Show original supplier description

The Link G4X StormX ECU is a value-oriented, mid-sized engine control unit designed to provide advanced G4X tuning capabilities at a competitive price point. It features eight injector and eight ignition drives, supporting sequential fuel injection and direct spark ignition for engines configured with up to eight cylinders or four rotors. This wire-in ECU offers a robust feature set, including 8 digital inputs, 3 temperature inputs, 8 analog inputs, 2 trigger inputs, and 2 knock inputs. While it provides many advanced tuning functions, it is important to note that features such as traction control, e-throttle, or peak and hold injection are not included and would require considering higher-tier Link ECU models like the Xtreme or Fury. For a comprehensive list of specifications and technical details, users are directed to the manufacturer's detailed documentation. The StormX ECU is an excellent choice for enthusiasts seeking significant tuning potential without the premium cost associated with top-of-the-line ECUs, making it a strong option for performance engine builds.
