A premium ECU with Onboard Digital Wideband.


The FuryX is a premium ECU like the XtremeX, but with added Onboard Digital Wideband Lambda Control. Now on the G4X platform, the FuryX features a faster processor, faster communications & a huge 512 megabytes of data logging! 


With 8 injector drives and 6 ignition drives, the FuryX can control up to 3 rotors or 6 cylinders with sequential injection and direct spark, making it an excellent choice for professional level motorsport or more demanding road car applications.


The added benefit of a Onboard Digital Wideband Lambda Controller means higher accuracy of the unit, plus a simple setup. 


The FuryX comes supplied with stickers, a quickstart guide, a mounting bracket and a USB tuning cable. Requires 'A' & 'B' Looms or 'A' & 'B' Pin Kits, not supplied.


See the Specifications tab for a full list of specifications.
