G4X Monsoon Wire-In Bundle - ECU + Loom + Sensors
- The Link G4X Monsoon Wire-In Bundle is an engine management kit for 4-cylinder engines, including the MonsoonX ECU, a 2.5 m wiring loom, and temperature and pressure sensors.

G4X Monsoon Wire-In Bundle. Everything you need to get started with wiring a Link G4X MonsoonX ECU into your chosen vehicle.
This bundle is ideal for four-cylinder engines requiring a few additional features.
- G4X MonsoonX ECU
- Medium A Loom - 2.5 m wiring harness for G4X ECUs (MonsoonX)
- Intake Air Temperature Sensor
- Coolant Temperature Sensor
- Pressure Sensor
Bridging the gap between entry-level and mid-range ECUs, the MonsoonX delivers advanced tuning and motorsport features in a compact and versatile package.
Sharing the same championship-winning G4X architecture as the rest of the range, the MonsoonX guarantees the same proven tuning experience and reliability trusted by enthusiasts and professional tuners worldwide.
The MonsoonX shares the same processor, firmware, PC software and standard G4X feature set found throughout the G4X range. These features include CAN bus communication, Flex Fuel, configurable engine protection limits, CAN keypad control, open-loop and closed-loop boost control, dual closed-loop Lambda control, VVT control, a built-in Trigger Oscilloscope, aftermarket dash compatibility and 512 MB of onboard data logging memory. It also features a built-in MAP sensor.
Building on the capabilities of the AtomX, the MonsoonX adds extra auxiliary (Aux) outputs, digital and analog inputs, and advanced tuning and motorsport features. Depending on your input/output (I/O) requirements, features such as Launch Control, Anti-Lag, Gear Shift Control, Paddle Shift Control and VVT Control allow you to configure the ECU to meet the individual needs of your project.
The MonsoonX is an ideal solution for naturally aspirated and turbocharged engines requiring advanced tuning and motorsport features without the need to upgrade to a higher-end ECU from the Link range.
Note: The MonsoonX can support any of the above features, but not all simultaneously. The number of features that can be enabled depends on how many of the limited available inputs and outputs each feature requires.
