LINK G4X StormX

Link G4X StormX ECU

Serious tuning power without the serious price tag. The Link G4X StormX brings advanced motorsport-grade engine management to a mid-size ECU, giving you sequential injection and direct spark control for engines up to eight cylinders or four rotors.

Why Choose the StormX

The Link G4X StormX builds on everything that made the AtomX and MonsoonX great, then adds the tools serious tuners actually ask for. It's the natural step up when you've outgrown a smaller ECU but don't need the full complexity or cost of the top-tier Link platforms.

Advanced Tuning Tools Built Right In

• Built-in trigger oscilloscope to diagnose triggering issues without extra hardware
• Onboard knock control with two knock inputs wired directly to the ECU; no external amplifier required
• Stepper motor or solenoid idle control
• Rotary oil metering pump control
• Open- or closed-loop boost control with up to three switchable tables

Motorsport-Ready Features

• Full gear shift control
• Antilag system
• Launch control
• Up to four fully variable closed-loop VVT cams

Faster, Deeper Data

• 512 megabytes of 32-bit internal logging across up to 250 channels
• Up to 1 kHz per channel (OS-limited), with a maximum sample rate of 100 kSamples/sec
• 8x faster communications than the G4+ Storm predecessor, so log downloads happen in a fraction of the time
• Feeds straight into the upgraded PCLink software for a smoother tuning workflow

Core Inputs & Outputs

• 8 injector drives and 8 ignition drives for sequential injection and direct spark
• 8 auxiliary outputs; unused fuel and ignition drives can be repurposed as extra Aux outputs
• 8 digital inputs, 8 analogue inputs, 3 temperature inputs and 2 trigger inputs
• +5V and +8V sensor power supplies
• 1x CAN bus and USB tuning connection

Engine Compatibility

• Distributed ignition (1–12 cylinder), wasted spark (2–12 cylinder) and direct spark (1–8 cylinder)
• Odd-fire engines, 2-stroke, 4-stroke and rotary configurations
• Configurable firing order and TDC points

Please Note

The StormX doesn't handle traction control, peak-and-hold injection, e-throttle or direct injection. For those applications, ask about the Xtreme, Fury or Force GDI ECUs instead. Running the full I/O set requires A and B looms or connector kits.

What's in the Box

• Link G4X StormX ECU
• Mounting bracket
• Wiring and installation instructions
• Link stickers (2 large, 2 small)

Manufactured to ISO 13485 standards.

Whether you're building a track-focused sequential setup or just want room to grow into motorsport features down the road, the Link G4X StormX delivers the tuning depth serious builds demand without stepping up to a full-size ECU.
