The Link G4+ range of engine management systems are already well known for delivering class-leading performance without sacrificing factory levels of drivability.

Why the Thunder?

You have been asking for more! More digital inputs, more analog inputs, more auxiliary outputs - more, More, MORE.

We have answered your call and give you the brand new G4+ Thunder with more of everything. Using the same pinout for the A & B connectors giving seamless upgrading from our other ECUs, the Thunder has 2 additional connectors (C & D) for increased capacity. This is the ECU for your high end applications requiring maximum performance, flexibility and tuning control, with the same sleek profile of our other G4+ ECUs

 NB: This ECU comes with 2 connectors (A+B) if you specify no loom. If you specify looms, you get Looms A+B and also connectors C+D (no looms are available for C+D)

  • Advanced fully configurable WireIn Engine Control Unit (ECU)
  • Most suitable for high end applications where multi electronic throttle bodies are used or where a large amount of IO is required.
