Link G4X MonsoonX ECU | Compact ECU with Big Features

The Link G4X MonsoonX is a compact ECU that delivers big features without the cost of a full motorsport unit. It supports up to 4 cylinders or 2 rotors with sequential injection and direct spark, or up to 8 cylinders in batch fire mode, making it ideal for turbocharged or naturally aspirated street cars that just need that little bit more control.

With upgraded logging, precision control, and features like Launch Control, Antilag, VVT, and Closed-Loop Boost Control, the MonsoonX is a huge upgrade over the AtomX. It now includes onboard Knock Control and a built-in 4-bar MAP sensor, keeping your install simple and cost-effective.

Requires an “A” loom (sold separately).

Note: MonsoonX cannot run all features simultaneously. Available I/O determines how many features can be active.
