Link are redefining what an entry level ECU should be.
The Atom runs on the proven Link G4+ platform, has full configurability and is rated to IP67, making it dust and waterproof.
The Atom can control up to 2 rotors or 4 cylinders with sequential injection and direct spark. This makes it ideal for naturally aspirated engines that just need a retune and don’t need all the extra sensors and features that come with our higher level ECUs.

With the Monsoon you have all the tuning capabilities of the Atom, but you can also choose to run some of the following features: Gearshift Control, Launch Control, Anti-lag, VVT Control and Closed Loop Boost Control. It also comes with a built in 4Bar MAP sensor further reducing installation cost.
Note: The Monsoon will run any of the above features, but it cannot run them all at once. The amount of features you can run is dependent on how many of the limited Inputs and Outputs each feature needs.
The Monsoon can control up to 2 rotors or 4 cylinders with sequential injection and direct spark. 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.

The Kurofune is a direct replacement for a common aftermarket Japanese ECU, but with significantly more functionality and user configurability than the ECU it replaces. Sharing the same connector footprint and pinout to this ECU means there are already a host of aftermarket adapter looms that will allow the Kurofune to plug straight in.
Special hardware features included in the Kurofune, such as differential trigger inputs and analog outputs which can be used to emulate a MAF or oxygen sensor, makes it Link’s most suitable ECU for “piggy back” type installs.

The Fury has a similar spec level to the Xtreme but with added Onboard Digital Wideband Lambda Control.
With 8 Peak and Hold injector drives and 6 ignition drives the Fury can control up to 3 rotors or 6 cylinders with sequential injection and direct spark, making it a great choice for professional level motorsport or more demanding road car applications.
If it is sequential injection and direct spark for 8 cylinders you are after, consider a Storm, Xtreme or Thunder.
