Advanced tuning features at an affordable price, welcome to the Link G4X StormX ECU!

The Link G4X StormX ECU is the latest version of our trusty, mid-sized ECU. With eight injector and eight ignition drives, it allows sequential injection and direct spark on engines with up to eight cylinders or four rotors.

The Link G4X StormX ECU is the most recent version of our tried-and-true mid-sized ECU. It supports sequential injection and direct spark on engines with up to eight cylinders or four rotors thanks to its eight injectors and eight ignition drives.

The Link StormX includes all of the improvements found in the AtomX and MonsoonX, as well as more advanced tuning features such as a built-in Trigger Oscilloscope, Stepper Motor Idle Control, Rotary Oil Metering Pump Control, Onboard Knock Control, Open and Closed Loop Boost Control, and most Motorsport features such as Full Gear Shift Control, Antilag, and Launch Control.

The Link StormX has more data logging capabilities and a higher bandwidth than its G4+ Storm predecessor. G4X offers 512 megabytes of 32bit logging on up to 250 channels, each limited to up to 1kHz per channel (by the operating system), with a maximum sample rate of 100 kSamples/sec.

It also has an 8x faster communications speed, allowing you to download logs 8x faster and quickly push all logging up to a new and improved PCLink, which is available for download in the features tab below.
