G4X Explained
G4X Explained
G4X, the legend continues
The championship winning G4X Range of ECUs is still recommended for many applications. If you are not running direct injection, needing over 8 injectors, don’t need the extra inputs and outputs and can do without the new features like GPS and Wi-Fi, then G4X is still the high-performance ECU for you.
The full G4X range was released in August 2020 and is one of the most trusted platforms in the motorsport electronic industry. G4X is often regarded as the most reliable ECU on the market, with a reputation of simply working out the box and being easy to use.
G4X is race proven the world over, meaning that G4X ECUs have powered many championship winning vehicles, broken many records such as the fastest Skyline in the world, and has been proven in Drift, Circuit, Drag, Jetboats, Off-road, snow mobiles, airplanes and many other applications.
Link will continue to manufacture and sell the G4X range for years to come and will continue to provide free software updates, free support via live human tech support. Plus, we will continue to back it with Link’s limited lifetime warranty.
The trusted high-performance solution.
The G4X range of ECUs is still a world leader in its class and has many advanced features such as:
- One of the fastest microcontrollers (computers) on the market
- Traction Control
- Launch Control
- Anti-lag
- Flappy Paddle Control
- Race Timer
- Flex fuel
- E-throttle Control
- VVT Control
G4X also features 512 megabytes of logging at 32bit using up to 250 channels, each limited to up to 1kHz per channel (by the Operating System), with a maximum of 100 kSamples/sec. This makes for very useful data logging capacity for motorsport applications, throughout the entire G4X range.
