A totally new ECU


Why a new ECU?

Atom, Storm and Xtreme, a winning line up

  1. Atom - A powerful entry level ECU
  2. Storm - Perfect mid range ECU, ideal for 4 cylinder applications
  3. Xtreme - Powerful high end engine management

Your feedback is that it's a big step up from the Storm to the Xtreme, too big!


Introducing the Fury G4+

The Fury G4+ is a fully featured, 6 cylinder ECU to fill the gap between the Storm and Xtreme, just as you asked.




Digital Wideband

Superior wide-band control onboard the Fury


Our control is digital!


Other ECU manufacturers use cheap old analogue controllers that are easy and fast for the ECU designers to implement but ignore the capabilities of modern O2 sensors error correction & diagnostics abilities. Worse still, many ECUs and after-market wide-band controllers use their own basic, bare bones circuit designs to control the sensor.


The wide-band controller IC in the G4+ Fury is so comprehensive that if we were to build it out of discrete components it would be as complex as our entire ECU and still not as excellent as the IC we use!


Our Digital Wideband Controller

  • Current OEM technology wide band Lambda sensor control
  • Full digital sensor control and interface.  No loss of signal measurement precision
  • All sensor control is performed using a Digital Signal Processor (DSP) eliminating risks, delays and measurement errors caused by analog alternatives
  • Advanced sensor protection such as automatic blackening prevention
  • High speed sampling (1.5 kHz) results in fast sensor response - thats one thousand five hundred samples per second!
  • Uses sensors with internal reference cell to prevent drift with ageing
  • Makes full use of sensor OEM calibration resistor to avoid the need for manual per-sensor calibration
  • Continuous measurement, correction and compensation to correct for all wiring, component and circuit errors and changes
  • Exhaust temperature correction
  • Automatic shutoff and protection for sensor wiring short circuits
  • Advanced sensor and circuit diagnostics not available in analog controllers
  • Shortest startup to sensor measurement valid time




Optimised for 6 Cylinder / 3 Rotor

"Storm and Atom are 4s, Xtreme is 8, we need a 6"  


Done, introducing our new six cylinder ECU, the G4+ Fury with 6 x ignition outputs and 8 fuel outputs.


"Hey, that's an eight cylinder ECU!" -  Sneaky aren't we!





On Board e-Throttle

Of course, welcome to the 21 century. 




There's Much More

The Fury G4+ has many, many more features. Full feature information will be available on release in early April.
