Link G4+ Monsoon ECU:

The Link G4+ Monsoon is a step up from Link Engine Management Entry Level Atom ECU with some extra features including Onboard 4 bar MAP sensor & Motorsport features such as Gearshift control , Launch control, Anti Lag, VVT Control and Closed Loop Boost Control.

The Monsoon ECU can run any of the above motorsport features however not all at once; it is dependant on the number of limited inputs and outputs the feature needs.
