Overview
Positioned between Link's entry-level and premium G4X ECUs, the StormX delivers performance, flexibility and value.
It includes all the core G4X features expected from Link's championship-winning platform, including CAN Bus, Flex Fuel, Flexible engine protection limiters, CAN Keypad Control, VVT Control, Open and Closed Loop Boost Control and 512MB of data logging.
The StormX includes increased I/O and advanced functionality beyond Link's entry-level ECUs with additional injector and ignition drives, auxiliary outputs, digital inputs, and temperature inputs. It also introduces advanced tuning features including a built-in Trigger Oscilloscope, Stepper Motor Idle Control and Rotary Oil Metering Pump Control.
Drawing from Link's premium G4X range, the StormX also supports some advanced motorsport features including Nitrous Control, Launch Control, Full Gear Shift Control and Anti-Lag, making it a smart choice for high-performance street and motorsport applications.
The StormX is the ideal solution for builds requiring expanded I/O and some advanced tuning capability, without needing the extra features that come with our premium ECUs.

The table is going to need the following footnotes somewhere, preferably at the bottom:
‡ G5 Voodoo Pro has 12 inj, 8 ign, plus 4 multipurpose (inj, ing, aux) drives (24 total). † Check Specific pinout for number of I/Os exposed.
† Check Specific pinout for number of I/Os exposed.
# 4 pins are multi-purpose Aux or Digital Input pins. Each pin can be either Aux or Digital Input, not both at the same time.
* 2 Digital Inputs required when using 2nd CAN Bus.
§ 4 pins are multi-purpose Injection, Aux or Digital Input pins. Each pin can be either Injection, Aux. or Digital Input, not all at the same time.
Link ECU products should not be used where they interfere with a vehicle’s safety or emission control features. (no footnote symbol on this one).
