 1-8 cylinder direct spark, odd fire engines, 2-stroke, 4-stroke, and rotary engines Configurable firing order and TDC points (for odd fire) Built-in trigger oscilloscope Stepper motor idle control and idle valve solenoid control Rotary oil metering pump control Open and closed loop boost control with up to three switchable tables Full gear shift control, antilag, and launch control Up to four fully variable closed loop VVT cams Expanded data logging: 512 MB of logging at 32-bit, up to 250 channels, 1kHz per channel, maximum 100kSamples/sec Upgraded communications chip (at least 8x faster than G4+ V2) One CAN bus and one USB tuning connection 150 MHz specialized engine management microprocessor Ignition control to 0.1 degree, fuel to 0.01 ms 32-bit floating point calculation, 12-bit ADC resolution Operating voltage: 8–22V, operating current: 200mA Internal temperature range: -10°C to 85°C; ambient temperature range: -30°C to 90°C Electrical protection on all inputs and outputs Manufactured to ISO 13485 standard What's Included G4X StormX ECU Wiring and installation instructions 2 large Link stickers 2 small Link stickers Vehicle Fitment Not specified by manufacturer Installation Notes Requires “A” & “B” looms or “A” & “B” connector kits for installation For traction control, peak and hold injection, or e-throttle, consider Xtreme or Fury ECUs StormX QuickStart Guide and PC Link tuning software are available for download from the manufacturer
