Applicability
Link G4X XtremeX; do not substitute the earlier G4+ wiring file.
Model and software
XtremeX provides eight injector, eight ignition and eleven analogue voltage inputs. It lacks FuryX’s internal LSU 4.9 driver; lambda measurement needs an external controller and a matching signal format.
I/O and electrical limits
A shared pin can perform only one function at a time. Check physical pin overlap when allocating CAN, digital inputs, throttle and auxiliary outputs.

Sensor and driver connections
Connect sensor ground, power ground, 5 V reference and 0–5 V signals to their assigned pins. Match trigger type and edge, ignition power stages, and injector / solenoid impedance and current.
PCLink and first-start checks
Install the matching PCLink generation and drivers, then preserve the existing map and firmware details. Check static sensors, I/O tests, cranking sync and locked ignition timing. The matching F1 help explains detailed settings. G4X logging is limited to 100 kHz across all channels.
