Applicability
Link G4X MonsoonX; earlier G4+ Monsoon uses another guide.
Model and software
MonsoonX uses one A connector, four injector, four ignition and six auxiliary outputs. It has no internal throttle motor driver; unused injector outputs are not ordinary auxiliary switches.
I/O and electrical limits
Allocate the MonsoonX’s 4 digital inputs and auxiliary channels according to the actual functions required. On V3.0 and later hardware, the knock input uses the DI4 pin, which cannot also serve as a digital input.

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.
