Link G4X MonsoonX ECU Standalone Engine Management System

  • Sale
  • Regular price $1,095.00


The Link G4X range of engine management systems builds upon the previous G4+ ECUs by featuring an all new micro-processor, an upgraded communications chip and expanded data logging. These improvements allow for a more responsive and accurate tune, much faster download speeds and far greater internal data logging capacity.

The Link G4X range of engine management systems are well known for delivering class-leading performance without sacrificing factory levels of drivability. 

The Link G4X MonsoonX ECU has all the tuning capabilities of the AtomX, but you can also choose to run some of the following features: Launch Control, Anti-lag, VVT Control and Closed Loop Boost Control. It also comes with a built in 4 bar or 7 bar MAP sensor further reducing installation cost. In addition to all those features, the MonsoonX also features Knock Control to further improve performance.

NOTE: The MonsoonX will run any of the above features, but it cannot run them all at once. The number of features you can run is dependent on how many of the limited Inputs and Outputs each feature needs.

With 4 injector drives and 4 ignition drives, the MonsoonX will control up to 2 rotors or 4 cylinders with sequential injection and direct spark. Or, it can be used for up to 8 cylinders using batch fire. This makes it ideal for naturally aspirated or turbocharged engines that just need a retune and one or two extra features, so you don’t need to jump up to one of our higher-level ECUs.

Now on the G4X platform, the MonsoonX features a faster processor, faster communications & a huge 512 megabytes of data logging! Control loops are also more precise compared to its G4+ predecessor, along with advancements such as single precision floating point format fuel tables, better resolution within ignition timing and faster communications. These upgrades make the G4X Monsoon a true powerhouse in a small shell. 

G4X features logging at 32bit using up to 250 channels, each limited to up to 1kHz per channel (by the Operating System), with a maximum of 100 kSamples/sec. It also features 8 x faster communications speed, allowing you to download logs 8 x faster and pushes all the logging quickly up to a new and improved PCLink.

NOTE: If Onboard Digital Wideband Lambda Control is required, consider the FuryX.
