MonsoonX
More features, more power.
The MonsoonX can control up to 2 rotors or 4 cylinders with sequential injection and direct spark - or up to 8 cylinders in batch-fire mode. This makes it ideal for naturally aspirated or turbo engines that only need tuning and one or two additional functions - without having to resort to a higher-level control unit. The MonsoonX control unit has been upgraded and now features 512 MB of data logging memory. This allows significantly more data to be recorded at a higher sampling rate. The control algorithms have also been improved compared to the predecessor G4+ - including:

• Single-precision floating-point calculation in the fuel tables
• Higher resolution in ignition timing calculation
• Faster data communication

These improvements make the G4X Monsoon a real powerhouse in a compact format.

Logging function (data recording):

• 512 MB memory
• 32-bit resolution
• Up to 250 channels
• Max. 1 kHz per channel (system dependent)
• Max. 100,000 samples/second

Compared to the AtomX, the MonsoonX offers additional tuning features:

• Launch Control
• Anti-Lag
• VVT control
• Closed-loop boost control
• Integrated 4-bar or 7-bar MAP sensor (saves installation costs)
• Now also with knock control

Note:
The MonsoonX can perform all the functions mentioned above, but **not simultaneously**. The number of features that can be used simultaneously depends on the limited inputs and outputs required by each function.
